The Accudraft standalone heat generator is a fully independent heating unit that provides high heat efficiency and installation versatility. The Standalone can be located virtualy anywhere and provides a high rate of heat efficiency when compared to other independednt heaters available on the market. The Accudraft Standalone has a 50/50 fresh air recirculation system that passes incoming air by the fire or heat exchanger twice before sending it into the spray booth. Other units simply rush air by the flame once and dump straight into the spray booth using excessive fuel to acheive proper curing temperatures. For even higher efficiency, add EnergySmart™ VFD's or check out the Accudraft KD™ or Timeless™ integrated heating systems.
