Floor mounted air cooler
Features
Air coolers are finned heat exchangers in which a working fluid heats up with heat absorption from the environment to be cooled, without changing the aggregate state. The units serve as components of a system, e.g. for conditioning the room air or cooling goods.
Evaporators are finned heat exchangers serving as components of a refrigeration system, in which liquid refrigerant evaporates with heat absorption from the environment to be cooled. The units are used e.g. in deep-freeze applications in food storage.
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)

Hop cooling by Güntner
The hop wholesaler Simon H. Steiner "Hopsteiner" halved the operating costs for his new propane refrigerating plant, compared to the existing plant. Thanks to this efficient technology, the refrigerating plant designed by Schiessl made it to the jury short list in the "Commercial Refrigeration" category of the Chillventa Award 2016.
