HVAC

Solutions

Today’s automotive climate systems are no longer mechanically controlled. The need for improved energy efficiency, comfort, and performance has pushed Heating, Ventilation, and Air Control (HVAC) systems to adopt more sophisticated technologies and electronics components. Multiple inputs from a variety of sensors and passenger desires require the control of different types of motors, such as stepper motors for flaps, and DC/BLDC blower fan motors. We offer a wide variety of products with the exact specifications and functions required to make HVAC control modules an integrated part of the cabin environment.
