Overview
Chromalox tank heaters are pre-engineered packages employing metal-sheath tubular or ceramic-insulated, open-coil pipe insert heating components for use in 2- and 3-inch nominal pipe sizes. This unique construction allows heating elements to be changed without draining the tank. These heating components can be combined with temperature and power controls and safety cutouts for a complete tank heating system. Chromalox tank heaters are well-suited for applications in the chemical/petrochemical industry, including bulk oil storage and asphalt heating. NEMA-type control enclosures are available. Options include special ratings, lengths to 40 feet, replacement parts, and back-up controls. Separate insert heaters are also available.
Products
LTFX heaters provide low-watt-density heating over a large surface area while providing precise temperature control for such materials as fire water storage, asphalt, diesel lube oils, ethanol, biodiesel fuel, glycerin, animal fats, vegetable oils, fuel oils, or similar types of liquids.
Chromalox OCE open coil element large-tank electric heaters installed inside 2- or 3-inch Schedule 40 NPS pipe provide uniform heat over a large surface area.
Chromalox FXTH flexible tank heaters provide low-watt-density heating for viscous materials such as asphalt, fuel oil, pitch and tar, liquid sugar, molasses, lube oils, linseed oil, and other heat-sensitive materials.
Chromalox RSTO and RST unitary electric immersion systems provide low-watt density heating for viscous materials such as asphalt, fuel oil, pitch and tar, liquid sugar, molasses, lube oils, linseed oil, and other heat-sensitive materials.
An optional Chromalox NEMA 4 weatherproof or NEMA 12 oil- and dust-tight electrical control center is available completely wired with indicating electronic process control, fail-safe overtemperature controls, master circuit breaker, contactors, fuses, pilot lights, switches, and control transformer.
Heating of viscous materials, in large storage tanks, to pumping temperatures. Maintaining an entire tank of viscous fluids such as fuel oil or asphalt at pumping temperatures is very costly. In many applications it is not pratical or economical because the tanks are located underground or are not insulated.
