Bell & Gossett’s Glycol Make-up Unit (GMU) is an automated 100V diaphragm pump with digital control. Each package is designed to maintain critical minimum pressure levels from 7.5 to 70 psi. Operates as needed to add water or water-glycol solution to a closed-loop heating, chilled water, process, snowmelt or radiant heat system.
The self-priming unit controls fluid pressure with an easy-to-use digital display and immediately notifies the operator if the fluid level drops, which can indicate a leak. A pressure relief valve provides protection from excess pressure.
