Crisp and fresh fruit and vegetables 365 days a year

Crisp and fresh fruit and vegetables 365 days a year

The new site of the fruit and vegetable production organisation OGA OGV Nordbaden eG in the industrial zone of Industriegebiet West in Bruchsal is one of the most modern fruit and vegetable logistics centres in Europe. Güntner air coolers and condensers have been used in the new logistics centre since spring 2015 to ensure that the high quality of the sensitive goods is maintained. In the storage rooms, the slight difference in temperature with the Güntner agri coolers ensures a low level of product dehumidification and fluid coolers with flooded evaporation guarantee optimum energy efficiency.

Deep-freezing at external temperatures of above 50 °C

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.
