Glycol Make-Up Units

Glycol make-up units are designed to maintain minimum pressure levels in systems that may have small leaks.  The systems are completely automatic and operate as needed to add water or water-glycol solution to a closed loop heating, chilled water, snowmelt, or radiant heat system.  The water-glycol solution is contained in a polyethylene holding tank and a pressure switch controls the flow of glycol solution to the system.  A low level alarm safety switch safely shuts down the pump when the solution drops to the minimum fill level.

We offer several styles of make-up systems, shown below.  We are also able to engineer custom glycol units to meet any specific needs you may have.
