Blending Coolants & De-Icing Fluids

Fox Liquid Eductor for Coolants

Industrial and vehicle coolants are always a blended mixture of water, ethylene glycol, propylene glycol, glycerin, and various additives. Manufacture of these blended solutions can be accomplished on a continuous basis using liquid/liquid eductors, see schematic below. Please note that a Fox liquid eductors can have multiple suction ports for the simultaneous injection of multiple components or additives. 

When the additive flow rate is below 2% of the main flow, Fox’s unique venturi injector syphon can be used.

Deicing fluids come in a variety of types, and are typically composed of ethylene glycol (EG) or propylene glycol (PG,) along with other ingredients such as thickening agents, surfactants (wetting agents), corrosion inhibitors, colors, and UV-sensitive dye. Liquid eductors can be used to create these blended solutions.
