A centralized deicing system includes, in one embodiment, a large fixed location supply tank of deicing fluid which is heated and supplied to a plurality of terminal boxes located at several aircraft loading ramps. The system includes a recirculation loop for preheating the conduits for the deicing fluid by circulating heated deicer fluid through them before application to an aircraft. Each terminal box includes a coupler for receiving ends of a hose employed on a movable vehicle used for deicing an aircraft to also preheat the hose. In one embodiment of the invention, separate tanks of water and glycol are provided, and the terminal box includes a mixing valve which can be remotely controlled by an operator for blending the heated water and glycol in the desired proportion depending on weather conditions.
