glycolAutomatically adds glycol solution to make up for leakage in closed loop water systems. Neptune Glycol Feeders are designed for the addition of glycol solution to closed loop chilled or hot water systems. The system automatically maintains pressure in the loop by adding glycol solution to make up for losses which occur due to leakage.

Glycol addition is controlled by a pressure switch with adjustable low and high set points.

Standard Pressure Switch:
Cut-In Range: 10-45 PSI Cut-Out Range: 20-60 PSI
Adjustable Differential: 10-30 PSI
Other pressure switches available.

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 stops the pump.
