Heat Transfer Fluids

The Kilfrost range of Heat Transfer Fluids covers a wide range of applications. Glycol based, they are used to effectively absorb and transfer heat in both secondary refrigerant and renewable energy applications. The product range benefits from over 75 years experience in inhibiting glycols for safety critical applications.

All of our products offer excellent freeze protection and inhibit against corrosion, bacterial growth and scaling. 



Cooltrans is a range of inhibited heat transfer fluids developed specifically for secondary refrigerant applications in both process/space cooling and temperature regulation.

Cooltrans is a Monoethylene Glycol (MEG) based fluid for use in industrial cooling applications.

Cooltrans Plus is a Monopropylene Glycol (MPG) based fluid and being non toxic and non hazardous is ideal for food and drink applications.

Cooltrans Sustain is a Bio-Glycol based fluid derived from a sustainable source. As well as being non toxic and non hazardous for food applications, it also increases pump efficiency through its low viscosity.
