FM Approved Silicone Rubber Heaters for Tank and Vessel Heating

Silicone rubber electric heating element for tank and vessel heating.

Silicone rubber electric heating elements are well proven, tried and tested flexible heaters for heating plastic or metallic tanks and vessels. Their low mass offers virtually no thermal inertia and within minutes can achieve elevated temperatures. They are generally easy to apply to the surface of tanks, chutes, or hoppers and can be custom designed in virtually any shape, all that is required is a sketch of the heated area and information about the electrical connections.

Silicone rubber electric heating elements are constructed by vulcanizing a nichrome heating element to the silicone rubber layer to produce a homogenous laminate. Two layers of 0.028” thick silicone rubber compound, sheath cured on one side, are calendared with high strength fiberglass mesh and vulcanized together under heat and pressure. This bonding sandwiches the resistance heating element between the two layers. An electric grounding mesh is located on the assembly and a further layer of silicone rubber is applied and vulcanized, making a homogenous assembly.

The heaters are used primarily for metallic and non-metallic tank and vessel heating. Their flexibility, both physically and design-wise, allow the heaters to be used for a wide variety of applications. Silicone rubber heaters are water-resistant and may be used for outdoor or “wet” applications, as long as the thermal insulation or exterior covering over the heaters is weatherproofed.

Silicone rubber heating systems must be correctly temperature controlled. The controls and all electrical components must be approved for the area as classified. All wiring must follow Federal, State and Local codes and be fully compliant with the NEC as it relates to the project. If in doubt, please contact an industrial heating applications expert for assistance.

Epoxy Laminated Panels for Industrial Tank Heating

Epoxy laminated heater for tanks

Need a way to maintain process temperature for a holding tank? Looking for something easy to install and connect? Consider an epoxy laminated electric heating panel.

These heaters use a flat foil resistive element which is laminated in a multi-layer fiberglass construction using epoxy resin. The manufacturing process is done under tightly controlled heat and pressure to assure bonding and structural integrity.  The resulting electric heater design is a semi-flexible panel that is waterproof and durable.

Epoxy laminated panel (ELPs) are a very versatile option for tank heating. ELP heating panels can be used in a variety of applications from freeze protection to process heating with exposure temperatures ranging from -40 F to +212 F. ELP heating panels can be used on either vertical or horizontal tanks with diameters of 48" and above, with either metallic or non-metallic construction. They can also be used in dry, wet, or corrosive environments, as well as for hazardous and non-hazardous areas.

They are quick and easy to install and require no special tools or skills. Heaters are usually installed by banding them to the tank with metal bands or polyester straps, which takes only a matter of minutes. After installing the heating panels, adhesive aluminum tape should be applied to the edges of the heaters acting as a seal. This will prevent thermal insulation becoming trapped between the heating panels and the tank.

The heaters provide a low watt density heating profile, and along with their inherent low mass,  ELPs provide excellent thermodynamic performance.
