electric air heater

Quick Details:

electric air heater
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.
