Product description

Handling and operation

  • Particularly powerful compressors and large heat exchangers for desert conditions
  • Quiet normal running due to frequency-controlled fans and sound-optimised compressors
  • Different operating modes due to fully automatic Siemens S7 controller: very quiet (whisper mode - often used during the night), rapid cooling (booster mode ), ventilation operation (only air) and normal operation
  • Efficient, large-area filters with integrated filter monitoring
  • Increased safety through counter pressure display
  • Optimal control through viewing windows in the air cooler
  • Effective device protection through integrated phase and undervoltage monitoring
  • Reliable start-up even at low outside temperatures due to four speed-controlled condenser fans
  • Simple and thorough cleaning due to good accessibility, e.g. by heat exchangers with wide fin spacings, housing doors, manholes and inspection openings in the air duct

Energy and environmental balance

  • Economical solution due to low power consumption
  • Energy-efficient design due to frequency controls and the latest motors
  • Environment friendly safety refrigerant - without CFCs and without HCFCs
  • Additional energy savings through winter and summer thermostats
  • Permanent compliance and monitoring of desired cooling air humidity and temperature with HYGROTHERM™
  • Integrated sound insulation

Workmanship and quality

  • HYGROTHERM™ heating coil as standard
  • Robust construction due to stainless steel condensate tray
  • Corrosion protection through coated heat exchangers
  • Extra safe chassis equipment with puncture-proof solid rubber tyres, optionally swivel castors
  • Multi-stage quality control with factory test run
  • Easy maintenance Large, fully panelled doors
  • Robust industrial design
