Yes, a water chilling unit (mechanical refrigeration) can be used to cool our Dielectric Coolants. The flow rate will be slightly lower, due to the difference in viscosity. Before using a unit made to chill water, please check our Material Compatibility Guide
to be sure that the gaskets and O-rings are compatible. Viton / FMK is always the best choice for O-rings and gaskets when using our Dielectric Coolants.
