Star Refrigeration has helped another leading food manufacturer reduce its carbon footprint and “go green” by replacing an industrial refrigeration plant using synthetic refrigerants with a natural refrigerant – carbon dioxide.

Uin Foods is renowned in the industry for creating private label pizzas for the UK’s top retailers, producing 25,000,000 pizzas each year. When the company decided to grow their business through an extension to their production facilities in Glasgow, they relied on Star Refrigeration’s vast experience in industrial cooling to design, build and install a turnkey solution to fit their business needs. 

Star Refrigeration offered a bespoke solution comprising an industrial CO2 refrigeration packaged system and a spiral freezer. When combined, the Star's Envifreeze and the Helix spiral freezer deliver a complete eco-friendly in line cooling solution at a competitive price. The bespoke system is unique in the industry, as it utilises CO2 as a natural refrigerant even though the plant has relatively low capacity.

John Whalen, Managing Director for Uin Foods said, “We are happy with the installation of our new freezer and refrigeration plant. By selecting a modern and energy-efficient refrigeration system which utilises CO2 as a refrigerant, we are further committed to reducing the carbon footprint related to our manufacturing operations. Additionally, we have protected our business against the changes in legislation surrounding HFCs, saving us further time and investment in the future”.

Uin Foods’ pre-engineered packaged system, which is designed to chill or freeze pizza bases with the flexibility to programme up to six different product sizes, provides 200kW of refrigeration capacity at -40˚C. Up until now, those seeking refrigeration solutions in an industrial setting but with a capacity of under 300kW faced something of a conundrum as the F-Gas Regulation is moving end-users away from HFCs while, at the same time, the use of industrial ammonia systems is unsuitable in certain applications due to its capital costs and H&S requirements.

Star’s brand new Envi range of industrial refrigeration packaged systems address the need for a future-proof natural cooling solution, which won’t need to be replaced due to regulations, restrictions or sharp price hikes on certain refrigerants. CO2 is a naturally occurring refrigerant that has a global warming potential of 1 – thousands of times lower than HFCs - and it is non-toxic. It has an A1 safety rating as it is a non-flammable refrigerant with low toxicity, making it ideal for a wide range of applications across all sectors.

David Wallace, Sales Director of Star Refrigeration said, “We are thrilled to be able to provide a bespoke turnkey solution for a well-respected manufacturer such as Uin Foods. Before we launched our industrial CO2 refrigeration packages, there was no clear pathway for businesses which required a capacity of under 300KW but wanted to move to natural refrigerants. Thanks to our in-house design team and specialist technicians, we could deliver this refrigeration and freezing solution in just a couple of months, providing benefits to the customer for many years to come.”

The low temperature Envi range from Star has been developed with the company’s 25 years of knowledge and experience in CO2 . The Envichill, Envichiller, Evicold and Envifreeze systems are efficient and long term industrial solutions for industrial applications.
