HeetSheet tank heating units are constructed of 26-gage type 304 stainless steel, conforming to ASTM A240. The welded waffle style pattern provides multiple flow paths reducing risk of blockage possible with single-flow designs. For temperatures up to 190°C (375°F), Thermon NH non-hardening heat transfer compound is factory applied to the surface of the HeetSheet unit that contacts the tank wall. This is to eliminate air gaps and optimize heat transfer. HeetSheet units are available in multiple sizes and are pre-rolled to conform to the radius of the tank. Stainless steel tubing connections are provided for steam or other heating or cooling media. Customer supplied fittings are used to connect the inlet and outlet tubes to ThermoTube® pre-insulated supply and return tubing. ThermoTube is arranged separately.

HeetSheet-X Heavy Gage tank heating units are comprised of two sheets of 20-gage, type 304 stainless steel, conforming to ASTM A240. The stainless steel sheets are continuously seam welded together along an outer continuous perimeter with interrupted seam welds arranged inside the perimeter. The welded unit provides multiple flow paths reducing the risks of internal blockage possible with single-flow designs. For operating temperatures up to 191°C (375°F), a factory applied non-hardening heat transfer compound is applied to the surface of the HeetSheet unit that contacts the tank wall to eliminate air gaps and optimize heat transfer. For temperatures above 191°C (375°F), T-75 heat transfer compound 1 may be applied to the HeetSheet units in the field just prior to the units being attached to the tank wall

The RT FlexiPanel is a self-contained, high performance flexible heating panel designed specifically for use on metallic tanks or vessels. Designed to provide heat outputs at 2 watts per square inch (3,100 watts per square meter) or less, the RT FlexiPanel distributes heat evenly over the entire panel surface. 1 The low profile flexible design of the panel permits rapid, trouble free installation using the mounting kit available from Thermon. To ensure multiple flow paths for electrical current to pass, the RT FlexiPanel utilizes a parallel circuit design based on a stamped high temperature alloy heating element. This design eliminates the burnout potential common with series wire-based designs. The rugged construction of the RT FlexiPanel includes a tough metal jacket that provides mechanical protection during handling and installation. The panel's heating element is further protected from vibration and moisture by sandwiching it in a heat-laminated layer of silicone rubber that provides cushion and a watertight seal

The RTF FlexiPanel is a self-contained, high performance flexible heating panel designed specifically for use on fiberglass and plastic tanks or vessels and for metallic tanks and vessels containing high viscosity or temperature-sensitive fluids. Designed to provide heat outputs at 1,085 watts per square meter (0.7 watts per square inch) or less, the RTF FlexiPanel distributes heat evenly over the entire panel surface to maintain stable temperatures.
