Cooling equipment relays such as AC relays, potential relays and refrigerator compressor relays provide switching when one signal is required to control multiple circuits, or when a circuit needs to be controlled by a separate, low-power signal. You're likely to find cooling equipment relays in HVAC systems and maintenance setups that include air conditioning or refrigeration. In addition to switching, these relays help to efficiently cool environments as well as maintain air quality and temperature. You can also browse refrigeration controls for defrosting, compression, water cooling and more. HVACR relays, also available, are designed specifically for use in HVACR (heating, ventilation, air conditioning and refrigeration) systems.
