The electrically powered air heaters of the LE-P series are mainly used where large quantities of gaseous media have to be heated. LE-P air heaters can be found, for example, in drying systems, hot-air shrink systems, heating cabinets, hot-air ducts and preheating systems. The heating elements and housings are made of high-quality stainless steel, which is why they heat dry, moist and mildly aggressive air as well as nitrogen in fresh air or recirculating air operation. The equipment is easy to control and, with its compact dimensions, can be installed with only a small footprint.Since the return of hot air is possible with HAPRO air heaters, they are very energy efficient. All versions are designed for continuous operation.
The air heaters are fully thermally insulated (with the exception of the inlet and outlet nozzles). The devices are available with an output of 24 – 72kW, and special designs are possible. Customized layout pressure-resistant up to 5 bar (LE-D). Inlet temperature in recirculating operation is max. 300°C, continuous outlet temperature is 350°C.
