KoolAir Pump is less expensive than a comparable marine a/c coolant pump without ‘dry run protection’. The performance and quality is equal - parts are even interchangeable - but only KoolAir provides the exclusive added value of ‘run dry protection’ and the peace of mind it delivers.
Our engineers designed KoolAir specifically to withstand the higher temperatures reached when liquid is not flowing, and, in fact, the KoolAir pump will run several hours before shutting itself down without damage. After reintroducing water, you simply wait for the pump to cool on its own (or hose it down) and it will resume operating normally.
And so can you.
