Application areas
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:
Slaughterhouses
Poultry industry
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
