Neptune™ Glycol Feeders are designed for the addition of glycol solution to closed-loop chilled or hot water systems to maintain pressure in the loop by making up for losses that occur due to leakage.

Glycol addition is controlled by a pressure switch with adjustable low and high set points. When the pressure in the loop reaches the low set point, the pump begins to feed glycol into the system until the high-pressure set point is achieved and the switch stops the pump.

GE-50-1: Economy version including 1.0 gpm at 40 psi (3.8 L/min at 2.8 bar) pump
G-50-1: Complete system including 1.5 gpm at 100 psi (5.7 L/min at 6.9 bar) pump and low-level light.
G-50-1A: Complete system including 1.5 gpm at 100 psi (5.7 L/min at 6.9 bar) pump, low level light and audible alarm.
G-50-2A: Complete system including two 1.5 gpm at 100 psi (5.7 L/min at 6.9 bar) pumps, low level light and audible alarm. Separate discharge and pressure switches allow feeding two separate closed-loop systems independently from a single tank.
