Adiabatic dry coolers



thermofin®-dry coolers can be equipped as an option with AdiabaticPads. This type of adiabatic pre-cooling allows return and condensation temperatures below the ambient temperature or a considerably higher unit performance with the same space requirements and an improved system efficiency.

thermofin® adiabatic management (TAM):
The thermofin® adiabatic management enables a water-saving operation by individually adapting the wetting water quantity via a regulation valve. The required water quantity is calculated and regulated with the TCS (thermofin® control system) by measuring of the ambient temperature, the relative air humidity and the fan speed. The pressure-less operated water distribution system ensures a uniform wetting of the pads also with low water quantities. The excess water is drained through the tray construction which are installed below the stably framed AdiabaticPads and can be connected to the sewage system. As option, also the draining of the fresh water supply line can be controlled via the TCS.



intelligent control via TCS

  • regulation of the deluging water quantity depending from the ambient temperatures
  • continuous speed regulation of the fans and control of day and night mode
  • freeze protection & hygiene: draining of the deluging water circuit
  • demand-based water quantity control through innovative TAM

corrosion protection & service

  • corrosion protection of the heat exchanger, because the humidification is limited to the pad system
  • low requirements on water quality, mostly no water treatment required
  • easy replacement of the pads due to cartridge design
  • direct access to the water distribution


  • self-draining tray and distribution system
  • no circulating water and no stagnation
  • no aerosol output and vapour-free
