Applications
    • Direct Heating
      Direct Heating

      The direct hot water supply system integrates renewable and energy-efficient equipment, including solar collector panels, heat pumps, and high-efficiency plate heat exchanger compact units. The primary circuit maintains a hot water temperature of 70°C. Solar collector panels provide the initial heat source, while heat pumps and electric hot water calorifiers provide additional heating and backup support when required. The secondary circuit receives cold water at 15°C and passes through the IES compact unit, where it is heated to 60–65°C for central hot water supply.

    • Indirect Heating
      Indirect Heating

      The indirect hot water supply system uses a two-stage heating process. In the first stage, cold water enters the IES preheat heat transfer compact unit and is heated from 15°C to 43°C through an air-conditioning heat recovery chiller. The preheated water then enters the IES booster heat transfer compact unit, where a high-efficiency condensing hot water boiler raises the temperature to 60–65°C. The heated water is stored in the hot water storage tank before distribution through the central hot water system.

    • Swimming Pool Heating
      Swimming Pool Heating

      The packaged heat exchangers are suitable for swimming pool heating and cooling systems. The integrated heat exchange system continuously monitors and regulates pool water temperature to maintain comfortable conditions throughout the year for both indoor and outdoor pools.

    • Space Heating
      Space Heating

      Commercial buildings, hospitals, and hotels often require heating systems to maintain comfortable indoor temperatures. Our compact plate heat exchanger can be configured for space heating applications with heat sources such as boilers, heat pumps, and heat recovery chillers. The built-in plate heat exchanger transfers heat between separate fluid circuits through indirect heating, creating an efficient connection between the heat source and the heating system

    • District Cooling

      The district cooling compact units are suitable for office buildings, factories, hospitals, and high-rise buildings. The integrated system uses high-efficiency plate heat exchangers with modulating control functions to match cooling demand and optimize system operation.
