Ammonia Absorption Machines for Refrigeration and Heating
The sustainable way of cooling and heating
Use (waste) heat to produce temperatures down to -60°C
With ammonia absorption refrigeration plants, cooling temperatures down to -60°C can be achieved by using heat as the main energy source. Colibri b.v. with comprehensive expertise in ammonia absorption technology, can provide all kinds of applications, components, engineering and services. Check what we can offer using the buttons below.
Convert your (waste) heat into cooling capacity
with an ammonia absorption chiller
Using heat as the main energy instead of electricity as in compression machines can be of great benefit. In order to achieve a certain cooling temperature, the heat supply must have a certain minimum temperature. Click the button below and check the possible operating conditions.

Heat as energy input? How does it work?
The first absorption refrigeration machine using ammonia as refrigerant was invented in 1858 by Ferdinad Carré (Wikipedia). The process is still similar today. Understand why a compression machine needs electricity and an absorption machine heat as main energy source.

There is more than just refrigeration
Check other applications for ammonia absorption
Ammonia absorption systems can be also used as heat pumps, heat transformers or in a Kalina cycle. The main purpose can be the use of heat which will be lost otherwise. Look on our page ‘Applications for Ammonia Absorption Machines‘, or use the buttons below.
