Forward. Naturally. With industrial CO₂ refrigeration solutions

How large CO₂ solutions will benefit Industrial Refrigeration

Use the parts designed for the job. Danfoss’ built-for-purpose, built-for-industry, transcritical CO₂ solutions ensure your operation is future-proof. The larger components bring unmatched efficiency and simplicity to large systems. Creating a new industrial standard for transcritical CO₂ systems.

Transcritical simplified. Start your complexity-free journey in natural refrigerants with Danfoss.

Cool responsibly

CO₂ is a sustainable, natural refrigerant that, compared to F-gasses, delivers strong benefits in industrial applications. With zero ozone depletion and a GWP of only 1, CO₂ refrigeration has a low environmental impact and works in any climate at a large scale.

Develop your business

The choice of refrigerant and system design can directly benefit your business and your bottom line. Not only can CO₂ systems provide great energy efficiency and options for heat recovery, but they are a future-proof application and a sustainable platform for an evolving business.

Solutions for sub- and transcritical CO₂ in industrial refrigeration

CO₂ in industrial refrigeration is used either as the low-stage refrigerant in cascade installations, or as a secondary coolant. With the introduction of larger compressors with high working pressure, CO₂ also begins to be used on the high stage in CO₂ transcritical systems.

Danfoss has more than 20 years of experience in developing industrial solutions for CO₂ systems and offers a complete range of valves and controls for sub- and transcritical applications, including:

Control valves
Line components
Complete valve stations
Filter-driers
Sensors for temperature, pressure, level and gas detection
Controllers

Most recently, Danfoss has launched the 140 bar Shut-Off valve SVA-140B, Strainer FIA-140B and Service needle valve SNV-140B and more will come.

Danfoss has carried out all the required tests to ensure that components released for use with CO₂ at high pressure levels are compatible in all respects. Danfoss industrial refrigeration specialists can help you with the selection of the right components for CO₂ applications.

We have developed several tools that facilitate design of CO₂ systems such as Coolselector^®2, application guides and a comprehensive set of technical leaflets and instructions.
