ARC Coolant is a Rare crafting material you salvage from destroyed ARC machines in ARC Raiders. It sells for around 1,000 Raider Coins, recycles into a stack of Chemicals for crafting, and is one of the cleaner "kill-and-loot" materials in the game — no keys, no puzzle rooms, just find the right ARCs on the right map conditions and strip them for parts. Here's exactly what it is, which enemies drop it, the fastest way to farm it, and whether you should sell it or break it down.
TL;DR — Key Takeaways
- ARC Coolant is a Rare, recyclable material salvaged from destroyed ARC machines — not scavenged from containers like loot trinkets.
- It sells for ~1,000 Raider Coins, stacks to 3, and weighs 1 kg — a strong coin-per-slot item to carry out.
- Recycling one ARC Coolant returns a batch of Chemicals (trackers list up to 16), the basic material used to craft medical supplies, explosives, and utility items — but you get fewer coins than an outright sale.
- Best farm: high-loot red danger zones, and electromagnetic storm map conditions where Baron Husk ARCs on Blue Gate, Dam Battlegrounds, and Spaceport drop it reliably.
- Don't confuse it with Impure ARC Coolant or plain Coolant — those are different items with different uses.

What is ARC Coolant in ARC Raiders?
ARC Coolant is a Rare-tier crafting resource that comes out of the ARC machines you destroy on Topside. As the ARC Raiders Wiki puts it:
"ARC Coolant is a Rare item scavenged from destroyed ARC machines." — ARC Raiders Wiki
That one line tells you the most important thing about farming it: you don't find ARC Coolant in drawers, cabinets, or loot crates like a Silver Teaspoon or a stray consumable. You get it by killing ARCs and looting their wrecks. It's a combat-gated material, so the fastest route to a full stash of it is fighting the right robots, not sweeping interiors.
Here are the confirmed item stats:
| ARC Coolant stat | Value |
|---|---|
| Rarity | Rare (recyclable) |
| Source | Salvaged from destroyed ARC machines |
| Stack size | 3 |
| Weight | 1 kg |
| Sell value | ~1,000 Raider Coins |
| Recycles into | Chemicals (up to 16, per trackers) |
| Marketplace value | ~40 Seeds (24h median) |
At ~1,000 coins for 1 kg, ARC Coolant is worth the pocket space — a full stack of 3 is roughly 3,000 coins for 3 kg, which is a healthy return for a material you were going to generate anyway by clearing ARCs.
A quick disambiguation: the game has three similarly named items — ARC Coolant, Impure ARC Coolant, and standard Coolant. They are not interchangeable. This guide is about ARC Coolant specifically (the Rare one that salvages from ARCs). If a recipe or Expedition project asks for one of the others, don't assume your ARC Coolant covers it.
Which enemies drop ARC Coolant?
Because ARC Coolant is salvage, the enemy you kill matters. It comes off a range of mid-to-heavy ARC units rather than the little skittering ones. Community trackers most consistently confirm it dropping from:
- Comet
- Queen (the persistent world boss)
- Sentinel
Item databases also list it appearing off the Matriarch, Vaporizer, Surveyor, and roll-type units like the Fireball and Pop. The through-line: the bigger and more mechanically complex the ARC, the more likely its wreck yields coolant. Small trash mobs are a waste of ammo if coolant is your goal — prioritize the heavier spawns.
One important efficiency note: destroying an ARC is what unlocks the salvage. You don't extract coolant from a machine you merely disable or run past — you have to actually kill it and loot the remains. Bring enough sustained damage (or a coordinated squad) to finish heavy units cleanly, because a half-killed Queen that walks away is zero coolant and a lot of wasted resources.
What is the fastest way to farm ARC Coolant?
Two things stack the odds in your favor: where you drop in, and what map condition is active.
1. Go to red danger zones. ARC Coolant is Rare, so like every rare material its density is highest in the high-loot / high-danger areas of each map — the same zones that also spawn the tougher ARCs. Deltia's Gaming and other guide sites all point to the same principle: skip the safe fringe, push the hot pockets where heavy ARCs patrol. Higher risk, but that's where the coolant (and the ARCs that carry it) actually live.
2. Chase electromagnetic storm conditions. This is the single biggest farm accelerator. During an electromagnetic storm map condition, Baron Husk ARCs appear across maps like Blue Gate, Dam Battlegrounds, and Spaceport, and these husks reliably hand over ARC-material salvage — ARC Performance, ARC Flex Rubber, and ARC Coolant among them. If you see an EM storm rolled for the session, that's your cue to farm coolant. (New to conditions? See our ARC Raiders map conditions explained guide for how to read and exploit them.)
| Farm factor | What to do |
|---|---|
| Map | Blue Gate · Dam Battlegrounds · Spaceport |
| Condition | Electromagnetic storm (spawns Baron Husks) |
| Zone | Red danger / high-loot pockets |
| Targets | Comet, Queen, Sentinel, roll-types + Baron Husks |
| Rule | Kill heavy ARCs, then loot the wreck |
3. Run it with a squad. Heavy ARCs melt far faster with focused fire, and coolant farming is a numbers game — more kills per raid means more salvage rolls. Solo is viable in EM-storm husk farming (husks are softer than a Queen), but for boss-tier ARCs a duo or trio dramatically raises your coolant-per-hour.
What is ARC Coolant used for?
ARC Coolant has two jobs: crafting input and recycle stock.
Crafting & upgrades. As a Rare ARC-derived material, ARC Coolant feeds higher-tier recipes and upgrade paths in the Speranza workshop, and it shows up as a requirement in Expedition projects (community trackers have it feeding Expedition cache objectives). If you're chasing Expedition rewards or crafting advanced gear, hold a reserve rather than dumping it all on the market.
Recycling into Chemicals. Break ARC Coolant down at the workshop and it converts into Chemicals — trackers list up to 16 per coolant as the maximum return. Chemicals are a basic material used to craft medical supplies, explosives, and utility items, so if you're short on healing or throwables, recycling coolant is a fast top-up. The catch: you get fewer Raider Coins in value by recycling than by selling the coolant outright.

Should you sell or recycle ARC Coolant?
Here's the decision in one line: sell for coins, recycle for Chemicals.
- Sell it if you want raw coins — at ~1,000 per unit it's a clean payout, and it's a popular market item (~40 Seeds median on the player marketplace).
- Recycle it if you're actively crafting and short on Chemicals for meds, explosives, or utilities — the coin loss is the price of skipping a separate Chemical grind.
- Bank it if you're mid-Expedition and a project wants ARC Coolant directly — don't sell material you're about to need and have to re-farm.
For most players who aren't deep in a crafting project, selling is the higher-value default because you keep full coin value and Chemicals are easy enough to source elsewhere. Only recycle when the Chemicals are worth more to you right now than the coin difference.
Is ARC Coolant worth farming?
Yes — but as a byproduct, not a dedicated grind. ARC Coolant is one of the better "free money" materials in ARC Raiders because you generate it by doing something you were already going to do: killing ARCs. You rarely need to build a whole raid around it. Instead:
- Loot every heavy ARC wreck you pass. At ~1,000 coins each for 1 kg, ignoring a coolant drop is leaving guaranteed value on the ground.
- Treat EM-storm sessions as bonus rounds. When the electromagnetic storm condition is up and Baron Husks are spawning, that's the one time it's worth actively routing toward them — the salvage density (coolant, ARC Performance, ARC Flex Rubber) makes the detour pay.
- Set a personal stack rule. Keep a small reserve (3–6) for Expedition projects and workshop upgrades, then sell everything above that. Coolant sitting in your stash is coins you haven't banked and a target if you die on Topside.
Where it stops being worth it: grinding low-tier ARCs hoping for coolant. Small units drop it rarely if at all, so farming them for coolant burns ammo and time for a poor return. Coolant is a heavy-ARC and husk material — hunt accordingly, or don't hunt it at all and just pick it up as it comes.

FAQ
What is ARC Coolant used for in ARC Raiders? ARC Coolant is a Rare crafting material. It feeds higher-tier workshop recipes and Expedition project requirements, and it can be recycled into Chemicals — the basic material used to craft medical supplies, explosives, and utility items. You can also just sell it for around 1,000 Raider Coins.
How do you get ARC Coolant? You salvage it from destroyed ARC machines — it is not found in loot containers. Kill mid-to-heavy ARCs (Comet, Queen, Sentinel, and roll-types) and loot their wrecks. The fastest source is Baron Husk ARCs during electromagnetic storm conditions on Blue Gate, Dam Battlegrounds, and Spaceport.
Where does ARC Coolant drop the most? In high-loot red danger zones, and especially off Baron Husks during electromagnetic storm map conditions. Those husks reliably drop ARC-material salvage including ARC Coolant, ARC Performance, and ARC Flex Rubber.
Should I recycle or sell ARC Coolant? Sell it if you want coins — recycling returns fewer Raider Coins than an outright sale. Recycle it only when you need the Chemicals for meds, explosives, or utility crafting, or hold it if an active Expedition project requires ARC Coolant directly.
Is ARC Coolant the same as Impure ARC Coolant or Coolant? No. ARC Coolant, Impure ARC Coolant, and standard Coolant are three separate items with different uses. This guide covers the Rare "ARC Coolant" that salvages from ARCs — don't substitute one for another in a recipe or project.
How much does ARC Coolant sell for? Roughly 1,000 Raider Coins per unit, and it stacks to 3 (so about 3,000 coins for a full stack at 3 kg). On the player marketplace it trades around 40 Seeds as a 24-hour median.
