WQ1480.C 8/04 V W4EIUnAF(EC)S, 4 units: each with 4 fans diameter 800mm low noise (around 27dB(A)10m on working point) and low absorptions (around 380W on working point)

GQ1780. C 8/04 V W4EIUnAF(EC)S, 2 units: each with 7 fans diameter 800mm low noise (around 28dB(A)10m on working point) and low absorptions (around 651W on working point)


Heating of different buildings

Client's Needs

The installation site, located in Switzerland, requires an innovative solution with several units for the heating of different buildings, each with a capacity of 21/30kW. The dimensioning of the units had to take into account both the need of a low noise solution for residential installation and the low temperatures of Central Europe, thus foreseeing the possibility of heating fluids from -14 to -11°C in case of low temperature. The customer underlined the need to reduce CO2 emissions and gas cost.

ThermoKey Solution

ThermoKey sourcing its experience of similar installations provided a tailor-made solution based on heat pump systems installed outdoors combined with heat pump/compressors located indoors. The customized drycoolers use the energy from the air to produce hot water for district heating. The units are equipped with EC fans granting low noise levels, specific exchangers with large fin spacing and rendundant deair and ventile, and customized casing with special feet allowing inclination of the cooler on the left or right side.

Added value

  • Dedicated feet allowing water to drop on the side of the
    cooler in case of water forming during defrosting.
  • Special design allowing to incline the unit on both sides
    while keeping the electrical equipment (electrical box and
    EC controller) in position.
  • Fin spacing as high as possible and large fin thickness
    make maintenance, cleaning, and inspections easier during
    winter time.
