Temperature stability is essential in a heat transfer system. Consult this collection of heat transfer fluids to find those that will benefit your process.

Corrosion-Resistant Fluid

Designed to protect brass, copper, steel, cast iron, aluminum and other metals used in cooling and heating systems, Jeffcool coolants and heat transfer fluids contain corrosion inhibitors that attach to metal surfaces to passivate them. The ethylene glycol- and propylene glycol-based fluids can be used for process cooling.
