The J. L. Wingert GL100-2E1-1 Dual Economy 100 Gallon Glycol Feed System with Low Level Control is a high-capacity automatic glycol feed system designed to maintain proper pressure and fluid levels in large commercial and industrial closed-loop heating and cooling systems. Equipped with a durable 100-gallon polyethylene reservoir, dual pump configuration, and integrated low-level control, this system delivers dependable fluid replenishment while helping protect critical equipment from pressure loss, corrosion, and air infiltration. Available from Bypass Feeder, this model is an excellent solution for facilities that require reliable make-up fluid management and continuous system operation.
Large HVAC and process water systems require consistent pressure and fluid volume to operate efficiently. The GL100-2E1-1 automatically replenishes glycol or water whenever pressure drops, reducing manual maintenance while helping maintain peak system performance.
✔ Large 100-gallon storage capacity
✔ Dual pump configuration for increased reliability
✔ Automatic make-up fluid replenishment
✔ Integrated low-level control protection
✔ Reduces the risk of air entering the system
✔ Helps minimize corrosion and equipment wear
✔ Ideal for commercial and industrial facilities
✔ Heavy-duty construction for long service life
The durable polyethylene tank stores a large volume of glycol solution or make-up water, making it ideal for facilities with extensive closed-loop systems and higher fluid demands.
The dual pump arrangement provides increased operational reliability and system redundancy. If one pump requires maintenance, the second pump helps maintain continuous operation, minimizing downtime.
The system continuously monitors pressure conditions and automatically delivers fluid whenever system pressure drops below the desired operating range.
Built-in low-level protection alerts operators when reservoir fluid levels become low, helping prevent pump damage and ensuring safe operation.
Designed by J. L. Wingert for demanding commercial and industrial environments, the GL100-2E1-1 is engineered for dependable, long-term performance.

The GL100-2E1-1 is the preferred choice for facilities requiring greater storage capacity, enhanced reliability, and continuous operation through its dual-pump design.
The GL100-2E1-1 continuously monitors the pressure within a closed-loop heating or cooling system. When system pressure decreases due to fluid loss, maintenance, or temperature-related expansion and contraction, the unit automatically pumps glycol solution or make-up water into the system to restore proper operating pressure.
Its dual-pump configuration provides additional operational reliability, making it especially suitable for mission-critical facilities where uninterrupted system performance is essential.

The system automatically maintains fluid levels and operating pressure in closed-loop heating and cooling systems by supplying glycol solution or make-up water whenever needed.
The dual-pump design provides increased reliability and redundancy, helping maintain continuous operation if one pump requires servicing or maintenance.
The GL100-2E1-1 is suitable for hydronic heating systems, chilled water systems, process cooling applications, district energy systems, and other commercial or industrial closed-loop installations.
The low-level control monitors reservoir fluid levels and alerts operators when the tank requires refilling, helping protect pumps from running dry.
Yes. The larger reservoir reduces refill frequency and is ideal for facilities with extensive piping networks or higher make-up fluid requirements.
