The fifth generation of Gram refrigerators utilise CO2 – a natural refrigerant which has zero ozone depletion potential and a positive environmental impact

Hoshizaki is once again leading the way with sustainable refrigeration advances with the development of their fifth generation of Gram refrigerators which utilise CO2 – a natural refrigerant which has zero ozone depletion potential and a positive environmental impact, as Stuart Kayes, technical manager for Hoshizaki UK and fellow of the Institute of Refrigeration (IOR), explains: “CO2 (R744) is a climate-friendly natural refrigerant that plays an important role in many natural and industrial processes.”

In fact, says Kayes, “CO2 is so sustainable that it has a Global Warming Potential of up to 4000 times lower than HFC’s 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.”

Evolving the brand

Simon Frost, director of Hoshizaki UK & Ireland is equally proud to see the Hoshizaki brand evolve in this way and he delights:

“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”

The launch of Hoshizaki’s new CO2 range also aims to educate the industry about long-engrained, often negative conceptions about CO2 as Kayes reflects:

“Hoshizaki are fully aware that many operators will have reservations when it comes to CO2 refrigerants, hence why we anticipate that many will question: How can CO2 refrigerants be climate friendly when we’ve been told for so long that CO2 emissions contribute to global warming?

Well, 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, its 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.

Suitable for connection to a remotely selected and installed CO2 system, all of the cabinets within Hoshizaki’s CO2 range are truly ‘plug in and play’, thus making each refrigerator exceptionally easy to install.
