Which Air Cooled Oil Coolers Should be used for Vacuum Pump Oil Cooling?

Air cooled fluid coolers can be used to make an offline cooling circuit to cool a large variety of equipment’s, increase their efficiency & optimize their energy consumption. An offline oil cooling circuit has been regarded as an effective technique to cool fluids. Offline systems also called kidney loops, work by using a pump to draw fluid from the equipment’s reservoir, circulate the fluid through an air cooled oil cooler, and returning the cool fluid back to a reservoir. High temperatures can quickly degrade fluids and at times even produce byproducts that become particulate contamination in the fluid. Incorporating a filter in the circuit may also reduce the contaminants in the fluid.

In lubricated vacuum pumps if the temperature rises beyond the acceptable limit, the capacity of the vacuum pump to suck air reduces. An oil cooler will improve the performance of the vacuum pump, minimize sludge generation & extend the life of the oil seals.

AIR COOLED VACUUM PUMP

Using an external oil cooling mechanism can also help in simplifying the design of the body of the vacuum pump, by reducing or eliminating fins provided on the body of the vacuum pump. These fins increase the surface area required for higher natural heat dissipation to the surrounding ambient air.
