Industrial Hot Water Boiler Wooden Box Packing With Internal Control System
Product description
Duct heaters are mainly used for heating air through the duct. There are three types, low temperature, middle temperature and high temperature. The outer stainless steel sheath and construction can reduce the vibrationof heating elements. There is a overheat protector in the terminal box. Air pressure through the duct should not exceed 0.3KG/cm². Or else it is better use recirculation duct heaters.
Max temperature of low temperature duct heater is not more than 160 C. Max temperature of middle temperature duct heater is not more than 260 C.
Max temperature of high temperature duct heater is not more than 850 C.
