- Designed for maximum efficiency in the face of real-world variables, where 99% of the cooling season is spent in off-design conditions
- With the OptiSpeed™ Drive, energy consumption can be as low as .20 kW/TR, reducing annual energy costs by as much as 30%
- Earn LEED® Points with credits for Energy and Atmosphere (EAc1) and for Enhanced Refrigerant Management (EAc4)
- Uses zero-ODP, R-134a or R-513A refrigerant
- Industrial, reliable, long-lasting proven design
- Custom multi-stage chiller with flexible options of steam turbine or electric motor with variable speed drive
- Innovative YORK® two-step evaporator and absorber design enhances absorption of the refrigerant into the concentrated solution, reducing overall pressure and risks of crystallization.
- Lower pressure steam into the generator can be used to drive the absorption cycle for higher system efficiency.
- Solution plate heat exchanger optimizes efficiency by enabling effective heat transfer between the diluted and the concentrated lithium-bromide solutions.
- Two-step evaporator and absorber design enhances absorption of the refrigerant into the concentrated solution, reducing overall pressure.
- Parallel flow cycle enables lower lithium bromide solution concentrations, reducing crystallization risk and the potential for corrosion.
- Variable-frequency drive (VFD) solution pump provides superior part-load performance to reduce steam consumption versus constant-speed pumps.
