Thermonics Low Temp. Chillers - Glossary G

Gas Chillers

The term Gas Chiller refers to chillers which use Gaseous Heat Transfer Mediums such as Argon, Nitrogen Gas and Air to carry heat away from the process, to be rejected in the refrigeration cycle of the chiller.

Glycol (Ethylene Glycol) (Propylene Glycol)

Glycol Chillers use Heat Transfer Fluid with concentrations of Glycol (Ethylene Glycol or Propylene Glycol) to protect the Evaporator and lines from freezing. Glycol Chillers are used in applications that require rapid achievement of very low temperatures or involve the risk of low line loss, slow line flow or pressure drop. Achieving the correct percentage of glycol is key, as a concentration that is too high can cause significant drop in chiller efficiency and capacity. In applications characterized by contamination/toxicity concerns, Propylene Glycol is preferred for its non-toxicity.
