• Excellent durability ensured by unique internal structire (hemispherical valve| etc)
  • The upper plug is made of stainless steel ensuring excellent wear resistance
  • Reilaible performance due to all stainless steel internal parts
  • Super energy saving since intermittent operation removes air adiabatic wall in the heat excahnger & increases heat efficiency considerably
  • Made by Yoshitake Japan
