Dunham-Bush Industrial Chillers ABS-HW/EX

Dunham-Bush Absorption Chiller — Hot Water & Exhaust

Series: Absorption Series

Waste heat recovery cooling — hot water or exhaust gas driven for co-generation plants

Product Overview

The Dunham-Bush Absorption Chiller is designed for industrial waste heat recovery, operating on hot water or exhaust gas from engines or turbines. Eliminates mechanical compressor electricity consumption — the chiller is driven by thermal energy that would otherwise be wasted. Ideal for co-generation (CHP) plants, large manufacturing units, and facilities with process steam or exhaust gas availability. Provides superior energy recovery and cooling performance with dedicated maintenance and engineering support.
