Absorption chillers — cooling powered by heat, not electricity.
LiBr/water absorption chillers use your waste heat, hot water, steam or exhaust gas as the driving energy — delivering chilled water with a fraction of the electrical demand of conventional chillers.
Most popularHot Water Driven
Single and double-effect machines driven by hot water from CHP, district heating, solar thermal or process waste heat.
- Driving heat80–180 °C
- Capacity100 kW – 12 MW
- Typical COP0.7 – 1.4
Steam Driven
Double-effect steam-fired machines for sites with existing steam infrastructure — high efficiency cooling from process steam.
- Driving heatSteam 1–10 bar
- Capacity200 kW – 15 MW
- Typical COP1.2 – 1.45
Exhaust & Direct-Fired
Fired by engine or turbine exhaust, or by gas burner — ideal for trigeneration and off-grid cooling.
- Driving heatExhaust 250–550 °C
- Capacity150 kW – 10 MW
- Typical COP1.2 – 1.4
Cut electrical cooling load dramatically.
Because the compression work is done thermally, an absorption chiller draws only a few kilowatts for its pumps. Where waste heat is available, cooling is produced almost for free — with water as the refrigerant, no F-gas burden, and near-silent operation.
- Displaces electrically driven chiller load
- Water refrigerant — zero ODP, no F-gas compliance
- 25–30 year service life when properly maintained
- Ideal for CHP, district energy, data centres and process cooling
