About KoolAir Pump

Manufacturers Edge has been in the fluid handling equipment industry for over 40 years. We have seen the evolution of pumps across a wide range of applications, and we have contributed to it.

When our customers started reporting melted marine AC coolant pumps and the problems they caused on the water, we knew there had to be a better solution. The answer was run-dry protection: a pump that could withstand thermal overload when liquid flow stopped.

Our engineering team redesigned the marine AC coolant pump from the ground up. With upgraded materials, tighter tolerances, and extensive testing, we created the KoolAir HVAC Cooling Pump. It was the first marine HVAC coolant pump built to survive a clogged strainer without damage.

Today, KoolAir pumps are installed on vessels across the country. From weekend cruisers to commercial charter boats, our customers count on KoolAir to keep their air conditioning running when it matters most.
