WRK finned tube heat exchangers are suitable for efficient direct condensation and evaporation in heat pump buffer tanks. The inner grooved surface of the used finned tubes optimize the heat transfer. Thus highest COP-values are possible even with smallest temperature differences.


Your advantages at a glance

  • Efficient: Highest COP values due to direct integration of the heat exchanger in the storage tank
  • Filling volume optimized: Smallest refrigerant volumes due to compact design
  • Easy handling: Easy replacement and maintenance

Compact sizes, standard sizes – Up to 4000 kW!

Dry Expansion Evaporator

Our dry expansion evaporators guarantee the best performance

  • Internally finned tubes are optimized for flow boiling: high exchange coefficients are obtained with relatively low pressure drops.
  • The refrigerant distribution system allows the tube bundle to be fed uniformly.
  • Solid and customized construction based on project conditions.
  • Possibility of construction with Cu-DHP copper bundle, CuNi90 / 10 cupronickel, 316L stainless steel.
  • Wide range of sizes: diameters from ø194 mm to ø660 mm, lengths from about 1500 to 4085 mm.
  • Available optionals: elastomeric foam insulation, electric heaters, pressure gauges, water filters.


Single-pass counter-current evaporators

In these evaporators, the counter-current configuration optimizes the temperature profile between the two fluids, in order to obtain the maximum local heat exchange coefficient and facilitate the achievement of the desired superheat on suction.

Countercurrent evaporator
  • Powers from 50 kW up to 2500 kW
  • Temperature approach up to 2K
  • Up to four refrigerant circuits

U-Tube bundle evaporators

In these evaporators the refrigerant flows in a bundle of U-shaped tubes; the refrigerant connections are therefore on a single head. Optimized for R410A, R32, R452B, R454B or for low temperature operation, the EV.U guarantees optimal mass flows, such as to guarantee oil return even with scroll compressors.

U-Bundle evaporator
  • Powers from 50 kW up to 2200 kW
  • Temperature approach up to 2-2.5K
  • Up to four refrigerant circuits
  • Higher mass flows (minimum partialization for lower circuit)
  • Design pressure up to 50 bar

Heat Pumps

Dry expansion evaporators can also be used in condensing mode, for heat pump and/or refrigerant cycle inversion systems. The good efficiencies and the versatility of configuration make them excellent alternatives where you want to standardize the layout of the exchangers in low and high pressure circuits. Available with design pressures up to 50 bar and temperatures up to 150° C, Wieland Provides heat pumps are in step with the market needs for low GWP refrigerants or natural refrigerants, such as the increasingly used propane.
