Bell & Gossett 138811 GMU60P Glycol Make-Up Unit

Critical infrastructure facilities can evaluate the Bell & Gossett 138811 GMU60P glycol make-up unit with 60-gallon storage, 115 V power, skid-mounted pre-piped construction, Level Logic controls, dry-run protection, and power, low-level, and pump-run indicators.

The unit is intended for closed-loop heating, chilled-water, process, snowmelt, and radiant-heat systems, while the storage tank can serve as a potable-water break tank. Installation requires level support, accessible service space, independently supported discharge piping, leak inspection, and appropriate secondary containment.

System Components

- Sixty-gallon storage capacity establishes the listed reservoir volume for make-up planning.
- 115 V power identifies the electrical supply requirement for control-panel installation.
- Skid-mounted, pre-piped construction affects foundation support and equipment-room access.
- Level Logic controls provide the documented automatic level-management configuration.
- Dry-run protection establishes a specific pump-protection function for operating safeguards.
- Power, low-level, and pump-run indicators support local status monitoring during operation.
- Closed-loop heating and chilled-water service define the primary application context.

Performance and Application

The GMU60P is listed for closed-loop heating, chilled water, process systems, snowmelt, radiant heat, and potable-water break-tank applications. Its storage capacity and controls describe make-up functionality, not guaranteed delivery pressure or flow, so system pressure settings, pump capacity, and fluid requirements require separate verification.

Installation Requirements

Place the unit on a level, secured base with adequate inspection access, support the discharge line independently, provide secondary containment for glycol service, and inspect visible fittings for leaks. Install correctly sized safety, pressure, temperature, flow, and expansion-control devices for the closed system.

Warranty and Maintenance

Bell & Gossett provides an 18-Month Limited Warranty from shipment or a 1-Year Limited Warranty from installation, whichever occurs first, covering defects in materials and workmanship. Proper installation and intended use are required, while misuse, alteration, negligence, and contrary operation are excluded. Mulmotor provides pre-purchase product guidance and order-related customer support.
