Tank Heating
Raychem tank heaters provide a superior heating solution for maintaining the temperature industrial storage tank contents. Ice buildup can cause problems such as unwanted or uncontrolled movement or elevation of the tank. Our solutions work on all types of large diameter storage tanks including:
- Above Ground Tanks
- Underground Tanks
- Above Ground Tanks with Ground Fill to Top
- Tanks with load bearing thermal insulation (usually Foamglas) supporting the tank
Self-Regulating Heating Cables
Self-regulating heating cables provide the solution to freeze protection and process-temperature maintenance applications. The heating cables are avilable in a wide range of watt outputs and voltages to accommodate project specifications.
BTV: The BTV family of Raychem self-regulating heating cables provides the solution to freeze-protection and process-temperature maintenance applications. BTV heating cables maintain process temperatures up to 150°F and can withstand intermittent exposure to temperatures up to 185°F .
The heating cables are configured for use in non-hazardous and hazardous (classified) locations, including areas where corrosives may be present.
QTVR: The QTVR family of Raychem self-regulating heating cables is designed for pipe heat tracing in industrial applications. QTVR heating cables can provide process-temperature maintenance up to 225°F and can also be used for freeze protection in systems having high heat loss. The heating cables are configured for use in non-hazardous and hazardous (classified) locations, including areas where corrosives may be present.
XTV: The XTV family of Raychem self-regulating heating cables provides solutions for industrial freeze protection and process-temperature maintenance applications requiring high power output. XTV heating cables can withstand temperatures up to 420°F and provide process temperature maintenance to 250°F.
The heating cables are configured for use in non-hazardous and hazardous (classified) locations, including areas where corrosives may be present.
Mineral Insulated Heating Cables
Pyrotenax™ XMI Cable
XMI-A (Alloy, 825) electric heat trace cable is a metal sheathed, mineral insulated (MI) cable designed to provide heat tracing solutions for a variety of industrial applications. MI heat trace cable is often used where high power output, high exposure temperatures, or extreme resistance to environmental corrosives is needed. Typical applications include: Pipe Freeze Protection, Process Temperature Maintenance, Longline Heating. Raychem XMI-A MI electric heat trace cables can provide up to 61 watts per foot (200 watts per meter) of power output with area classification and design approvals. The maximum maintain temperature for MI heat trace cable is 1022°F (550°C) and the maximum exposure temperature for the heating cable is 1200°F (650°C).
Power-Limiting Heating Cables
Raychem® VPL
Power-Limiting Cables are used for applications requiring high power output or exceed the temperature ranges of self-regulating cables. VPL can be used for freeze protection and process-temperature maintenance requiring high power output and/or high temperature exposure.
VPL can provide process-temperature maintenance up to 455°F and can withstand routine steam purges and temperature excursions to 500°F with power off. VPL cables are approved for use in non-hazardous and hazardous locations.
Tank Heating Pads
Raychem® RHS
Tank heating pads are designed for applications ranging from freeze protection to process-temperature maintenance of tanks. Raychem offers RHS tank heating pads with two power densities, making them ideal for metal tanks (lined and unlined) and plastic tanks. Factory Mutual (FM) and the Canadian Standards Association (CSA) have approved RHS tank heating pads for use in both non-hazardous and hazardous locations. RHS-L may be used on tank walls capable of up to 185°F, and RHS-H may be used on tanks with walls capable of 280°F. RHS is offered with two power densities (-L and -H).

Applied Products TPG can design the most optimized Tank Heating system for you by applying thermal analyses modeling and optimized heating technology. In the design we take several parameters into consideration, including:
- Tank heating requirements to maintain the fluid temperature
- Heating system characteristics and heating element spacing underneath the tank
- Bottom insulation thickness and thermal conductivity
- Project specific requirements
