Güntner Air cooler Insulated Logistics
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
- All components are installed in an insulated casing at the factory
- Set-up either inside or outside the storage facility
- Optimal defrost results due to closable defrost flap
- Design for storage with and without air ducts
Easy to Install
- Refrigerating unit completely factory-fitted
- Reduces installation costs
Inspection and Maintenance
- Can be accessed or heated for service work
- Easy access when installed outside the storage facility
- Logistics operations are not hindered during inspection and maintenance work

Deep-freezing at external temperatures of above 50 °C
More than 5 million inhabitants live in the ever-growing Saudi Arabian megacity of Riyadh. The city is surrounded by the desert, the climate is sub-tropical. The technical requirements placed on a cold store for food are accordingly stringent. Güntner supplied 23 THERMOSTORE insulated unit coolers, 22 GGHN air coolers as well as two AGVH 090 ammonia condensers for the new cold storage of the Shahini Group. Two thermowave TL 250 plate heat exchangers form the hydraulic interface between refrigerant and fluid.
