HVAC

Automotive Heating, Ventilation, and Air Conditioning (HVAC) systems have evolved from simple mechanical controls to advanced electronic architectures that deliver superior comfort, energy efficiency, and performance. Today’s climate systems rely on intelligent electronics to manage airflow, heating and cooling while meeting the demands of electrified and software-defined vehicles.

Modern HVAC applications include HVAC Controls for precise temperature and airflow regulation, PTC Heaters for rapid cabin heating and E-Compressors for efficient electric air conditioning. Additionally, EV pumps and fans ensure optimal thermal management for batteries and power electronics, while traditional automotive pumps and fans maintain cooling for internal combustion and hybrid systems.
