Ceiling Hung Unit Cooler


Güntner incline design

  • Enhanced condensate flow
  • Improved drain pan

Effortless cleaning

  • Hinged fan assemblies provide easy access to the coil for cleaning purposes
  • Construction detail takes accessibility into account and does not allow for tight spots
  • All parts are easily accessible for service and cleaning purposes

Installation / Maintenance / Inspection

  • Refrigerant connections are easily accessible within the hinged panels
  • Reduced installation costs
  • Factory fitted accessories (optional) reduce installation costs
  • Hot gas piping between coil and pan, complete with check valve, factory fitted

Fans & motors

  • Reliable high quality fan and motor combination
  • Increased air throw with Güntner streamer (optional)
  • High air quantities
  • Premium efficient motors
  • External rotor design or "standard" squirrel cage design

Refrigerant distributor

  • One TXV per unit for most evaporators
  • Refrigerant distribution into coil is optimized via specific selection based on operating conditions and refrigerant

Proven Güntner floating coil concept

  • The proven Güntner floating coil concept prevents the refrigerant carrying tubes from coming into contact with the tube sheets. This concept allows for thermal expansion and contraction of the tubes without the risk of tube damage at the tube sheets, thereby reducing the chances of refrigerant leaks
