Product Description
The Bell & Gossett GMU30 Glycol Make-Up Unit (138808) is a premium system designed to maintain consistent pressure and glycol levels in closed-loop hydronic heating, chilled water, and process systems. It is an ideal solution for snowmelt and radiant heating applications and can also serve as a break tank for potable water systems.
Engineered for reliability and efficiency, the GMU30 operates fully automatically with a pressure switch to control glycol addition and includes a low-level alarm contact for added safety. Featuring a durable build, it supports custom configurations such as duplex setups, a 100-gallon tank option, and compatibility with three-phase input power. The unit is easy to integrate with a 115/1/60 single power connection and a 3/4" NPT system piping connection.
