Main air heater for heating the gas stream electric heating equipment. Air heater heating elements of stainless steel electric heating tube, a plurality of heater cavity baffle (baffle plate), to guide the gas flow direction, the cavity extending the retention time of the gas, so that the gas is sufficiently heated, the gas uniform heating, improve the heat exchange efficiency. The air heater heating element Stainless steel heating tubes, seamless steel pipe was charged in the electric wire, a space portion filled with a good thermal resistance and insulating properties of magnesium oxide powder formed after the shrink tube. When the current through the wire when the temperature resistance, the heat generated by crystal magnesium oxide powder to the heating tube surface diffusion, and then transmitted to the air to be heated in order to achieve the purpose of heating. Shanghai Electric] [Chuang sea market in electric heaters have many years of manufacturing experience, we have designed and manufactured for the customer when the air heater, heating according to the customer's actual needs, tailored to the customer. Such as to confirm the nature of heated gas, heating the gas, the initial temperatures T1, the final temperature T2, the voltage heaters, heating up time, the gas flow per unit of time, so as to design the best solution customers. Professionally designed heaters, customized heater effect, the use of safer, [Chuang sea Electric] worthy of your trust!
