Sea Water Source Heat Pump (IWS-55A, 53A, 13A series)

Sea Water Source Heat Pump (IWS-55A, 53A, 13A series)
  • * Product Overview
  • An eco-friendly heat pump system that recovers sensible heat from the sea
    water and supply the recovered heat to the heat/cool the water tank, or produce
    cold/hot water without using any fossil fuel thereby saving energy and reducing
    greenhouse gas
  • * Features
  • ① Significantly saving energy costs associated with heating and cooling of
         the water tank at eel farms and aquaculture farms
    ② Maintaining the optimum temperature by accurate temperature control for the
        growth of the young and live fishes
    ③ Extended equipment life and easy maintenance with the titanium dual pipe
        and spiral tube heat exchanger
    ④ Fitted with the aerification system to the heat source tank so as to generate
        air bubbles to remove sludge and optimize the heat transfer of the evaporator
    ⑤ Ability to recover heat even from the low temperature heat source (up to 5°C)
  • * Application
  • Applicable to any sector that uses sea water as a heat source and requires hot
    water and heating/air-conditioning such as Land aquaculture, Mariculture,
    Offices near the sea shore, Commercial buildings, Motel, Sauna and so on
