Two-step Evaporator and Absorber

YORK® YHAU-C Single-effect, Steam Absorption Chillers feature an innovative two-step evaporator design with dual pressure levels, enhancing the absorption process.

 

Chilled water circulates through the evaporators, while a concentrated lithium bromide solution undergoes distillation in the absorber shell, decreasing solution concentration and overall pressure.

Falling Film Generator

Our falling-film generator design offers exceptional heat transfer capabilities, outperforming traditional flooded generators. It not only reduces the needed amount of lithium-bromide solution for circulation but also accelerates start-up from a cold state. 

We use stainless steel tubes to prevent stress corrosion cracking and employ intermediate tube supports, effectively extending the unit's lifespan.
