Freeze Protection and Temperature Maintenance for Metallic & Non-Metallic Tanks and Vessels

With winter around the corner, manufacturing plants need to consider the possibility of freezing or low process temperatures effecting outdoor storage tanks and transfer vessels. The most common approach is to install electric heating panels on the outer surface of these tanks and vessels to prevent the contents from freezing. Lower than normal ambient temperatures can also have negative effects on the flow of liquids for a given process. In these situations it is important to maintain liquids at a constant temperature. Electric heating panels are easy to install on tanks and vessels and provide the flexibility to heat a large area of the tank surface. They can also be used to target heat to specific areas on a tank.

Hotfoil ELP heating panels are suitable for installation on metallic tanks and vessels for freeze protection or process temperature maintenance up to 79°C/175°F. They incorporate flat foil resistive elements that are laminated by heat and pressure in a multi-layer fiberglass construction with epoxy resin. The resulting electric heater design is a semi-flexible panel that is waterproof and durable. They are used in a variety of heating applications spanning 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 be used in dry, wet, or corrosive environments, are available in 120 and 240 volts, and are approved for hazardous and non-hazardous areas.
