DHN now available with EC fans

We advance in implementing energy saving EC technology to further models. Latestly we upgraded our double exhaust cooler DHN.

The DHN unit is often used in food preparation rooms. Due to the presence of people inside the cold room not only capacity and efficiency are points to consider during desinging the refrigeration system. Furthermore noise and draught- free air flow are major factors think about. That is why we upgraded our exisiting DHN model with the following functions:
  • Energy saving of up to 80% (DHN 401 S to DHN 401 S EC)
  • Noise reduction between 1 -2 dB(A) due better fan blade design
  • Stepless speed control by 0-10 V signal
  • Motor protection features e.g.: Blockade, Temperature
For easyness of design and selection we kept the allready well- known model names of the unit. The DHN 401 S EC has the same cooling capacity like the old DHN 401 S. To ensure a running model in cases when speed control isn't needed the speed is fixed ex factory with resistances. Simply take out the resistances and connect a 0-10 V signal for a full controlable unit. For more information have a look at our <media 5>bochure</media>.
