Product description

Handling and operation

  • Particularly powerful compressors and large heat exchangers for tropical conditions
  • Quiet normal running due to frequency-controlled fans and sound-optimised compressors
  • Different operating modes due to fully automated Siemens S7 controller: very quiet (whisper mode -often has to run at night), rapid cooling (booster mode), ventilation mode (only air) and normal operation
  • Efficient, large-area filters with integrated filter monitoring
  • Increased safety through counter pressure display
  • Optimal control through inspection windows in the air cooler
  • Reliable start even at low outside temperatures due to speed-controlled condenser fans
  • Easy and thorough cleaning due to good accessibility e.g. by heat exchangers with wide fin spacing, 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 state-of-the-art motors
  • Environment friendly safety refrigerant - without CFCs and without HCFCs
  • Additional energy savings through winter and summer thermostats
  • Permanent compliance and monitoring of setpoint cooling air humidity and temperature with HYGROTHERM™
  • Standard sound insulation for GC 220-GC 560

Workmanship and quality

  • HYGROTHERM™ heating coil as standard
  • Robust construction due to stainless steel condensate tray
  • Corrosion protection through coated heat exchangers
  • Chassis with robust pneumatic tyres for increased puncture protection for GC 60, optional swivel castors
  • Extra safe chassis equipment with puncture-proof solid rubber tyres with GC 220 - GC 560, optionally swivel castors
  • Multi-stage quality control with factory test run
  • Easy maintenance due to large, fully panelled doors
  • Robust industrial design
  • Depending on the design, large TÜV-tested refrigerant collectors and subcoolers
  • CE-compliant versions

Options

  • High pressure blower (HP) for slim-line silo cells
  • Protective grille against animals
  • Parking supports
  • Forklift pockets for easy device transport using a forklift
  • Alarm modem (notification via SMS/email) for permanent monitoring
  • Modem for remote diagnosis/remote display (app, LAN, WiFi / WLAN, GSM)
  • Sound-proof cabin for -15 to -20 dB(A)
  • Electrical heating coil
  • Rotating field monitoring for effective device protection
  • Signal light for convenient device monitoring from a distance
  • Fully automatic cool stop function
