Unitary Immersion (RSTO) Heaters

Immersion Heater And Circulation Heaters - Unitary Immersion (RSTO) Heaters

Chromalox® RSTO unitary electric immersion systems provide low watt-density heating for viscous materials such as asphalt, fuel oil, pitch and tar, liquid sugar, molasses, lube oils, linseed oil, and other heat-sensitive materials.

Unitary Immersion (RSTO) Heaters

Chromalox® RSTO unitary electric immersion systems provide low watt-density heating for viscous materials such as asphalt, fuel oil, pitch and tar, liquid sugar, molasses, lube oils, linseed oil, and other heat-sensitive materials. They can be installed in above-ground tanks. RSTO heater systems with open-coil-element (OCE) heaters are recommended for cramped locations because the opencoil heating elements can be bent in a vertical plane on a 12-inch (305-millimeter) minimum radius and require only 3 feet (1 meter) for installation or removal. The heating elements are inserted into an assembly of 3-inch Schedule 40 NPS carbon steel or stainless steel pipes. The heaters are self-contained with built-in temperature and power controls mounted in a weatherproof electrical enclosure. A liquid-tight adapter box is provided for welding the heater assembly to the tank header.

Applications:

• Asphalt tanks
• Fuel oil tanks
• Pitch and tar tanks
• Liquid sugar and molasses tanks
• Mineral oil tanks
• Linseed oil tanks
• Other viscous material tanks.
