/* Add the suffix “3P” to the model number for 3 phase power. Higher kW ratings are available. Contact OMEGALUX. Consult Section Z for data on
allowable watt densities for more viscous materials.
†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 result in excessive temperatures can create hazardous conditions
which can lead to fire. Not intended for use in hazardous areas. Please Note: This immersion heater should be used with an approved temperature
control device to assure safe operation. See Section P for our selection of process controllers.
1 Heaters with General Purpose Enclosures are UL Listed and CSA Certified.
