Duct type heater 风道式加热器

Duct type heater is mainly used for the air duct heating, specifications into low temperature, high temperature, and three forms, on the structure in common is USES the steel plate support electric heating tube to reduce the vibration, electric heat pipe junctions are equipped with overtemperature control device. Another in control except with overtemperature protection outside, still in the air blower and adding intermodal transportation device, between heater to ensure electric heater starting in fan starting later, must be in heater before and after adding a differential pressure device, in case the fan fault, the channel heater heating of gas pressure generally should not be more than 0.3 Kg/cm2, if need to surpass the above pressure, please choose circulating electric heater, Low temperature type heater gas heating the highest temperature ℃; no more than 160 In not more than 260 temperature type ℃; High-temperature type less than 500 ℃.

风道式加热器主要用于风道中的空气加热,规格分为低温、中温、高温三种形式,在结构上的共同之处是采用钢板支撑电热管以减少电热管的振动,接线盒中都装有超温控制装置。另在控制方面除装有超温保护外,还在风机与加热器之间加装联运装置,以确保电加热器起动必须在风机起动之后,在加热器前后加一差压装置,以防风机故障,通道加热器加热的气体压力一般不应超过0.3Kg/cm2,如需超过以上压力,请选用循环式电加热器;低温型加热器气体加热最高温度不超过160℃;中温型不超过260℃;高温型不超过500℃。
