PEACE OF MIND
Low-maintenance, highly reliable and long service life. You can always count on our global service organization to maximize your savings.
Steam Turbine
In the real world, chillers operate nearly 99% of the time at off-design conditions. How a chiller operates at off-design determines actual energy costs. The YST chiller is designed to deliver superior performance at both design and off-design conditions. It's engineered to take advantage of the steam turbine’s inherent variable-speed capability to seamlessly optimize chiller speed and to handle low entering-condenser-water temperatures, allowing the chiller to operate at the highest efficiency.
Modular Configuration
The components of the YST chiller are predesigned to ensure proper fit and prompt delivery. All steam components required to efficiently manage the turbine-exhaust steam are supplied within the chiller package. The YST chiller places the steam condenser on top of the chiller, so the footprint is smaller than competitive steam-turbine-drive chillers and much the same as a compact electrical chiller.
Optiview™ Control Center
At the heart of the system is the OptiView™ Control Center. It offers an industry first – a fully automatic start. Its powerful microprocessor and graphical user interface present more data in the most intuitive way. The large, active-matrix, color screen shows data in relation to illustrations of the key chiller components. In operation, proven OptiView control logic continually monitors all chiller and steam conditions and automatically determines the most efficient way to run the chiller.
