HRKK Delta M 24/24 PTC Air Heater – 230 V

Product information "HRKK Delta M 24/24 PTC Air Heater – 230 V"

HRKK Delta M 24/24 PTC Air Heater – 230 V

The HRKK Delta M 24/24 230 V is a powerful PTC air heater with patented delta-shaped fins, engineered for homogeneous heating of airflows in ventilation and HVAC systems, industrial automation, and special vehicle cabins. Operating at 230 V (AC or DC), this medium-sized model is ideal for efficiently heating large volumes of air with minimal pressure drop.

Key Features

  • High Heating Power: Delivers 1375 W at 20°C and 300 m³/h airflow, making it suitable for medium to large air heating applications.

  • Delta-Shaped Fins: Patented fin design ensures uniform heat distribution and significantly reduces pressure drop compared to classic V-shaped fins.

  • PTC Technology: Self-regulating ceramic heating elements dynamically adjust output, preventing overheating and maximizing safety and energy efficiency.

  • Flexible Operation: Operates at 230 V AC or DC; supports independent switching or cycling of four separate heating circuits for precise control.

  • Robust & Compact: Durable plastic frame with integrated screw-on points for easy installation; thermal insulation of the heating elements through the frame.

  • Low Maintenance: Maintenance-free operation thanks to the PTC effect—no additional switching elements required.

  • Safety: Flammability rating UL94V-0; optional temperature limiter and mounting frame available.
