This unit uses an innovative, two-step evaporator and absorber cycle that is more efficient and more reliable than conventional designs. The flexibility combined with a wide operating envelope is optimally suited for commercial cooling and industrial process applications. Our world-class engineering and service organization helps simplify startup and chiller operation over the life of the system.
Benefits
Optimal efficiency
The York YHAU-C Singe-effect, Steam Absorption Chiller uses an innovative, two-step evaporator and absorber design for enhanced efficiency.
Flexible design
This unit is suited for a variety of steam pressures found in CHP systems, commercial cooling and industrial process applications.
Lower cost of ownership
Our world-class engineering and service teams reduce the cost of ownership by simplifying the operating cycle and deliver worry-free peace of mind.
Two-step Evaporator and Absorber
YORK® YHAU-C Single-effect, Steam Absorption Chillers are uniquely designed with a two-step evaporator that has two pressure levels to divide the absorption process. The chilled water flows in tubes through the two evaporators while a concentrated lithium bromide solution is distilled in the absorber shell-side in the opposite direction. This reduces the solution concentration and overall pressure, making the unit more efficient and reliable than conventional absorption chillers.

Falling Film Generator
The falling-film generator design provides superior heat transfer compared to a conventional, flooded generator. This design also reduces the required amount of lithium-bromide solution to be circulated, decreasing start-up time from a cold start. Stainless steel tubes are adopted to prevent stress corrosion cracking and intermediate tube supports reinforce and extend unit life.
