They are the devices that help to lower the core temperature of the product in the cold room in a short time without spoiling the product and losing its freshness. This process is also called shocking. Compressors used in shock devices are used with double-stage semi-hermetic and screw compressors.
The most important issue in shock units is the routers. The evaporator blows the air not directly on the product, but on the diverter used. Doing this process helps to preserve the freshness of the product. Suspended and floor mounted type evaporator options are available in shock units.
