Chromalox RSTO and RST Unitary Electric Immersion Heaters provide low watt density heating over a large heated surface with precise temperature control for such materials as asphalt, fuel oil, pitch and tar, liquid sugar, molasses, lube oils, linseed oil and other heat sensitive materials. Unitary heaters are installed in large tanks above or below ground (requires access to one tank end).

RSTO immersion heaters are recommended for general purpose applications and cramped locations. Open coil (OCE) heating elements are housed in 3" Schedule 40 NPS steel pipe and are removable without draining the tank. A liquid-tight adapter box5 is provided for welding the heater assembly to the tank header.

Easy Maintenance and Service — Flexible OCE elements (RSTO Models only) can be bent in a vertical plane on a 12 inch minimum radius and require only 3 feet for installation or removal.

Weather Proof Electrical Enclosure completely wired with safety interlocked circuit breaker, overtemperature controls, pilot lights and switches. Electronic process temperature control mounted in door and accessible from outside the enclosure. Optional time clock.

Optional Explosion Resistant Electrical Enclosures for hazardous locations, special construction material, stainless steel and others.
