Star Refrigeration's Envifreeze: CO2 Refrigeration for Industrial Applications

Star Refrigeration introduces its Envifreeze range of industrial CO2 packaged solutions, aimed at industrial applications below 300kW, to meet evolving F-Gas regulations and sustainability demands.

The new CO2 packaged solutions cater to temperature-controlled storage, food and drink manufacturing, inline freezing and chilling, building services, industrial processes, data centres, and leisure and ice applications. According to Star Refrigeration, this move aligns with current environmental standards, as companies seek future-proof and sustainable cooling technologies.

The product line includes:

• EnviChill: For temperature-controlled storage between 0°C and 8°C.
• EnviCold: Suited for storage applications ranging from -22°C to 0°C.
• Envifreeze: A two-stage transcritical plant designed for food production and storage between -40°C and -20°C.
• EnviChiller: For a range of chiller applications.

Star Refrigeration highlights the environmental benefits of CO2: it has no effect on the Ozone layer and possesses a global warming scope (GWP) of one – thousands of times lower than synthetic refrigerants. The company states this makes their CO2 solutions a reliable, long term and future-proof option, unaffected by the EU F-Gas Regulation (517/2014) and the Kigali Amendment to the Montreal Protocol. The company also notes the A1 safety rating.

As a low-GWP natural refrigerant, CO2 is unaffected by HFC restrictions. Star Refrigeration has over 25 years of CO2 experience, providing total CO2 project solutions. Further information can be found on Packaged Refrigeration Systems.

Increasingly stringent environmental legislation sees operators of refrigeration systems under increasing pressure to reduce or eliminate their use of traditional, high-GWP refrigerants. This is highlighted by the revised EU F-Gas Regulation (517/2014), which will see the availability of HFCs reduced by 79% between the years of 2015 and 2030, whilst simultaneously introducing step-wise bans on the installation and servicing of systems using higher-GWP refrigerants. In addition, the Kigali Amendment to the Montreal Protocol, agreed in 2016, saw 197 countries across the globe commit to cutting the production and consumption of HFCs by more than 80 percent by the year 2047.

For industrial processes under 300KW there is no pre-engineered, industrial CO2 refrigeration packaged alternative – until now, says Star Refrigeration. Their new range aims to provide a high performance, resilient and a long term solution for smaller scale industrial applications.
