GSN

Floor mounted air cooler

Features

Advantages

  • Particularly suitable for deep-freeze storage roomsand process engineering
  • Connecting frame for air ducts
  • Fans with external pressure

Installation – Inspection – Maintenance

  • High capacity in one unit
  • Easy access to all components
  • Large maintenance flaps

Good Defrosting Behaviour

  • Standard with defrost flaps
  • No steam discharge
  • The defrosting heat remains in the casing

Good Air Distribution

  • Air distribution with ducts
  • Fans for external pressure

High Operational Reliability and Leak-Safety

  • Proven Güntner floating coil principle (refrigerant)
  • carrying tubes do not make contact with the casing,increases the heat exchanger’s service life)
