YORK YZ Magnetic Bearing Centrifugal Chiller is first chiller optimized for ultimate performance with new, low-GWP refrigerant

INDUSTRY.co.id - MILWAUKEE – (Jan. 3, 2018) – Johnson Controls introduces the YORK® YZ Magnetic Bearing

Centrifugal Chiller, the first chiller fully optimized for ultimate performance with a next generation

low-global warming potential (GWP) refrigerant—R-1233zd(E). Chosen for its efficiency, safety,

availability, low environmental impact and cost, nonflammable R-1233zd(E) has an ultra-low

GWP of 1 and is readily available from refrigerant manufacturers.

“We have long led the industry in delivering chiller innovations,” said Laura Wand, vice

president, Chiller Solutions, Building Technologies & Solutions at Johnson Controls. “With the

new YORK® YZ, we have engineered the world’s most efficient low-GWP line of centrifugal

chillers. Our broad range cooling capacity will serve our customers’ many diverse application

needs.”

 

Johnson Controls used a holistic approach to system design and engineering, optimizing every

component around a carefully selected next generation refrigerant for ultimate performance.

The YORK® YZ chiller uses an integral, variable speed drive and advanced magnetic bearing

technology that features a single moving assembly suspended in a magnetic field that does not

require lubrication. This technology requires 80 percent fewer moving parts than traditional oil-

or refrigerant-lubricated drivelines. The result is enhanced reliability, reduced maintenance and

improved efficiency. Compared to traditional fixed-speed oil-bearing chillers, the YZ delivers up

to 35 percent annual energy savings.  

 

The YZ chiller can deliver significant energy savings and lower operating costs by taking

advantage of the off-design conditions where chillers operate 99 percent of the time. The YZ

operates with entering condenser water temperature as low as 40°F (4.5°C), providing

enhanced performance in every operating condition and the widest operating envelope in the

industry. The YORK® YZ uses an optimized single stage design to provide industry-leading real-

world energy efficiency. The chiller can also operate with condenser temperatures below the

evaporator temperatures, eliminating the need for a water-side economizer, which simplifies the

system, requires less mechanical room space and saves money on components, piping,

controls and maintenance.

 

“We continue to deliver industry-leading chiller options that best meet the needs of our current

and continually expanding customer base around the world,” said Bill Jackson, president, Global

Products, Building Technologies & Solutions at Johnson Controls. “The YZ is another fantastic

platform system that equips our customers with environmentally friendly performance in an

optimized solution. Thank you to our YORK® Chiller team for leading the way.”

The YZ chiller brings together groundbreaking YORK®

innovations refined over decades of real world use to create a revolution in chiller design and optimization. It represents a solution from

the chiller experts, who like to think of the YORK® YZ chiller as tomorrow’s chiller, available today
