Vacuum Contactor Applications for HVAC

Dependable Power Switching and Motor Starting Solutions for HVAC

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. Typically, HVAC systems operate in areas with little protection from elements 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.

Refrigeration, cooling, and ventilation equipment need an AC motor system to operate. Reliable power switching and motor starting is critical to delivering dependable HVAC at all times. Lags in the power supply or system start-up of an HVAC unit can affect the lifespan, leading to costly and time-consuming downtime. Process and manufacturing facilities rely on Joslyn Clark, where heavy-duty cycling of HVAC system motors require vacuum contactors to provide robust motor control and power supply.
