The New Cool

Revolutionizing Commercial Refrigeration.

The Copeland CO₂ scroll solution for booster systems.

Innovation is key to meeting the regulatory challenges and consumer trends of commercial refrigeration. Copeland engineers have developed an innovative solution based on several patented technologies, to help solve these economic and ecological challenges, resulting in the industry's most anticipated innovation.

Copeland CO₂ scroll technology is a game-changer for commercial refrigeration. The entirely new CO₂ transcritical scroll compressors are taking sustainable refrigeration a big step forward. These compressors feature Dynamic Vapor Injection (DVI), which enables a smoother and more efficient operation of CO₂ booster systems in all climates, while keeping costs low.

Can Technology Give You Peace of Mind?

Five success factors making the Copeland CO₂ scroll technology unique.

• Low operating costs in all climates due to Dynamic Vapor Injection (DVI).
• One booster design fits all climates without the need for parallel compression.
• Enables the most compact and lightest system for applications with limited space availability.
• Ensures the highest system reliability in all ambient temperatures.

Strong and Smart.

Deal with Flash Gas in a New Way!

The game-changing Dynamic Vapor Injection technology.

The new Copeland CO₂ transcritical compressors feature Dynamic Vapor Injection (DVI). DVI allows for flash gas to be directly injected from the economizer or the flash gas tank into the compressor through a check valve. This innovative concept enables a more efficient and smoother operation of CO₂ booster systems in any climate, making CO₂ more attractive than ever as the refrigerant of choice. Indeed, DVI technology reduces the system's complexity, eliminating the need for parallel compression.

Copeland CO₂ scroll technology reduces the overall system complexity significantly, which also leads to reduced applied costs through:

• Easier installation and maintenance.
• Fewer components (no additional parallel compressor and drive needed).
• Simplified piping system.
• Smaller rack in size and weight.

Stay Cool. And Calm.

Smart, safe, and silent.

Copeland combined this new generation of CO₂ scroll compressors, equipped with DVI, with a suite of intelligent electronics to create a unique solution for CO₂ boosters with optimized system performance.

At the heart of this solution: the new Copeland XC Pro CO₂ scroll controller, specially designed for the booster application. Its smart control logic manages the suite of intelligent electronics; it monitors, analyzes, and optimizes the different system components to deliver high system efficiency and safe compressor operation; and enables lower pressure design.

Copeland CO₂ scroll compressors run very smoothly and quietly because of their continuous compression process, resulting in less vibration (safer for high-pressure systems). They are available in fixed and variable speeds, which allows for more flexibility and high efficiency thanks to the brushless permanent magnet (BPM) motor technology, in combination with efficient drives. This results in the compressor always operating at optimal speed, rendering inefficient on-off operations obsolete.

Success Comes in Circles – The Perfect Booster System.

Designing a booster system with the Copeland CO₂ scroll solution.

It's the beginning of The New Cool. Our new CO₂ solution integrates high-quality components with a smart electronic concept that makes commercial refrigeration with CO₂ less complex and easier to maintain. It reduces both investment and operational costs, lowering total cost of ownership.

The basis of all these improvements is Dynamic Vapor Injection (DVI) technology. It allows the elimination of system components such as the parallel compressor or the inverter drive and also reduces the amount of piping required. As a result, the booster circuit is not only less complex compared to standard boosters, but also less prone to faults. Thanks to pre-configured electronics, it is also easier to set up and operate. Combined, these features lead to smoother and more efficient operation of CO₂ booster systems in all climates while keeping costs down.

Efficient Cooling at +44°C? Challenge Accepted.

Your solution for efficient and reliable refrigeration.

The warmer the climate, the greater the challenges of CO₂ refrigeration, as the complexity of the system increases to achieve acceptable efficiency. Copeland CO₂ scroll DVI technology eliminates the need for specific designs for most European climates, but still delivers system efficiency at the highest level. The integrated advanced electronic concept with preconfigured and perfectly matched compressor, sensor, and valve parameters further enhances the system's simplicity and therefore delivers an efficient and reliable operation. The CO₂ scroll compressors' low vibration levels and a simple oil management circuit further contribute to this effect.

Flexibility Runs in the Family – Compressor Line Up.

A tailored solution for every application.

Copeland's brand-new compressors with CO₂ scroll technology provide higher efficiency and reliability in commercial refrigeration. The new portfolio comprises CO₂ compressors for a range of applications from convenience store to small supermarket. The three line ups form the broadest portfolio of CO₂ compressors available on the market:

• Copeland ZT/W CO₂ transcritical scroll compressors for medium temperature (standstill pressure of 110 bar).
• Copeland ZL/V CO₂ subcritical scroll compressors for low temperature (standstill pressure of 110 bar).
• Copeland ZO/V CO₂ subcritical scroll compressors for low temperature (standstill pressure of 45 bar).

A Giant Step for a Smaller CO₂ Footprint.

Copeland CO₂ scroll solution provides answers to the industry's biggest challenges – and makes the natural refrigerant widely available.

The F-Gas regulation is one of the dominant challenges of the refrigeration industry today, posing new limitations on the choice of refrigerants and impacting system architecture. As the phase down of HFCs continues globally, the challenge is to identify truly sustainable alternatives that maximize the environmental, economic, and operational benefits. This is where our CO₂ solution comes into play. It is a climate-neutral solution that can be used highly efficiently - today and in the future.

CO₂ is the refrigerant of choice due to many benefits and its continued success as a leading refrigerant is now being driven further by a technological leap. As the market leader in scroll technology, we at Copeland have succeeded in perfectly combining scroll technology with CO₂ for medium- and low-temperature applications, thus making the best of both worlds widely available.

CO₂ as a refrigerant offers many advantages:

• It's future-proof.
• It's non-flammable.
• It's non-toxic (when industry standards and best practice rules are followed).
• It's climate friendly (global warming potential is 1 GWP=1; its ozone depletion potential is 0 ODP=0).
