The LHS 21L PREMIUM air heater features an integrated, active device and heating element cover. An additional implemented alarm contact ensures high process safety warns of excess temperatures and the resulting failures. The heating power can be continuously adjusted via a rotary potentiometer. The air heater is perfectly suited for continuous operation and delivers continuously high output in industrial production processes with its associated external blower.
