Arc Raiders players chasing Expedition milestones have hit a snag: Cooling Coils, usually overlooked as low-value loot, are now a critical requirement for the second stage of the second Expedition. Unlike most scavenged materials, these don’t spawn in abundance, forcing players to methodically search high-yield zones. The good news? They cluster in predictable locations—if you know where to look.
Unlike other recyclables, Cooling Coils don’t appear in random crates. They’re tucked into red lockers, breachable industrial crates, and toolboxes—almost always in Industrial areas. Dam Battlegrounds remains the most reliable map for securing them, with three hotspots offering the highest density
- Hydroponic Dome Complex: Compact and packed with loot, this dome’s red lockers frequently yield Coils.
- Water Treatment Control: A mid-sized facility with multiple crates, often overlooked but consistently stocked.
- Power Generation Complex: The largest of the three, with enough containers to justify a dedicated sweep.
Beyond Dam Battlegrounds, Spaceport’s Industrial zones—particularly Rocket Assembly—host a surprising number of Coils. The first and second floors of this facility are lined with red lockers, while adjacent areas like Container Storage and Vehicle Maintenance occasionally drop them in breachable crates. Players who’ve scoured these zones report a 30–40% success rate per visit, making them a viable secondary option.
Why the focus on these areas? Cooling Coils aren’t just Expedition grinds; they’re rare enough that selling them nets a paltry 1,000 coins—barely worth the effort unless you’re salvaging for six chemicals and two Steel Springs. For most, their only value lies in Expedition completion. Pro tip: Prioritize Dam Battlegrounds first. If you’re still short after two runs, Spaceport’s Rocket Assembly becomes the next logical step.
One final note: Cooling Coils don’t respawn instantly. Clear an area of them, and you’ll need to return later—or switch maps entirely—to find fresh drops. Patience pays off, but efficiency is key when Expedition deadlines loom.
