Welcome and thank you for your interest in the Militaries #1 choice for cleaning oil coolers. We are the only patented flushing system in the world that will remove 99.99% of debris, varnish and other damaging materials from oil coolers and lines

Why hot flush...

Whether it's a fighter jet, a helicopter, a Humvee or a tank it has an oil cooler. If there is an engine, transmission, or hydraulic failure that can contaminate the oil cooling system the debris is trapped causing premature failure and will drastically reduce vehicle readiness and field life.

Many times coolers and cooler lines get overlooked, because most people don't understand the intricacies of them. A lot of technicians have never seen the inside of a cooler. Today’s coolers make for wonderful heat exchangers, but to do that they end up with thousands of little "traps" for debris to get caught in. Oil molecules do not conduct heat amongst themselves efficiently, but they do conduct well with metal. So the cooler manufacturers must design coolers that makes the oil molecules make contact with metal as much as possible. This leaves us with coolers that contain many various "weave" or "honeycomb" type patterns.

Hot Flush is used by many branches of the Government, including tank remanufacturing centers and helicopter maintenance depots. Hot Flush has 190 degree heated oil, checkable 10 micron filtration (finer filtration options available), a flow meter, and a long lasting stainless steel cabinet, but it's our high-speed reversing that is the key to our success. Being able to instantly reverse the direction of flow every three second for one quarter of a second creates immense scrubbing energy in the cooler that no one can match.

Typically the heat exchanger gets flushed of some of the loose debris with a cold solvent or fluid flusher. When the cooler is returned back to normal operating temperatures, the metal expands again releasing the debris that was bound in the cooler.

Hot Flush is not limited to oil cooler cleaning Hot Flush's state of the art technology is being used to clean fuel heaters on theT700 engines.

Hot Flush has been proven to be the most effective and efficient way to clean heat exchangers on turbine engine heat exchangers.
