Advancing efficiency by design
York YHAU-CL/CH Single-effect Hot Water Absorption Chillers offer a broad range of capacity from 30 to 2,000 TR. This unit uses an innovative two-step evaporator and absorber cycle that is more efficient and reliable than conventional designs. Its flexibility combined with a wide operating envelope utilizes waste heat as low as 70°C. Our world-class engineering and service organization helps to simplify start-up and chiller operation over the life of the system.
Benefits
Optimal efficiency
York YHAU-CL/CH Single-effect Hot Water 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 operating cost
Reduced hot water flow rates and pumping energy help achieve lower costs of operation.
Two Step Evaporator and Absorber
YORK® YHAU-CL/CH Hot Water 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.
