Heating, ventilation, and air conditioning (HVAC) units operate in a variety of process and manufacturing facilities across the globe. HVAC systems should be able to withstand harsh environments such as rain, winds, and debris. Therefore, the ideal power switching and motor starting solution for HVAC applications will be rugged and robust, yet compact and versatile.
Vacuum contactors help control the motor for HVAC units in industrial applications. As you can see in the illustration, the Joslyn Clark CV Series vacuum contactor is housed in the control panel of a utility room to help tell the HVAC motors when to switch on and off.
