All ATC Chillers are suitable for use with sterile deionised water or Propylene Glycol solutions. ATC recommend the use of Hexid A4. Other antifreeze or inhibitors are not recommended as these may corrode your application and damage the K series chiller seals. Please check with your application manufacturer for material compatibility data.
Other heat transfer fluids can be specified when ordering your chiller (for example oils or HFE fluids).
