Various coils are used in restaurant equipment componentry. An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix. They are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, generators, inductors, electromagnets, transformers, solenoid valves, and sensor coils. Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely an external time-varying magnetic field through the interior of the coil generates an EMF (voltage) in the conductor.

In refrigeration equipment, the "condenser coil" dispels hot air to the outside of the space. The refrigerant then loops back to the compressor, gets cold again, absorbs heat and disperses it to the outside. As long as the compressor is running, the refrigerant keeps up this continuous loop. Extracting heat from the storage space and transferring it to the refrigerant is the function of the "evaporator coil".

In dish washing machines, the steam coil preheats incoming water, reducing the energy needed to heat the water used in the sanitizing rinse.

Contactors are widely used in all kinds of restaurant equipment. A contactor is an electrically-controlled switch used for turning an electrical power circuit on and off. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit itself, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
