Wattco's duct heaters come in various sizes and dimensions to fit any compartment. There are three types of duct heaters available: open coil, tubular element or finned tubular heating elements that are either flanged or inserted in the duct. Air duct heaters are primarily used in air flowing ventilation systems and comfort heating applications while process duct heaters are mainly used for industrial process heating applications (ovens that require re-circulated air or forced circulation).
Wattco designs and configures your electric duct heaters according to your specifications. Our team is dedicated to research and development of the latest technologies, while striving to meet every customer’s needs by manufacturing high quality duct heaters. Since 1969, WATTCO has expertise in developing and manufacturing electric duct heaters that make Wattco duct heaters, the most easily adaptable solutions for most non-pressurized, air-heating systems.
A broad range of custom built electric duct heaters with capacities up to 1000kW is available upon request. WATTCO™ heaters can be used for applications with the following voltages:
