W-COVER HEATER BOOSTER DOOR

A booster pump is a device that increases the pressure of a fluid. They may be used with liquids or gases, and the construction will vary depending on the fluid. A gas booster is similar to a gas compressor, but generally a simpler mechanism which often has only a single stage of compression, and is used to increase pressure of a gas already above ambient pressure.

Doors are common in restaurant equipment design from refrigerators and freezers, to ovens to ice machines. A door is a hinged or otherwise movable panel that allows access to an enclosure, cabinet, bin, or other cavity or container.  A door assembly comprises the components that work in tandem to allow the door to function properly such as the door set, strike, catch and lock set. Doors may be hinged and swing open and closed, or they may slide within a frame. Very frequently, restaurant equipment doors feature tempered glass windows which allow for visual inspection or merchandising of food and beverage products.

A heating element converts electrical energy into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element. This process is independent of the direction of current.
