Honeywell Solstice® ze Food Beverage Sustainability Case Study
Meeting Common Global Warming Obligations“The company leaves no stone unturned and every year invests significant resources in the testing and industrialisation of new, increasingly environmentally-friendly machines. Where we see opportunities to mitigate our environmental impact – for example in the use of new refrigerants – these will be carefully considered and analyzed for the contributions they can make to a sustainable future.” Luca Faedi, Responsible for Production and Technical Department
Creating a Cleaner FutureThe Celli water dispenser using Honeywell’s Solstice ze was first exhibited at the Mostra Convegno in Milan (Italy) in March 2012 – plans are now well advanced to demonstrate the refrigerant’s effectiveness in soda and beer coolers at a number of upcoming shows. Celli’s adoption of this technology reflects growing demand in the Food & Beverage market for the application of refrigerants with low GWP, energy efficiency and reduced carbon emissions in a global (all regions, all climates) and sustainable way. The table below illustrates the relative merits of refrigerants current in use in the F&B industry.
Reducing Emissions through Life Cycle Thinking
In just a few decades, Celli SpA has become the leading designer and manufacturer in Italy of refrigeration and dispensing systems for beer, soft drinks, wine and water. The company is an acknowledged leader in Europe and around the world both for its products – which it exports to 86 countries – and for its commitment to minimizing environmental impact, which is enshrined in a green program called Life Cycle Thinking. The company’s products and systems are produced in San Giovanni in Marignano, where it operates a policy of continuous innovation and originality. The success of this industrial-oriented philosophy is expressed through the relentless pursuit of quality, made possible through investment in advanced technologies and in its people. In keeping with its environmental commitments, Celli recently worked with Rivoira (Praxair Euroholding) to introduce Honeywell’s Solstice ze refrigerant (HFO1234ze) as a globally compliant replacement for R134a in beverage dispensers. A field test involving the Celli Brave 30ES – with a Secop (formerly Danfoss Compressors) NL10MF compressor – compared the performance of Solstice ze against R134a, which had previously been specified by the company. Solstice ze is a refrigerant based on hydro-fluoro-olefins (HFO) with a Global Warming Potential of just 6 and an atmospheric lifetime of 18 days – compared to measures of 1430 and 13 years respectively for R134a.Summary of Field Test Results:
- Solstice ze delivered a 99.5% direct comparative emissions reduction over R134a
- Solstice ze exhibited lower discharge pressure (around 40% versus 134a), thereby reducing compressor mechanical stresses
- Solstice ze proved to be a near drop-in replacement for R134a, ensuring full optimization of current equipment
