Process Air Heaters

Process air heaters in stock and custom designs are employed in heatingair or other gases in
ducts, autoclaves, or ovens. Sheathed tubular, finned tubular, and finned strip elements
consistently outperform gas, oil, and open-coil electric units in both heating efficiency and
safety. Elements are available separately for use in OEM equipment.
Special materials and custom designs are available for marine applications, power plants, or
hazardous applications.

. Voltage: Up to 600 V

Process Radiant Air Heaters

Process radiant heaters include a large selection of elements, fixtures, and panels for the best
solution where heated process air or direct contact is impossible, impractical, or undesirable.
Drying, curing, preheating, shrinking, and thermoforming are frequent applications.
Chromalox sensors and controls are available to provide single-source heating systems suited
to your application.

. Watt densities: Up to 5.76 kW/ft2 (61.5 kW/m2)
. Element source temperatures: Up to 4,000°F (2,200C)
. Heating element and panel materials available: INCOLOY*, Quartz, and ceramic

Storage Tank Heaters

Chromalox offers uniquely designed electric heating systems for storage tanks. The systems
can be installed in above- or below-ground tanks made of steel, concrete, or fiberglass.
Several feature a unique replaceable-element design whereby the heating elements can
be removed and replaced without draining the tank. Very little upkeep is required, making
them practically maintenance-free. When combined with temperature controls, power
controls, and safety monitoring they provide complete tank heating systems.
