YORK Refrigeration's standard programme ofpackaged ammonia chillers comprises more than 20 optimized models and can be supplied with capacities ranging from approx 90 to 2,700 kW when chilling water from 12 to 6C.Tailor-made solutions can be supplied with capacities up to approx 8,000 kW. > Some ofthe most common application areas include: > Dairies,breweries,wine production Ice rinks YORK Refrigeration has developed a comprehensive seriesofpackaged ammonia chillers based on what is probably the largest and most versatile programme ofreciprocating and screw compressors. The chiller series is used in industries where indirect cooling is required by means ofa secondary refrigerant.YORK Refrigeration's packaged ammonia chillers have anumber ofoutstanding features which make them the ideal choice for a wide range ofliquid chilling purposes: > Process cooling in chemical and pharmaceutical production facilities > Cold and frozen storage > Concrete mix cooling.The chiller packages are supplied on a common base frameincluding all components necessary for start-up and operation. A trial run with ammonia ensures trouble-free start-up on site.The chillers consist ofthe following main elements: > Flooded design ensures very high COP values, even at part load conditions > Ammonia - the most environmentally friendly refrigerant - is used on all models > Extremely low refrigerant charges ensuring operational safety > YORK Refrigeration reciprocating compressor > Plate heat exchanger as evaporator and condenser > Unisab II - the most advanced control and monitoring system on the market - is used on all the ammonia chillers > Unisab II computerized control and monitoring system > Electric switchboard with Y/D starter for compressor drive motor > A compact design ensures easy and trouble-free installation > An automatic oil return system ensures continuous, trouble-free operation > Automatic oil return system > Plate heat exchangers (evaporator and condenser) of stainless steel ensure long life and trouble-free operation > All necessary automatics and valves > DS 320,SA,TV,SDM and ISPESL approvals as standard. Others on request > The design ofthe plate heat exchangers prevents any internal leak and thus makes it possible to carry out direct cooling ofbeer and milk. > Insulation ofseparator and cold pipes with polyurethane cladded with aluminium sheet > First oil charge (Synthetic). >
