Series HL is suited for heating oils used in fluid power and machine lubrication applications. They are designed with low watt densities (approximately 10 W/in2) to allow direct immersion into storage vessels, and they are designed from 0.5 to 12 KW for mounting via 2, 2.5 and 3" NPT screw plugs as well as the company’s 4.5" OD flange. Lube oil heaters are intended for heating oils used in gearboxes and machine lubrication applications. Lube heaters are designed with watt densities of 23 W/in2 for SAE 10-30 oil and 13 W/in2 for SAE 40-50 oil to allow direct immersion into the storage vessel. They can be used to maintain a desired temperature within lubrication oil reservoirs or for compressors, turbines, and lubrication of gears, bearings and machinery.
