Rugged, deployable cooling for radar, electronic warfare systems, vehicle powertrain testing, and weapons systems testing.
View Recommended ChillersMilitary applications demand extreme reliability and rapid deployment in austere environments. Radar systems generate 500+ kW of heat in compact packages that the chiller must remove to maintain availability; EW testing needs stable cooling for test equipment; vehicle powertrains are tested in controlled thermal chambers; weapons testing requires rapid thermal cycling.
In the field, chiller downtime means mission failure — reliability and serviceability are not features, they’re requirements.
Common process cooling problems in Military & Defense and why getting the chiller right matters.
Cooling must function from 60°C desert to −40°C arctic, at altitude, with unreliable power and water. The chiller must be transportable, tolerate poor line quality, and need minimal infrastructure.
Military operations can’t wait for repairs. High MTBF, field-serviceable swap-out modules, and redundant cooling with automatic switchover are mandatory.
Equipment faces dust, salt air, and thermal shock from rapid ambient swings. Sealed, epoxy-coated, stainless hardware is required; standard industrial chillers corrode quickly.
Our chillers integrate directly with the process equipment that Military and Defense relies on. These are the systems we most often cool — each with its own temperature target, flow, and failure mode we size for.
The chiller cools high-power transmit/receive subsystems.
The chiller removes the heat load that limits beam-on time.
The chiller drives the cold extreme of ruggedization testing.

Radar chiller failure in theater shuts down the system, losing intelligence capability and compromising tactical advantage and personnel safety, with field repair stretching 2–4 weeks. EW lab cooling loss suspends testing and slips weapons development by months. Vehicle powertrain test cooling failure invalidates durability testing, forcing revalidation that adds 6–12 months and $10M+ in sunk cost.

Whether you're researching options or ready to order, AG Chill can help.
Military equipment engineers and program managers at defense contractors researching radar cooling, EW thermal management, and military-grade chillers.
Chief engineers and logistics managers evaluating cooling for weapons development or field deployment — needs MIL-STD compliance, deployment logistics, and supply-chain security.
Program managers and contracting officers approving project cooling. Need ITAR compliance, defense-budget-aligned pricing, military tech support, and delivery matching the program phase.
Military cooling is dominated by prime contractors and premium MIL-spec suppliers. AG Chill (a US company) competes on value and availability.
Defense prime contractors have deep combat-cooling expertise but very high cost and limited availability outside prime contracts. AG Chill captures the contractor supply chain and specialty applications.
Specialty military chiller makers military-grade units are MIL-spec compliant but at a 30–50% premium with long lead times. AG Chill’s value positioning appeals to cost-conscious programs.
Ruggedized industrial OEMs offer hardening but aren’t optimized for combat scenarios, with limited MIL-spec documentation. AG Chill’s military-focused design provides confidence.
European allied suppliers add interoperability and export-control complications. AG Chill, as a US company, avoids those.
