Hoshizaki has unveiled the “next step” in its sustainable refrigeration programme with the launch of fifth generation Gram fridges.
The units utilise CO2, a natural refrigerant which has zero ozone depletion potential and a positive environmental impact.
Stuart Kayes, technical manager for Hoshizaki UK, said: “CO2 (R744) is a climate-friendly natural refrigerant that plays an important role in many natural and industrial processes. In fact, CO2 is so sustainable that it has a Global Warming Potential of up to 4,000 times lower than HFCs such as R404a – an environmentally damaging refrigerant which has now been banned from use in new commercial equipment models.
“By integrating CO2 into Gram’s award-winning refrigeration line-up, Hoshizaki are now able to offer a range of refrigerators that boast a positive environmental impact.”
Mr Kaye said he was aware there are long-engrained, negative perceptions about CO2 refrigerants, especially as operators have been told for so long that CO2 emissions contribute to global warming.
“The first step to answering this question comes through clarifying that Global Warming Potential (GWP) is a relative measure of heat-trapping impact. For example, Greenpeace states that the commonly used HFC R134a has a 20-year GWP of 3,830; thus one kilogram of R134a is as harmful to the environment as 3,830 kilograms of CO2 equivalent (CO2e) over 20 years.
“Thus, when you do the maths and breakdown the facts, it’s clear to see that CO2 is the superior, more sustainable option. Offering excellent thermophysical and heat transfer properties, CO2 is also one of the most practical and safest refrigerants available to the industry.”
Simon Frost, director of Hoshizaki UK and Ireland, said: “The launch of our Gram CO2 cabinets truly marks the next step in sustainable refrigeration developments. It gives our customers a viable alternative to HFC models and ensures they are perfectly placed to be compliant with the latest EU F Gas Regulations.”
