Features

  • Variable-speed driver delivers superior performance at both design and off-design conditions for higher efficiency
  • Modular configuration provides maximum flexibility, customization and compact footprint
  • Low noise as chiller operates at significantly reduced sound levels compared to many electric chillers
  • Application flexibility of the chiller handles a wide range of leaving- and entering-chilled-water temperatures, fluid flows and steam conditions
  • Mix-and-match components ensure proper fit and prompt delivery
  • OptiView™ Control Center displays steam conditions and automatically determines efficiencies by presenting more data in the friendliest possible way

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.
