Johnson Controls presents new centrifugal magnetic bearing Chiller

International. Johnson Controls presents the York YZ centrifugal magnetic bearing Chiller, which they call the first chiller fully optimized for maximum performance with the new refrigerant R-1233zd (E) which is of low global warming potential (PCA).

The company explained that the R-1233zd (E), has been chosen for its efficiency, safety, easy availability, low environmental impact and cost, being non-flammable has the lowest PCN of 1 and is easy to get with the manufacturers of refrigerants.

"We have a long history in the industry, offering the greatest innovation in chiller design," says Laura Wand, vice president of Chillers Solutions, Building Technologies & Solutions at Johnson Controls. "With the new York YZ we have developed the world's most efficient line of low-GWP centrifugal chillers. With our wide range of cooling capacities we can meet the most diverse needs of our customers' applications. "

For the design and development of the system, Johnson Controls used a comprehensive approach, optimizing each of the components around this latest generation refrigerant being carefully selected to achieve maximum performance. The York YZ Chiller uses an advanced advanced technology of variable speed drives and magnetic bearing with which a single mobile system is obtained suspended in a magnetic field, which does not require lubrication.

This technology requires an 80 percent less moving parts than traditional transmission systems lubricated with oil or coolant. The result is greater reliability, less need for maintenance and better efficiency. With the YZ it is possible to achieve annual energy savings of up to 35 percent compared to traditional oil-lubricated bearing chillers.

With the YZ chiller significant energy savings and lower operating costs are achieved, taking advantage of the unforeseen conditions of use under which the 99 operate chillers. The YZ works under conditions of incoming water temperature to the condenser as low as 4.5 ° C (40 ° F), achieving the best performance under any working condition and widest operating range in the industry.
