      Hot Water Supply System Steam Fired Instantaneous Water Heater | One-Way Method LM15-Ⅳ

      Features/Applications

      Features

      • Can be installed in tight spaces thanks to its compact design (small/lightweight).

        With a compact size, this product can be wall mounted in the place it is required.

      • Provides clean hot water

        Employs an indirect heating system* with water and steam.
        *Indirect heating system refers to a system of heating that uses a heat exchanger and where the water and steam do not come into direct contact.
        This means that the quality of the hot water is not impacted by chemicals or other matter in the steam.

      • Industry top-class hot water supply volume

        Compact, yet able to instantaneously supply up to 30ℓ/min of hot water.

      • High thermal efficiency

        Thermal efficiency of 91% that surpasses gas and electric hot water supplies.

      • Environmentally friendly

        With no combustion taking place within the hot water supply itself, it does not produce chemical substances such as CO, CO2, and NOx, nor does it produce soot.

      • Quiet

        Quiet operation with a background noise of around 45dB.

      • Easy maintenance

        Main consumable components are grouped into a unit.

      • Suitable for use in foodstuff manufacturing

        The design of this product passes leaching tests, meaning the water it supplies can be used in foodstuff manufacturing as is.

      Typical applications

      Can be used in the cleaning of kitchen and kichen equipments, and as water preparing for food processing.

      ●The maximum rated heat output through steam pressure is 46,200kcal/h.
      *Do not exceed 0,4 MPa (58psig) of water supply pressure under static pressure.

      ●If recovering condensate, ensure a pressure differential of at least 0,03MPa (4.4psig).
      If back pressure is applied to the condensate discharge pipe, the maximum hot water supply rate drops.

      ●Low-temperature options: A 30℃ - 50℃ (86°F - 122°F)type*1 can be manufactured. Please do not hesitate to make inquiries.
