Recipharm Wasserburg

In a project commissioned by Recipharm, a cryogenic warehouse was realised in October 2021. As project manager and planner, Refolution facilitated the acceptance in just 5 months after initial contact. The two storage rooms each have 185 m³ and 85 m² of storage space. Thanks to the Mirai Intex technology used, the temperature in the storage rooms can be maintained between -90°C and -20°C without any problems. Each room is cooled with an N+1 redundancy of three Mirai Intex MC10 O/W machines using air as the refrigerant. The control quality is +/- 0.5 K with a temperature homogeneity of 2 K in the empty room. This requirement is met at all times thanks to mechanical defrosting. At the same time, the air is dried by reducing the dew point by approx. 15 K. This ensures particularly high product quality during storage. In addition, the speed control enables particularly efficient operation of the systems, even under partial load.

The cooling water systems are realised independently via two redundant R290 chillers (propane chillers) of the STRATOS type from Secon. In addition, the entire installation is protected against power failure by an emergency diesel generator, thus ensuring safe storage at all times.

A cold brine set from Secon is also used to control the temperature of the airlock to -20 °C, which reduces the heat input into the chambers. Thanks to the exclusive use of natural refrigerants, the system is an environmentally friendly, efficient and safe low-temperature storage facility.
