The perfect solution to the problem for maximum heating performance in non-hazardous and non-corrosive environments.
Hazardous locations are those areas where a potential for explosion and fire exists due to the presence of flammable gases, vapors, pulverized dusts or ignitable fibers in the atmosphere. Hazardous locations are created from the normal processing of volatile chemicals, gases, coal, grains, etc., or from the accidental failure of storage systems for these materials.
Heatrex tubular and finned tubular elements provide a highly efficient, reliable and cost effective means of supplying heat directly to air, various types of liquids and metals.
Construction:
- Nickel-chromium resistance wire is uniformly stretched and imbedded into magnesium-oxide powder.
- Resistance wire is accurately centered within a copper, steel or alloy sheath.
- Terminal pins are attached to the resistance coil at each end to create an unheated zone near the terminals.
Heatrex has electric immersion heaters including screw plug immersion heaters, flange immersion heaters, over-the-side immersion heaters, csa listed explosion-proof immersion heaters, electric immersion heater control panels, electric immersion heater thermostats and accessories, and tank heaters.
Enclosure Heaters/Switchgear Space Heaters are designed to maintain temperature and minimize moisture inside electrical and mechanical equipment enclosures. They conveniently replace strip heaters or other less efficient heating devices.
ON/OFF process temperature control is recommended for less demanding applications. Systems with two or more heating stages utilize an INDEECO Controls electronic sequencer (step controller), driven by an analog output PID temperature controller to minimize the amount of load cycling while providing good outlet temperature control.
A fully proportional SCR control system with PID temperature control is recommended for industrial heating applications which must accommodate material flow changes and provide the highest degree of accuracy for outlet temperature control.
Heatrex has ciculation heaters and circulation heater control panels for all your needs.
From transport refrigeration to walk in cooling units, Heatrex can meet your defrosting requirements.
Heatrex Bolt Heaters are used to preheat large, hollow holding bolts or studs where a high concentration of heat is critical for bolt expansion in a short period of time. As an insertion type unit, the bolt heater is widely used in the manufacture and servicing of heavy duty steam or other pressure equipment. It is also used to heat die blocks and large platens and to expand adjusting bolts on mechanical or hydraulic presses.
A TraceFREE Impedance Pipe Heating System is a unique, safe, and proven method for electric pipeline tracing and heating. The pipe actually becomes the heating element when low AC voltage is applied to it by a special, custom-designed transformer.
