YORK® YHAU-CG/CA Double Effect Direct Fired Chiller/Heaters

YHAU-CG/CA direct fired absorption chiller/heaters (120–1,600 TR) use natural gas or light oil to deliver chilled and hot water with a two-step evaporator and absorber design.

Description

Units driven by natural gas or light oil energy sources for commercial cooling and industrial process applications.

Two-step evaporator and absorber design
Parallel flow cycle
Water is the refrigerant

Driven by direct firing of natural gas or light oil, these units provide chilled water and hot water for cooling and heating applications.

Innovative, two-step evaporator and absorber design combined with parallel flow cycle.
Suited for natural gas or light oil energy sources
Variable-frequency drive (VFD) solution pump

Benefits:

Optimal efficiency
- Our YHAU-CG/CA double-effect, direct-fired Chiller uses an innovative, two-step evaporator and absorber design that enhances efficiency.
Flexible design
- Driven by natural gas or light oil energy sources, this unit is suited for a variety of comfort or industrial process cooling applications.
Lower cost of ownership
- World-class engineering and service teams reduce the cost of ownership by simplifying the operating cycle and deliver worry-free peace of mind.

Features:

Two-step evaporator and absorber design enhances absorption of the refrigerant into the concentrated solution, reducing overall pressure
Variable-frequency drive (VFD) solution pump provides superior part-load performance to reduce gas/oil consumption versus constant speed pumps
Control center with graphical, animated, LCD display offers present and past operational status, data recording and chiller safeties accessible at a touch

Simultaneous cooling and heating operation available.
Parallel flow cycle enables lower lithium bromide solution concentrations, reducing crystallization risk and the potential for corrosion
High-temperature generator uses stainless steel tubes to maximize reliability by eliminating stress damage
Isolation valves on the suction and discharge of the solution and refrigerant pumps allow quick and easy servicing of pumps, which typically have a 60,000-hour life
