Filling a closed loop system with heat transfer fluid is easy with this fill valve. It allows you to flush the fluid through the loop continuously using the included drill pump. The continuous flush assures that no pockets of air remain in the system. No air means that your system will run at peak efficiency and the glycol will last longer. With this filling your closed loop system properly only takes a few minutes.

Includes:

Complete Fill Valve Body with three Full Port Ball Valves
Power Drill operated pump
Adapter for 1/2" hose
Two 2ft. pieces of 1/2" braided nylon hose (not shown in picture)

All you need to have is the power drill (corded or cordless), a bucket, and the Glycol to fill your system.

So far the unit is doing good for one of our houseless individuals in our community. The sun doesn’t always shine thru the trees in his camp but it’s light enough to carry into town to it charged. He’s using it to run his CPAP at nighttime
