CO2 Refrigeration Systems Oxford
MGI Ltd specialises in delivering sustainable and energy-efficient refrigeration solutions for commercial and industrial applications. CO2 (carbon dioxide) refrigeration systems are an increasingly popular alternative to traditional refrigerants like HFCs, offering significant environmental benefits due to their low Global Warming Potential (GWP). As industry leaders, we ensure our clients receive cutting-edge solutions tailored to their unique needs. Book a surveyRevolutionising Refrigeration with CO2 Technology
CO2 is a natural refrigerant with a GWP of just 1, making it a highly eco-friendly alternative to traditional systems. Beyond its environmental benefits, CO₂ refrigeration systems are designed for maximum energy efficiency and safety, ideal for commercial and industrial environments.
Key Advantages of CO2 Refrigeration:
Environmentally Friendly
With a GWP of 1, CO2 is far more sustainable than HFC refrigerants, aligning with stringent environmental regulations.
Energy Efficient
Especially when combined with energy-saving technologies like heat recovery, CO2 systems excel in reducing operational costs.
Safe to Use
CO2 is non-toxic and non-flammable, offering safer operation in commercial and industrial spaces.
Durable and Adaptable
Designed for high-pressure applications, CO2 systems are robust and versatile, making them suitable for a wide range of uses.

Types of CO2 Refrigeration Systems We Offer
At MGI Ltd, we provide tailored CO2 refrigeration solutions to suit the specific needs of your facility. Whether your priority is energy efficiency, environmental compliance, or operational performance, our systems are designed to deliver optimal results. Here’s a deeper look into the three primary types of CO₂ refrigeration systems we offer:
Transcritical CO2 Systems
Transcritical CO₂ systems operate at pressures above the critical point of CO₂ (31.1°C and 73.9 bar). In this state, CO₂ transitions from behaving like a traditional refrigerant to functioning as a supercritical fluid, requiring specially designed components and systems.
- High-Pressure Operation: These systems are engineered for environments where ambient temperatures are high, making traditional refrigeration less efficient.
- Gas Coolers Instead of Condensers: Instead of conventional condensers, transcritical systems use gas coolers to reject heat efficiently, even in warm climates.
- Energy Optimisation: To enhance energy efficiency, these systems often integrate advanced technologies like ejectors, parallel compression, and heat recovery.
- Applications: Ideal for supermarkets, food processing plants, and large commercial buildings located in warmer climates, transcritical systems deliver robust and sustainable performance.
Subcritical CO2 Systems
Subcritical CO systems operate below the critical point of CO, using traditional refrigeration principles with lower temperatures and pressures.
- Reliable in Cooler Climates: These systems are well-suited for colder climates where CO remains in its subcritical state, avoiding the need for gas cooler operation.
- Flexible Configuration: Subcritical systems work seamlessly with conventional refrigeration equipment and configurations, simplifying installation and maintenance.
- Lower Pressure Components: These systems do not require the ultra-high-pressure components necessary for transcritical systems, reducing initial setup costs.
- Applications: Commonly used in cold storage facilities, industrial freezers, and other environments where external temperatures allow for subcritical operation.
Cascade Systems
Cascade CO systems combine the best of traditional and CO refrigeration technologies by utilising two separate refrigerants in a single integrated system.
- Dual Refrigerant Design: In a cascade system, CO is used for medium- to high-temperature applications, while a secondary refrigerant like ammonia or HFCs is used for low-temperature cooling. This configuration allows the system to handle a broader range of temperature requirements.
- Efficiency at Lower Temperatures: By leveraging CO for the medium-temperature stage and another refrigerant for the low-temperature stage, cascade systems achieve exceptional efficiency and performance.
- Reduced Energy Consumption: This setup minimises the energy required for ultra-low temperature applications, such as deep freezing.
- Applications: Ideal for large-scale refrigeration systems, such as those used in supermarkets, industrial manufacturing, and food processing facilities.
Why customers choose MGI
Selecting the right air conditioner installation company affects how well your system performs and how long it lasts. McAlpine Grant Ilco Ltd has installed air conditioning systems across Oxfordshire and other counties for years. Our clients return to us because we complete installations correctly and provide reliable maintenance and servicing afterwards. When we install your air conditioner, we follow manufacturer specifications, test the system thoroughly, and ensure you understand how to operate it efficiently.
Fast response
We respond to service requests within 48 hours. When your air conditioning stops working or performs poorly, we assess the problem on site and explain what needs fixing before we start work. We provide upfront costs and complete most ac repairs during the first visit.
Our experience
Our engineers have worked in building services for over 150 years. This means we can install single air conditioning units in small offices or design multi-zone systems for large commercial buildings. We've handled installations in hospitals, schools, offices, and industrial facilities across Oxfordshire.
