Chromalox® also offers an extensive thru-the-side immersion heaters from 3” up to 14” flange immersion with screwplug immersion sizes from ½” to 2 ½” NPT in copper, steel, 304 SS and Incoloy® materials.
Over-the-side heaters for: plating, acids tanks, clean water, De-ionized, corrosive solution tank and demineralized water application immersion heaters. These elements can be manufacturer with special sheath materials of Quartz, fluoropolymer, ceramic, cast iron, titanium, Incoloy®, as well as standard copper, steel and stainless steel.
Inline circulation, air duct type heaters for air or gas heating, and non contact radiant, including pipe and tank heat tracing, convection and blower comfort and packaged systems with steam boilers, vaporizer, large tank & open coil and fluid heat transfer systems.
Chromalox® provides state of the art microprocessor based controls that provides both the temperature and power controls to operate electric heaters. These DIN style microprocessor controls incorporate Auto-tuning, ramp-soak, Smarter Logic®, CE certified and bumpless transfer in single or multiloop control designs. The MaxPac® series offers “touch-safe” SCR designs in three phase and single phase SCR versions in either, zero-cross over or phase angle fired firing modes.. Chromalox’s exclusive DOT (Demand Oriented Transfer) firing switches the fewest number of cycles to provide the most precise zero crossover control.

Ogden Manufacturing specializes in the plastics heating market with their band heaters including the Mighty-Miser® insulated ceramic, the Aluma-Flex® cast aluminum, the Mighty-Tuff® high watt density, high temperature band as well as the traditional Mica band for extruder or injection molding heating requirement.

Ogden has insertion heaters featuring a “Split” sheath SST and a “Quad” QST tubular designed especially for platen, die or mold heating applications where the holes are poorly drilled or worn through age. The Ogden Maxi-Zone® heater provides multi-zone heating for continuous process temperatures up to 2000F and where up to three independently controllable areas along the sheath length can be achieved. The more traditional Bullet® and Might Watt® cartridge heaters complete the insertion heater products.
Immersion heaters including the Mighty-Blade® which is a flat blade tubular process heater along with a special SiAION ceramic tubing used in heating molten metal baths, corrosive service, vacuum and other extreme temperature applications up to 2100F.

Thermo Systems Techology provides “Skin Effect” pipe heating and “impedance” heating for pipe-line heating solutions.
