Thermon Heating Systems

Immersion Heaters

Thermon immersion heaters are commonly used in tank and pressure vessel heating applications, where there is a requirement to maintain liquid temperature to a certain controlled set point. Thermon has many different configurations and can build to custom requirements.

The Caloritech™ FPH Flanged Pipe Insert Heater (also known as an insert tank heater) is uniquely designed to heat storage tanks containing viscous, corrosive or heat sensitive materials including asphalt, tar, fuel, oils, paint and glue.
The FPH provides a safe, cost-effective low maintenance solution for tank heating. By enclosing the heating elements within a sealed pipe insert, elements do not come in direct contact with the heated product and elements can be removed for servicing while the tank and its contents remain in service.

Caloritech™ CX Domestic Immersion Heaters were developed as high quality replacements for the most commonly used heater types. The CXC is available in a range of styles, including 2.5" (64 mm) square flange with tinned copper sheath, 1" (25 mm) tapered brass plug with copper sheath, 1" (25 mm) non-tapered brass plug with copper sheath and round flange with zinc plated copper sheath. The CXI is available with a 2.5" (64 mm) square flange with Incoloy® sheath. Elements are epoxy-coated to protect the heater from moisture and other contaminants that can lead to premature element failure.

Electric immersion heaters are commonly used in tank and pressure vessel heating applications, where there is a requirement to maintain liquid temperature to a certain controlled set point. Typical applications include: antifreeze protection on refueling water storage tanks, oil tanks, fuel-oil tanks, diesel tanks, water tanks, vaporizing vessels and others. Immersion heaters are designed and manufactured in accordance with ASME Section III, Class 1, 2 or 3 and stamped NPT according to code requirements. Immersion heaters also are designed and manufactured under ASME Section VIII, Div. 1 for non nuclear code applications.
