RH-R heaters are used in mechanical ventilation systems where it is necessary to periodically raise the temperature or maintain the temperature at a constant level in the rooms. They can also be used in technological processes that require the supply of constant temperature air.
Electric duct heaters with integrated regulator, suitable for installation directly in rectangular ducts. The housing is made of galvanized sheet steel and stainless steel heating elements. The heaters are fitted with a double overheat protection system as standard: the first automatic element (temp. +75oC), the second one with manual reset (temp. + 85oC).
Channel heaters should be selected so that the outlet air temperature does not exceed +45oC. The airflow rate of the heaters must not be less than 1,5 m/s.
