The rugged, efficient, open Frame Duct Heaters offer you the capability to heat large volumes of air with fast warm-ups and cool-downs. Our open design provides low pressure drops with no build up of excessive temperatures and the low static pressures allow you to use smaller, more economical blowers.
Coils are exposed directly to the air flow enabling immediate heat transfer from wire to air while remaining relatively cool themselves. A range of sizes are available to meet your specific needs - including voltages up to 600 volts - single and three phase. The Frame Duct Heaters have a long history of trouble free service and are easy to install. This heater is intended for use in any application including residential, commercial, and industrial processes
Open coil heating elements from HSCO are typically made for duct process heating, forced air & ovens and for pipe heating applications. Open coil heater elements are made to fit inside standard 2’’ or 3’’ schedule 40 NPS pipe. Open coil heaters are used in tank and pipe heating and/or metal tubing. A minimum clearance of 1/8’’ is required between the ceramic and the inside wall of the tube. Installing an open coil element will provide excellent and uniform heat distribution over a large surface area.
Open coil heater elements are an indirect industrial heating solution to decrease watt density requirements or the heat fluxes on the surface area of the pipe connected to the heated section and prevent heat sensitive materials from coking or breaking down.
