Ammonia (NH3) 60 % / dimethyl ether (C2H6O) 40 % (mixture) |
System start-up |
2004 |
Kärntnermilch, a big farmers' cooperative with over 3,000 members, operates a modern production plant in Spittal/Drau, Austria. Each year, the plant processes some 74 million liters of raw milk into yoghurt, cheese and other dairy products. |
|
Demands |
To allow the cooperative to environmentally friendly modernise and expand its existing production capacity a spiral freezer for cooling yoghurt using natural refrigerants was needed. |
Solution |
The KWN Engineering-Gesellschaft mbH planned an indirect plant with a compact set of refrigeration units. This marks the first time that an ammonia/dimethyl ether mixture is used as a refrigerant in Austria. |
