    What type of heat exchangers can Danfoss offer?

    We offer a wide range of gasketed (XG) and cupper brazed (XB) heat exchangers. The product portfolio offers you a wide range of standardized and custom designed plate heat exchangers - designed especially for use in district energy applications. Various sizes and models are available from stock.

    In which applications can we use Danfoss heat exchangers?

    1. DISTRICT HEATING & COOLING/MICRO NETWORKS
    In district heating systems, MPHEs are used in the hydraulic interface between the district heating network (primary side) and the heating system within one- and two-family houses (secondary side)

    2. DECENTRALIZED HEATING SYSTEMS
    In multi-family buildings, MPHEs are optimal for use in decentralized systems where each flat has its own hydraulic module, also known as flat stations

    3. SOLAR COMBI SYSTEMS
    MPHEs are perfect for systems where thermal solar heating is the primary energy source backed up by an auxiliary heat source, such as a gas boiler or district heating

    What does it mean that a heat exchanger is a Micro Plate™ Heat Exchanger?

    It's an award winning technology - changing the industry and invented by Danfoss.
     
    Using our new Micro Plate™ technology, Danfoss heat exchangers outperform everything else on the market with an incredible 35% lower pressure loss or 10% better heat transfer. The unique plate design means your district heating application can even be individually recalibrated to match your specifications – so you choose what’s best for your network.

    How does the Micro Plate™ plate design achieve better performance?

    Characterized by their unique plate pattern;
     
    1. UP TO 10% ENHANCED HEAT TRANSFER
    Due to a more uniform flow velocity, fluid is distributed and mixed better and enhance the heat transfer rate by up to 10%

    2. UP TO 35% LOWER PRESSURE LOSS
    Thanks to the unique plate design, the way that water is distributed inside the MPHE also reduces pressure loss. This means less energy is needed to drive the water round the system and consequently also lowers running costs

    3. LONGER LIFE TIME
    MPHEs enjoy a longer lifespan than other kinds of heat exchangers. This is due to larger brazing point, which provides a more robust heat exchanger. Scaling and fouling is furthermore reduced due to improved flow throughout the plate

    How do you assure the quality of Danfoss heat exchangers?

    Quality First. Danfoss products are manufactured to the highest standards. Our facilities have been awarded all necessary certifications, including ISO 9001/14001 and ISO/TS 16949.

    What is the difference between 1-pass and 2-pass heat exchanger?

    1-pass principle:

    • High thermal temperature difference, T11 and T22 connection is on the same side, often an advantage

    2-pass principle

    • Applications where low thermal temperature difference is required (T11-T22)
    • Two step heating systems with after-cooling (pre-heating)
    • Domestic hot water production
    • Domestic hot water production with circulation

    How can we specify a heat exchanger?

    • Loads
    • Temperature conditions (inlet-outlet temperatures for primary & secondary side)
    • Limitations of heat exchangers (max required pressure drops)
    • Connection type and sizes (threaded, o-ring, flange, etc.)
    • Heat exchanger type (gasket or brazed)
    • Accessories (insulation, brackets, tail pieces)
