Screwed into tank walls, this UL Listed / CSA Certified direct contact heat source heats liquids, viscous fluids, forced air and gases with maximum energy efficiency. In addition, elements can be bent in many configurations to suit a variety of applications. Most screwplug heaters come with a thermowell (for temperature control sensor) and a completely wired terminal box for electrical connection. Certain models available with a patented 360° rotatable terminal screwplug housing to facilitate easy conduit connections. Select from a wide variety of sheath materials, element lengths, plug sizes and rating from 0.5 kW and up, for 120 to 600 volts.   Circulation Circulation heaters consist of a screwplug or flanged type immersion heater mounted in a thermally insulated heating chamber. Designed to provide high heating efficiency to a flowing medium (liquid, steam, air or gas) by in-line or side-arm operation. Circulation heaters can be designed to withstand pressures to 500 psi and temperatures to 1200°F. Chromalox can provide thermocouple sensors to connect to most controllers or provide on/off bulb & capillary type controls. Complete skid mounted packages with controls are available. Select from many terminal enclosures, sheath and vessel materials, flanged connections and controls. Power ratings range from 1.5 to 2000 kW, with some units meeting UL, CSA, VDE and ASME codes.   Flanged Immersion Flanged Immersion heater construction is similar to the screwplug immersion heater with elements joined to a flange that mates with a matching companion flange in a vessel wall. Ideal for generating steam or heating gases and liquids for use in pressure vessels and tanks. Factory designed with a wide selection of ANSI and custom sized flanges for industrial and OEM applications. Element lengths to 240" long and rated up to 500 kW with watt densities to suit many applications. Chromalox can also rebuild large flanged heaters to save you money. Most units are UL Listed and CSA Certified.   Process Air Process Air heaters include a broad variety of stock and custom designs to heat air or other gases in ducts, autoclaves or ovens. They employ an assembly of sheathed tubular, finned tubular or finned strip elements in various configurations that consistently outperform gas, oil and open coil electric heaters. Process air heaters are available in voltages to 600V, ratings to 3.2 megawatts and application temperatures to 1200°F. Applications include warming, drying, preheating, curing and heat treating. Elements are available separately for use in OEM equipment such as space heaters and computer room conditioning systems.   Over-the-Side Immersion Over-the-side Immersion heaters occupy little workspace, require no tank penetrations, and are easily withdrawn for servicing and replacement. They are immersed within a tank to evenly distribute heat in a variety of applications including acid or alkali solutions. Customize your heater from a wide variety of voltages, sheath materials, kW ratings, shapes, integrated thermostats, element configurations and mounting methods.   Strip/Ring/Disc Strip/Ring/Disc heating elements are rugged and easy to install for heat transfer by conduction or convection to heat liquids, air, gases and surfaces with temperatures to 1500°F and watt densities to 35 W/in2. Common applications include drying, melting, baking and curing. Strip heater sizes range from .5" wide to 2.5" and lengths to 72" long. Heaters bolt or clamp to many surfaces. Nested ring heaters can provide concentrated heat in small areas. Select from many sheath materials, termination styles, operating temperatures, sizes, voltages, wattage ratings and mounting devices.   Large Tank Large tank heaters are pre-engineered packages utilizing metal sheath tubular or ceramic insulated, open coil pipe insert heating components for use in 2" and 3" nominal pipe sizes. Heaters provide low watt density heating for such materials as asphalt, fuel oil, pitch and tar, liquid sugar, molasses, lube oils, linseed oil and other heat sensitive materials. Combining heating components with temperature and power controls and safety cutouts provides a complete tank heating system. Heating elements can be removed without draining tanks for quick service. Special designs for underground tanks are also available. Choose from a wide selection of welded or flanged connections, NEMA type control enclosures, voltages between 208 and 575 volts and ratings as high as 200 kW. Options include special ratings, lengths to 40 feet, replacement parts and back-up controls. Separate insert heaters are also available. Copyright © 2005
