Design/Options

electric design

  • control system with TCS for the regulation of all unit functions
  • connection to higher level control
  • regulation of summer/winter mode with draining
  • continuous regulation of the fan speed
  • regulation of the deluging water circuit with desludging and refilling function
 

heat exchanger coil

  • high protection against corrosion thanks to cathodic dippaint coating
  • protective grid for the filtration of pollen and dust
 

water circuit

  • deluging of the finned surface for an increased performance and a decreased medium temperature
  • UV lamps to prevent microbial growth
  • long cleaning intervals due to optimized tray design
