AC air heater unit HRKK series

HRKK with Delta-Shaped Fins | PTC Air Heater PTC Air Heater HRKK with patented delta-shaped fins for homogeneous heating of air flows at low pressure drop Power up to 2kW Voltage 230V High safety and energy efficiency thanks to the PTC effect PTC Air Heater with Delta-Shaped Fins (HRKK Delta) PTC Air Heaters of the HRKK Delta series are powerful heaters for homogeneous heating of air flows. They alternately consist of PTC heating elements and delta-shaped heating fins. The delta-shaped fins were specially designed for large air flows and have a significantly lower pressure drop compared to the classic V-shaped fins. HRKK Delta are particularly suitable as pre- or post-heaters in air conditioning & ventilation systems, or as cabin heaters in special-purpose vehicles. PTC Air Heaters HRKK Delta are available in three standard sizes S, M, L with power up to 2kW. They feature a plastic frame with integrated screw-on points and are suitable for a voltage of 230V. 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. FEATURES Power up to 2kW per heater Can be operated at 230V AC or DC Available in standard sizes S, M, L with delta-shaped fins Plastic frame with integrated screw-on points for easy installation Optional: Mounting frame, temperature limiter Customer solutions (size, voltage, power) on request
