Leister 230V 3300W LHS 21L PREMIUM Air Heater - 140.457
Details Reliable and safe
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.
The LHS 21L PREMIUM is designed for special assembly in machine systems. Thanks to its quick and easy to change heating element, maintenance downtimes are kept to a minimum, thereby keeping profits up. The innovative hot air technology also provides outstanding results for very specific industrial applications: Continuously heating furnaces and containers, activating and dissolving solvent-free adhesives and hot melt adhesives, as well as removing plastic flash and polishing plastic surfaces.
