APPLICATIONS Heating medium viscosity oil — Suitable for heating medium bodied
oils such as industrial gear oils or numbers 4 and 5 residual fuel oils.
Heating provides low ambient temperature protection, ensuring
that oil remains fluid to lubricate effectively and reduce load on gear
motor drives.
Please Note: This integral thermostat functions as a temperature control only. This is not a fail safe device. An
approved pressure and/or temperature limit control should be used with these heaters to assure safe operation.
See Section P for our selection of controllers.

†Caution: Explosion resistant type E2 construction refers to heater design features which provide explosion resisting containment of electrical
wiring according to National Electric Code. Abnormal application or use of heaters which in excessive temperatures can create hazardous
conditions which can lead to fire Consult Section Z for data on allowable watt densities for more viscous materials.
