COMPRESSOR RELAY 820ARR3H23
Compressors are used in all kinds of restaurant equipment from refrigerators and freezers to walk-ins, from merchandisers and display cabinets to condiment and frozen beverage dispensers and much more. A compressor is a mechanical device (a motor) that increases the pressure of a gas by reducing its volume to affect cooling via the transfer of heat.
Compressors used in refrigeration systems are often described as being either "hermetic" or "semi-hermetic". The difference between the hermetic and semi-hermetic types is their design and construction. A hermetic compressor has a one-piece welded steel casing that cannot be opened for repair -- if the hermetic unit fails, it is simply replaced with an entirely new one. A semi-hermetic compressor uses a large cast metal shell with gasketed covers and screws that can be opened in order to replace the motor and other internal components.
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.
Master-Bilt (sometimes spelled "Masterbilt" or "Master Built") offers a broad line of refrigerated cabinets includes ice cream dipping cabinets, open air merchandisers, refrigerators, and reach-in cases utilized in the foodservice, convenience store and restaurant industries. They also produce walk-in coolers and freezers ranging in size from 30 square feet to complete refrigerated warehouses. In addition, their condensing units and refrigeration units are considered by many to be the best in the industry.
