Technical & Case Studies

Advances in Chiller Glycol

Coolflow DTX represents a major advance in the field of non-toxic chiller glycol, providing a genuine opportunity to reduce energy consumption and subsequently greenhouse emissions. Until 2009 the only non-toxic glycol available to designers of glycol based chiller systems was propylene glycol, as ethylene glycol is toxic. Propylene glycol has several operational drawbacks compared with ethylene glycol, specifically; ... Read More
