Dedicated heat exchangers for high performing heat pumps

Contact us

Heat exchangers are key components in heat pump systems, influencing system's performance, stability, refrigerant charge, overall size and longevity. In times of transition from fossil fuels towards more sustainable measures, this calls for smart and efficient solutions for heating and cooling commercial buildings and homes. 

SWEP heat exchangers can fulfill several vital functions for heat pumps including:

  • High performing condensers with decreased refrigerant charge, footprint, and pressure drop
    thanks to innovative asymmetric design.
  • Evaporators for variable- and fixed-speed compressors with excellent performance during
    reversible mode with distribution device and smaller footprint
  • Double wall technology ensuring high efficiency and safety avoiding leakage where liquids must not mix, without compromising compactness and thermal efficiency of the heat exchanger.

Efficient all-year round heating

Ground stored energy as evaporator heat source

Space heating with efficient performance


Air to water heat pumps

In air to water heat pumps, heat is taken from outside air and used as a heat source in a water-based system to evaporate the refrigerant. The created heat can then be used for comfort heating or to heat tap water. Air to water heat pumps are gaining grounds as efficient all-year round heating systems with low energy cost, reduced carbon footprint and low maintenance requirements.

Ground source heat pumps

The ground source heat pump (GSHP) uses the energy stored in the bedrock, surface soil, or water as the heat source for the evaporator. Our BPHE evaporators have optimized distribution devices to ensure the best possible efficiency in GSHP evaporator duties.

SWEP has a wide range of BPHEs with a long thermal length, which helps to maximize the efficiency of the condensing operation. We also offer double-wall technology heat exchangers providing extra safety, for example when the refrigerant circuit heats tap water directly. Double wall technology gives that extra safety of avoiding leakage where liquids must not mix yet maintains the compactness and thermal efficiency of the heat exchanger.

Domestic hot water heat pumps

In the past, domestic hot water was only a small part of a buildings’ total energy demand. As insulation quality of buildings increases, space heating demand drops. At the same time, hot water usage increases. The ratio between energy requirements for space heating and domestic hot water consumption calls for new solutions with unrivalled performance and efficiency.

SWEPs highly efficient BPHE condensers can be equipped with a distribution system to improve performance and reduce the risk of freezing when they are operating as evaporators.
