Removing tramp oil is the key to coolant longevity. Tramp oil is a food for bacteria and can emulsify into the coolant. This leads to coolant breakdown which will create more extensive problems. The Snapdragon Coalescer not only separates tramp oils, but it can also remove suspended particles and fight foul odors.
Fluid is pulled from the surface of your sump and goes into the coalescing tank. Tramp oil separation is caused by gravity and is accelerated by using coalescing media. The amount of separation is dependent on how long it is held in the tank. Holding time can be adjusted by setting the air pressure going to the pump, at 1 GPM fluids are held for 20 minutes and at 3 GPM fluids are held just over 6 minutes. When coolant is new it rejects tramp oils quickly.
