Waitrose has commissioned an Isentra CO2 refrigeration system as part of a full suite of systems provided by DD Cooling to operator Wincanton at its new customer fulfilment centre in West London. Thanks Food & Drink Tech for the coverage! foodanddrinktechnology.com/news/37937/wai…

“Waitrose has been employing natural refrigerants to minimise its environmental impact for many years and the Greenford project extends the retailer’s existing CO2 portfolio." Read Cooling Post to see how our systems are helping Waitrose deliver more: coolingpost.com/features/co2-s…

Last year, Isentra systems were installed at food wholesaler Brakes' Norfolk and Wales depots to help targets to lower carbon emissions by 30% by 2025. Find out more: bakeryandsnacks.com/Article/2020/0…

Waitrose specified a highly resilient refrigeration requirement, so each CO2 system was fitted with our Full Resilience option, which includes back-up controls and standby pressure regulators. Read more in ACR News: acr-news.com/waitrose-opts-…

The world’s biggest CO2-based heat pump has been commissioned by a Danish utility supplier. The 50MW pump will provide heating to 100k people and help the city of Esbjerg be carbon neutral by 2030. Do you think UK utilities providers will follow suit? coolingpost.com/world-news/dh-…

Ammonia has an important role in food production and other process cooling applications. This will continue long into the future. However, I believe transcritical CO2 systems will overlap more deeply into the traditional ammonia space than HFC systems ever did. Do you agree?

The success of CO2 is easy to understand when you consider it is non-flammable, non-toxic, cheap, freely available, planet-friendly and - last but not least - has excellent refrigerant properties. Have you explored the benefits of CO2 refrigeration?

There is no such thing as a perfect refrigerant; it's all about playing each technology to its strengths. Would you agree with this statement?

The question "which is more efficient: ammonia or CO2?" can't be answered in one sweeping answer. Any refrigeration system's efficiency depends on many factors including application, design, condition and operation. What are your thoughts on this?

Almost every refrigeration solution is different dependent on the end-users' requirements and geography; there cannot be a definitive answer to the question of energy efficiency. Do you agree?

We must remember that the efficiency of a refrigeration solution has to be considered over a period of 365 days. Do you factor this into your decision-making process when investing in a new refrigeration solution?

Transcritical CO2 will become more prevalent in mid-sized applications often served by smaller ammonia systems. This is a market development driven by cost, risk and the option to maintain simpler and efficient direct cooling with higher charge applications. Do you agree?

These are revolutionary times for refrigeration. It's severed by two natural refrigerants unlikely to come under environmental scrutiny and free us from further phase-out legislation that's have dogged us for decades with the CFC, HCFC and HFC synthetic variants. Thoughts?

There is room for ammonia and CO2 in refrigeration: it's a matter of playing each of them to their advantages. Do you agree? What are your thoughts on this?

Ammonia will go unchallenged in the upper capacity echelons of the industrial refrigeration sector, or certainly until someone develops a transcritical compressor that squares up. I feel this is some way off, do you?

We’re bringing CO2 into force as the prime agent of change in maximising the efficiency of refrigeration systems and minimising refrigeration’s impact on the environment. Our new facility helps us deliver now for the future global agenda. acr-news.com/isentra-opens-… ACR News

Relying on F-Gases poses many risks to businesses: ⚠️ Imminent F-Gas legislation review ⚠️ Availability – no guarantee of future HFC supplies ⚠️ Price uncertainty + volatility ⚠️ HFC quota tapers DM me for help mitigating these risks. #foodproduction

The skills our sectors have honed as #refrigeration and #airconditioning engineers will be in high demand as the UK government supercharges #netzero plans. Do you think our industry appreciates the scale of what's in front of us? And are we ready to adapt? #decarbonisation
