DEFROST RELAY
SKU: CDZ08218181
Condition: NEW
The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer: For every 6, 8, 10, 12 or 24 hours of compressor operation it turns on a defrost heater for 15 minutes to half an hour.
A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more, thereby preventing excessive heating of the freezer compartment. The defrost timer is such that either the compressor or the defrost heater is on, but not both at the same time.
Relays are electrical devices that are used to control circuits in restaurant equipment and other types of machinery. They work by using a small electrical current to control a larger current, allowing a low-power control circuit to switch a high-power circuit on or off.
In restaurant equipment, relays can be used to control a variety of functions, such as turning on and off motors, controlling heating elements, and activating alarms. For example, a relay might be used to turn on a refrigerator's compressor when the temperature inside the fridge reaches a certain level, or to turn off a stove's heating element when the temperature reaches a certain point. Relays are often used in restaurant equipment because they can handle large amounts of current and are able to switch circuits on and off quickly and reliably.
