Electric duct heater designed for installation directly in round ventilation ducts. It is used in mechanical ventilation systems, where there is a need to increase the temperature in winter, maintain a constant temperature in the rooms, as well as in technological processes that require the supply of air at a constant temperature.

Construction

• stainless steel heating elements
• installation directly in round ventilation ducts with standard diameters (100-400 mm)
• double overheating protection system: automatic (temperature +75 C); with manual release (temperature +85 C)

dimensions

The duct heaters should be selected so that the outlet air temperature did not exceed + 40 ° C. The air velocity through the heaters should not be less than 1.5 m / s.
