Large ammonia refrigeration systems contain up to 60,000 kg of refrigerant. Installations for food processing and INDUSTRIAL plant refrigeration typically range from 5 to 100 tonnes. Around the world large R717 systems are subject to increasingly stringent safety REGULATIONS and pressure is being placed on companies to reduce the size of ammonia refrigerant charges. Therefore, owners of large industrial plants are starting to use ammonia in CONJUNCTION with a secondary refrigerant such as carbon dioxide (R744) or potassium acetate, meaning that an up to 90% reduced ammonia charge is needed compared to an ammonia-only system. The reduction of charge does not lead to any PERFORMANCE COMPROMISES.
