CO2 Chillers

A comprehensive range of chillers operating on CO2 refrigerant, ideal for low temperature applications.

About CO2 Chillers

Aqua’s CO2 chiller range covers capacities from 6kW to 1MW. Units can be water or air cooled and can achieve temperatures as low as -37°C. CO2 chillers are ideal for applications requiring ultra-low temperatures, with the bonus that carbon dioxide is a completely natural refrigerant.

How CO2 Chillers Work

Carbon dioxide chillers – or CO2 refrigeration systems – work by using carbon dioxide (CO2) as the refrigerant to cool the process. They use the principles of thermodynamics and the vapor compression cycle to operate. They are highly reliable, as well as being an efficient and sustainable choice.

As a refrigerant, CO2 has excellent physical properties and a low critical temperature point when compared to other popular refrigerants. This critical point allows the chillers to operate efficiently at low temperatures, especially when requiring sub-zero temperatures.

In addition, CO2 is a natural refrigerant, with zero ozone depletion potential (ODP) and a global warming potential (GWP) value of just 1. CO2 chillers will minimise carbon impact far more than any synthetic refrigerants are able to, future proving your business for the long term.

CO2 chillers are commonly used for low temperature applications within the food, pharmaceutical, biotechnology, oil & gas, and research & development sectors.
