【Factorio】Aquilo Strategy and How to Build a Cryogenic Factory

When you first land on Aquilo, equipment arranged with the same approach as Nauvis tends to shut down in clusters. Unheated facilities freeze, concrete is required on ice, robots consume 5× power, and solar panels work at just 1% of Nauvis output—once you understand these numbers, your design priorities flip entirely.

I also experienced it firsthand: even with expanded solar panels, the power meter barely moved, and the moment I extended my robot network, power plummeted into the red zone. It felt like I'd truly arrived on an alien world. To build your first stable foothold on Aquilo in Space Age, the answer is clear: lay floors and thermal infrastructure first, equipment second.

This article walks you through site selection, ice platforms, concrete, heat sources, heat pipe trunk lines, and minimum production setups in order. It explains how to prevent freezing by densely clustering equipment around heat pipes as the core axis, using numbers and design principles to make the startup approach clear and accessible.

Aquilo Strategy Basics | Essential Knowledge About an Extreme-Cold Factory

Target Version and Planetary Positioning

Aquilo is the dedicated ice planet in Space Age, a paid expansion released on 21 October 2024. it's an ice world that doesn't appear in the base game alone, and its startup design philosophy differs significantly from Nauvis.

In terms of positioning, it's not "a cold planet" but rather a planet where you must first engineer survival conditions before your factory can operate. On Nauvis, power and logistics come first; on Aquilo, heat joins the list as core infrastructure. I initially arrived with the assumption that lining up assemblers and feeding materials would work—but only the ones touching heat pipes ran, while others fell silent. That taught me immediately: on Aquilo, "placeable" and "functional" are two different things.

Aquilo also has its own science type: the Cryogenic Science Pack. In other words, this is not a side mission but a full-fledged challenge integral to Space Age progression. That said, if you misunderstand the mechanics from the start, reworking your base becomes very costly.

Freezing and Heating: The Core Rule

The most critical rule on Aquilo is: many entities freeze and stop functioning unless they're adjacent to a heat pipe that's conducting heat. This isn't "some machines dislike the cold"—it means your entire factory's baseline operation requires active heating.

What makes this rule tricky is that it looks like placement succeeded, so newcomers often misdiagnose the cause as insufficient power or delivery issues. Materials and electricity arrive fine, but machines stop because they're not receiving heat. My first lesson on Aquilo was watching an entire row of assemblers freeze because they didn't touch the heat pipe, then seeing them all burst to life the moment I connected it. Once you see that before-and-after, your design instinct naturally pivots to "heat-line-centric."

The design principle here is straightforward: don't place equipment as scattered points; arrange them as a continuous band along the heat line. If you wait to add heating later, you'll miss frozen machines. Better to decide the heat trunk first, then fit assemblers, conveyors, and power poles within its reach zone. The troubleshooting becomes vastly easier.

Ice Cliffs, Ice Platforms, and Concrete Floors

Aquilo's land use is also unique. Ice cliffs and ice platforms, by themselves, don't function as usable factory land. Most structures require concrete flooring—or its variants—to be practical. In other words, the ground looks present but is geologically "unbuilt cold terrain."

This rule hits hardest during expansion. Native ice cliffs suit early startup; ice platforms let you reclaim ammonia sea and expand much later. But both become real factory foundations only after flooring. Without understanding this, many accidents happen. I initially treated sea reclamation as "free expansion," not realizing that "fill the sea" and "install insulated building floor" are separate work phases.

There's also melt risk: heated heat pipes in contact with uninsulated ice can cause the ice to melt, so trunk layout should be planned alongside flooring.

Compared across options, Aquilo's building land breaks down like this:

Looking at this table, it's obvious: Aquilo building isn't "place structures in empty spaces"—it's converting only those places where you can sustainably run floors and heating into factory. That's the foundation.

5× Robot Power Draw and Design Impact

Aquilo's construction and logistics robots consume 5× normal power. This dramatically changes heat-independent logistics design, so limiting robot usage early is wise.

The impact is significant, and the conclusion is: don't make robots the core of your transportation network. Construction robots excel at high-value short-term work—laying floors, site prep, repairs. But if you fully roll out logistics robots, charging burden compounds and generation demands spike. I expanded roboports too casually myself and watched my whole base turn unstable as power bled into robot charging.

Here's how logistics methods align with Aquilo:

The key isn't "never use robots"—it's use them sparingly. Short-term, large-area work like floor laying and bulk construction is where they shine. With modular design, you can duplicate heat/floor/equipment layouts without breaking the pattern. The alternative: steady-state ore or intermediate-item transport works better with belts or direct handoff on Aquilo.

Solar at 1% (0.6 kW/day)—What It Means

Aquilo's solar panels output 1% of Nauvis, at just 0.6 kW per day. That number means: not "weak backup," but off the primary-source list entirely.

On Nauvis, solar and batteries solve a huge chunk of power problems. Bring that thinking to Aquilo and panel expansion feels like throwing material into a void. I tried filling shortfalls with solar and watched the meter barely budge despite massive panel sprawl. The maths are unforgiving: at 1% output, your instinct for panel counts is almost useless.

So your power strategy needs immediate revision:

The trick: don't separate power generation from heating infrastructure. To run a factory you need both electricity and heat, so your core backbone naturally tilts toward heat supply. When heat-based layout becomes your reference frame, power decisions stop wavering.

This Article's Confirmed vs. Speculative Information

From here on, only confirmed numbers and mechanics form the foundation. These are Wikipedia-verified facts: Aquilo is a Space Age–exclusive planet; unheated equipment freezes; ice cliffs and platforms need concrete floors; robot power is 5×; solar is 1% and 0.6 kW/day; and heated heat pipes adjacent to uninsulated ice carry melt risk.

However, precise heat-source superiority rankings, optimal trunk spacing, minimal direct-placement ratios—that granular comparison data isn't yet available in confirmed form. Rather than force numbers, I'll stick to design principles: "run heat first," "cluster equipment near heat," "don't overextend robots," "pre-plan floors and insulation before expanding offshore." These work even without fine detail.

I take this boundary seriously. Factorio rewards number-driven thinking, but incomplete numbers in published design lead readers into accidents. Aquilo demands this caution especially. I'll keep separating "confirmed rules" from "safe design principles derived from them" throughout.

Building Your Aquilo Outpost | Heat, Floor, Power First

Step 1: Choose Your Site

Before picking production equipment, decide which zones merit heating and flooring. Aquilo failures usually start where you placed gear. Drop machines in vacant ice before laying floor and heat, and you'll chase infrastructure through a tight maze. Early on, native ice cliffs are easier—pre-shaped, easy to partition, heat routing obvious. For future expansion, though, reclaiming ammonia sea with ice platforms opens room, but treat the platform as raw material, not finished building land. You must add flooring first.

I tend to frame early layout around a central heat source, with short-loop small factories nearby. Spreading equipment far from the trunk only raises difficulty on Aquilo. Dense heat-reachable zones beat sprawl.

Ice platform

Step 2: Lay Ice Platforms

If space runs tight or terrain doesn't cooperate, expand with ice platforms. Treat them as raw building substrate, not finished floor. A level surface isn't a complete factory foundation. When heat equipment is nearby, you need to plan both heat-passage routes and flooring zones simultaneously, since uninsulated ice near heat melts (see official docs for thresholds).

I expand offshore by making fine linear strips initially, instead jumping across; I aim for heat-sourceable rectangles. Aquilo isn't a game about claiming plaza space—it's about shaping land so infrastructure flows without strain. Your later steps become far smoother once you internalize that.

Step 3: Concrete Flooring Means "Insulated" & "Buildable"

Whether on ice cliffs or platforms, convert the ground with concrete floor next. Skipping this leaves visually-placeable but functionally-broken terrain. Aquilo's early bottleneck is floor scarcity, not machine shortage.

This step serves two roles. First: makes buildings placeable. Second: creates insulated work surfaces where heat and trunk lines can safely run. Floors aren't cosmetic; they're survival infrastructure. Rather than point-placing under machines, pave full bands for trunk and production lanes together. Expansion becomes far more robust.

I learned this the hard way: placing assemblers on minimal floor left no breathing room. Expansion locked up immediately. Laying floor broadly first, then securing a heat-pipe corridor, transformed the entire flow.

Step 4: Fire Up Heat Source & Test Early

Once flooring exists, run the heat source before the equipment clusters. Rather than compare source output minutiae, the key point: test heat supply before stacking production. This approach means all later equipment sits only in zones where heat is confirmed running. The reverse—stacking machines first—leaves you guessing whether stoppages stem from cold. On Aquilo, freezing is the usual culprit, so diagnosing early heat flow is a huge win.

I don't just place the heat source alone—I run a test trunk segment into the factory band. I'm checking "can I route heat from this source into the production zone?" not "does the source exist?" Early power also anchors to this heat source, supplemented by external import during startup only. This prevents initial wobble.

Step 5: Heat Pipe Trunk → Branches

Once heat runs, now you lay heat pipes in earnest. Principle: trunk first, branches minimal. Imagine heat highways before building roads off them. Equipment clusters near the trunk, not scattered far. Close packing simplifies heat delivery and layout simultaneously. Long branches to distant islands are far trickier: they warp your trunk geometry, stretch all secondary lines, and make diagnostics nightmarish.

My stable pattern: linear trunk with equipment in ribbons flanking it. Furnaces, assemblers, and belts sit close to the heat line, not as remote islands. That adjacency is both mechanical guarantee and layout discipline.

Step 6: Wire Minimal Production & Power

Here, finally, you place production equipment. Start minimal and essential. Assemblers, conveyors, needed processors—arrange near the heat trunk, run power alongside. Think "land a tiny loop on the heated infrastructure band," not "complete the factory." Power ties to the heat source too, supplemented early by external import. Aquilo asks you to stabilize heat and electricity together, not sequentially.

Transport: belt or direct adjacency work smoothest here. Robots burden power heavily at this early stage. I compounded overconfidence in robot sprawl with wall-to-wall outages. Short-haul belt chains along the heat trunk, however, proved rock-solid.

This sequencing's secret: run survival infrastructure before production hardware. Floor, heat, power—the backbone. Affix machines after. Aquilo factories then run with shocking smoothness.

Extreme-Cold Factory Layout | Heat-Pipe-Centric Design

Heat Trunk Design

Aquilo factory stability isn't "place functions broadly, link later with logistics"—it's root everything in running heat from source to cluster. Machines need heat-pipe adjacency, so trunk placement first, machine placement second is rational.

My trunk rule: straight priority, minimum branching. Reason: fragmented intent. Bends and sidelines blur "where am I heating?" and make endpoints flaky. Tight, straight trunks with production bands on both sides beat scattered islands every time. Temperature holds better, expansion is easier.

Linear, dense: machines hug the trunk on one or both sides. Each machine's distance to heat is short and clear. Power and belt routing nest naturally within the band. Heat, electricity, and flow align automatically.

Scattered Layout Fails; Clustered Wins

Spread-out placement suffers: every distant machine demands branch-line heat, power, and goods. The return is tiny; management complexity explodes. Flank islands stop unpredictably, diagnosis drowns in branches.

I tested it: spreading by function, threading heat through each sector, caused pattern-end fridging—only the far row froze. Branch heat couldn't hold temperature uniformly. Re-gear to linear trunk with equipment massed nearby? That row never froze again. Heat, power, and short conveyors let it all breathe.

Clustered shines for transport too. Near machines use inserters, brief belts, or hand-off. Aquilo favors all three. Nearby beats routed over Aquilo's harsh power and heat constraints.

Logistics Picks: Belts vs. Robots (5×) vs. Direct

Logistics choice intertwines with heat-centric layout tightly. Verdict: belts standard, direct adjacency where possible. Robot logistics burden power at 5×; as constant backbone, they choke. Ample building means abundant power sinks—inserters and belts dwarf that load. I went robot-heavy early; charging backup strangled the base. Belt spine alongside the heat trunk instead? Rock-solid.

Three-way trade:

Robots suit construction help, one-off rescues, light cross-map haul. Quantity lanes belong to belts or touching. This philosophy pairs perfectly with heat-trunk-flanked density.

Power Source: Solar 1%/0.6kW/day, Heat-Dominant, External Hybrid

Power stance ties to layout ideology. Solar at 1%/0.6 kW/day is off the board. Nauvis-scale panel-and-battery logic dies here. Instead, heat-source-primary wiring is coherent. Plant heat at centre, trunk outward, production and generator near. "Warm zone" and "power user" nest together. Aquilo rewards unified heat+power nodes over divorced networks.

External supply helps at startup: shore production while the thermal core grows. Steadily replace import with onsite output rather than chasing self-sufficiency instantly. Later stages flow smoother.

This aligns with Aquilo wiki: self-contained heat-rooted design outpaces retrofit-heavy work.

Simple Layout Template

Words alone confuse layout. My lightweight setup conceptually:

[Heat Source]
   │
   ├─ Short Heat Pipe Trunk ─────────────────┐
   │                                          │
[Warm & Power Hub]                      [Warm & Power Hub]
(Power Pole / Steam Gen, etc.)          (Power Pole / Steam Gen, etc.)
   │                                          │
   ├─ Left: Furnace Furnace Furnace
   ├─ Trunk-Side Belt
   └─ Right: Assembler Assembler Assembler
        ↑ Close work uses direct hand-off

Perks: short trunk, left-right face layout, heat-pipe-adjacent machines. Furnace bank and assembler bank both hug the heat route, staying toasty. Single spine belt serves both flanks; short processes use touching. Power hubs at the spine or endpoints keep temperature and electricity pooled, expansion direction unambiguous.

Avoid: scattering machines far, threading branches to each, forcing heat to meander. Layout looks free; instability runs deep. Aquilo's rule favors a spinal core and flanking production instead.

Common Pitfalls & Defences | Freeze, Floor Shortage, Ice Melt

Building Without Flooring

Aquilo's first trap: "I placed it, so it works"—but doesn't. Ice cliffs and platforms let you drop structures, but not use them. Nauvis floor-free habit dies here. Pour concrete floor first; place machines second. I raced to stack buildings on bare ice and hit a hard wall—not build error, just no finished floor to stand on.

Lesson: treat floors as core infrastructure. Aquilo building is "floor zoning, then machine placement," flipped from Nauvis. Especially during expansion: lay the floor band before copying-pasting your production blueprint. This sidesteps half your growth headaches.

ヒートパイプ非隣接で設備が止まる

Heat-Pipe-Absent Equipment Stops

Next snare: power arrives, goods arrive, yet the machine silent. Heat wasn't running through. Aquilo's cruel twist—no alert noise, just dead weight. Spread layout blinds you most: outer edge freezes unpredictably.

Fix: stack machines along trunk ribbons, where heat-pipe touch is obvious. Lay machines row-by-row, each touching the trunk. Diagnosis turns instant: frozen? No heat pipe there. Added? Wakes right up. Config matters for temperature, not just cosmetics.

Spacing kills quietly. Machines apart "look" fine; they're silently frozen islands. Squeeze them near the trunk.

Ice Platform Melts From Nearby Heat

The trap: "heating matters, I'll run heat everywhere"—except ice platform near heat melts. This is Aquilo-exclusive pain. Heated pipes touching uninsulated ice damage the bedrock itself (thresholds in official docs).

Guard: treat heat-pipe as "high-temp equipment," not "safe utility." Floor side gets insulation thought; route heat within, not along edges. Worked hard to expand an ice platform, lost chunks to careless heat—avoid that.

Warming and preserving land need joint planning. Aquilo demands both.

Chasing Shortfalls With Solar Expansion

Temptation: shortfall shows → add panels → barely moves. Aquilo's solar is neutered. I dumped panels and watched meters stay flat—it's hard to accept but critical. Reframing to heat-primary is the fix.

This meshes with wiki: Aquilo removes solar's usual primacy. Design around that reality from day one.

Robot-First Sprawl Drains Power

Convenience trap: sprawl the base, robot it together. Aquilo's 5× robot power makes this lethal. Charging queues compound; core production starves. I expanded robot networks and watched basewide instability cascade.

Route: belts on the quantity lines. Robots for one-offs, construction, small gaps. A trunk-tight dense zone beats a robot-threaded sprawl in Aquilo every metric. Power, heat, and work all stay packed and stable.

Robots aren't forbidden, just secondary tools.

Path to Cryogenic Science Pack

Short-Term Goal Framing

Your early aim isn't instant Cryo pack production. Instead: build a heat-stable outpost. Only then does pack output make sense. Jumping straight to recipes before the base stops freezing means heat, power, or material flow collapses mid-production. Aquilo demands baseline stability before science chasing.

I frame early wins as "production zone that stays warm and fed without player babysit." That, finished, becomes your launchpad for Cryo recipes. Early import shoring isn't shameful—it's smart until thermal core stabilizes.

Minimal Production Line Structure

Design around "one heated block = one function". Heat trunk nearby, assemblers, input, output, power—all short range, one zone. Aquilo rewards small stable cells over sprawling plants. Per-zone wins let you spot bottlenecks. Add next block only once prior runs steady.

Transport: belt or adjacency, as covered. Ropbot's power burden makes early reliance risky. Cryo pack approach shouldn't fight the planet's grain.

This build-and-test flow keeps low-temp science reachable without redesign stress.

Recipe/Ratio Data: Wiki-Verified Confirmed Values

レシピ/比率データは公式参照で確定値運用

Details like Cryo pack recipes, ingredient counts, and machine ratios: Aquilo penalizes imbalanced ratios harshly—shortfall doesn't just reduce yield, it stops the zone cold until reheating. Guessed ratios into a half-built layout means painful rebuilds.

I've learned: confirm specs, then lock machine counts and space. For Cryo target, verify each ingredient recipe, calculate machine ratios, allocate block size, then place. Mid-design number swaps on Aquilo blow apart heat routing.

Workflow: reserve block placement and input sources. Await confirmed recipes. Plug final counts. Launches smoothly then.

Advanced: Blueprint-Ready Cryogenic Factory Units

One Heat Trunk = One Module

For future expansion ease, define "heat trunk + flanking zones" as one duplicate unit. I treat this not cosmetically but as a heat-proof, work-guaranteed minimum cell. Trunk spine, left/right production bands, each holding process gear, feeding, draining, power. Copy that shape sideways without fiddling "are they heated?" each cycle.

Perk: repetition kills design churn. Add another module, and you're assured heat coverage repeats. Sprawl-then-retrofit thinking dies; modular add-ons thrive.

I favour: 2 furnace bands + 2 assembler bands per trunk as base. Left/right split tasks: raw material vs. parts vs. intermediate. Shortages? Duplicate an existing block. Rework stops. Expansion accelerates drastically.

Construction Plan Tools: Save & Organise

Module design only shines if you save it. Use Construction Plans (one blueprint), Construction Plan Books (bundled storage), and Construction Plan Libraries (permanent library).

Workflow: save trunk+zone as a Plan. Bundle variants in a Plan Book. File Aquilo plans separate from Nauvis (different heating rules = recipe hazard). I sort by role: "furnace," "assembly," "power backup," "input/output." Repurpose becomes instant—no fresh design each base.

Capture not just building layout but heat-relative position, belt direction, I/O face. Aquilo reuse works only if temperature premise is locked. Swappable guts matter less than fixed thermal/transport exterior.

Blueprint

wiki.factorio.com

Replicate Small Heated Blocks for Scale

Scale not via one mega-plant but replicate small proven blocks. Aquilo production scales on unit count, not sprawl. A small stable block duplicated three times beats a sprawling mismatched design every time. Temperature, goods flow, all lock together. No per-expansion math—just copy and connect.

Tactile shift: rather than "how big should my smelter array be," ask "how many units do I need?" Units stack horizontally, thermal/power overlap naturally stays sound. Bottleneck? Add unit. Imbalance? Duplicate and rebalance smaller. Aquilo's quantity game is about modular self-sufficiency, not monolithic scale.

Conclusion | On Aquilo, Build Liveable Floor & Heat Before the Factory

What comes first on Aquilo isn't the factory look—it's an operating environment. Follow sequence—floor, heat, power, goods—and stability soars. Heat-source-centric clusters beat solar or robot sprawl by a mile. Keep confirmed rules wiki-anchored; measure spacing and placement on-site as you build.
