ATS’ iM Series Chillers

Immersion Chiller

ATS’ iM Series chillers, the ATS-Chill iM201, ATS-Chill iM202 and ATS-Chill iM402 are used to remove heat from a fluid tank with a high degree of flexibility and efficiency. The evaporator that is supported with a flexible hose is simply submerged into the fluid tank for heat extraction by the self-contained vapor compression system.


  • Ability to go to -20°C or lower with IM402
  • Use of standard refrigeration cycle for effective heat removal
  • 1.6m long evaporator hose, allows for ease of access and its insertion to liquid tank
  • Front Panel PID displays temperature and has easy-to-use system controls
