A bracket is a device that connects to a structure (such as a panel or frame) and is usually designed to support a vertical load or to strengthen an angle or to maintain a component in its proper position. An evaporator is a device used in a process to turn the liquid form of a chemical substance, such as water, into its gaseous form (vapor). The liquid is evaporated, or vaporized, into a gas form of the targeted substance in that process. One kind of evaporator is a kind of radiator coil used in a closed compressor driven circulation of a liquid coolant. That is called an air-conditioning system (A/C) or refrigeration system allowing a compressed cooling chemical, such as R-22 (coolant) or R-410A, to evaporate/vaporize from liquid to gas within the system while absorbing heat from the enclosed cooled area (for example, a refrigerator or indoor room) in the process. This works in the closed A/C or refrigeration system with a condenser radiator coil that exchanges the heat from the coolant into the ambient environment. Fans are used across a wide variety of restaurant equipment to create airflow and dissipate heat. A fan consists of a rotating arrangement of vanes or blades which act upon the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing or case. This may direct the airflow or increase safety by preventing objects from contacting the fan blades.
