Built for the thermal curing requirements of localized aerospace coating repairs, this unit delivers localized heating via hot-air circulation: the host heats air to the setpoint temperature and routes it through multiple insulated hoses into a flexible thermal blanket placed over the workpiece, forming uniform circulating hot air so the repaired coating cures evenly without moving large skins or fuselage sections into an oven. Multiple hot-air channels supply the blanket simultaneously under closed-loop temperature regulation to accommodate diverse coating formulations. With a mobile architecture, the host, control cabinet, and thermal blanket transfer effortlessly between workstations for on-site localized repair of curved aircraft skins and structural bays.
