Insulated High-voltage Air Heater (400-600V) | PTC Air Heater
Insulated High-voltage Air Heater (400-600V) | PTC Air Heater
HRP High-voltage are electrically insulated PTC finned resistor heaters with high resistance to moisture and dirt for homogeneous heating of air flows
Power up to 2,5kW
Multiple voltage capability at 400 - 600V
High safety and energy efficiency thanks to the PTC effect
Insulated High-voltage PTC Air Heater (HRP HV) up to 600V
To meet the requirement for ever-increasing performance demands, electrified systems are increasingly aiming for voltages of up to 900 volts. The numerous benefits of the voltage increase are driving technical development not only in automotive electrification, but also the entire transportation industry.
Insulated high-voltage PTC Air Heaters of the HRP HV series are powerful heaters for homogeneous heating of air flows. They consist of slim aluminum profiles with press-fitted heating elements, and heating fins in either V- or delta-shape. Cover rails at both ends are equipped with a T-slot for easy installation and for attaching accessories. Thanks to their encapsulated PTC heating elements, the HRP HV series features a higher resistance to moisture and dirt.
HRP HV are available in different versions with power outputs up to nearly 2,5kW. They come in two standard sizes (M, L) with either V- or delta-shaped fins. HRPs HV with delta fins achieve a considerably lower pressure drop with a minimally reduced power output and are particularly suitable for high-volume air flows or lower-performance fans. Insulated high-voltage air heaters are multi-voltage capable and can be operated in a voltage range from 400V to 600V. Optionally, they can be equipped with a plastic frame featuring integrated screw-on points for thermal insulation and easy installation.
PTC Air Heaters come with all advantages of the PTC heating technology. Thanks to the PTC effect, the heating elements dynamically adjust their power without exceeding a maximum temperature. High operational reliability and energy efficiency without any additional switching elements.
