Aerofoil Energy Ltd is an innovative, award-winning technology company focused on improving energy and temperature performance in retail refrigeration. In 2013 the company invented the profiled Aerofoil extrusion that attaches to the end of shelves in refrigerators to save energy. In 2015 we entered into a technical partnership with Williams Advanced Engineering Ltd who bring to bear their engineering expertise and advanced modelling capabilities, complementing our own industry knowledge and understanding of the aerodynamic and thermodynamic properties of commercial refrigeration.

Aerofoil technology addresses one of the most energy-intensive features of grocery retail, by transforming the performance of open-fronted multi-deck fridges. Our Aerofoil product has been rolled out in over 8,000 stores and is helping major UK retailers including Sainsbury’s, Tesco, Asda and M&S to reduce their energy consumption by 20%-25% with commensurate avoidance of CO2 emissions. The Aerofoil product has won multiple awards and in 2021 won the Queen's Award for Enterprise in Innovation.

In 2021, we launched our Elite R&D project, putting together a team of highly skilled practitioners with over 150 years of combined industry expertise. Together with WAE, we have deployed some of the world’s most advanced R&D technologies, including high-fidelity computational fluid dynamic modelling and independent EN23953 laboratory testing. Our suite of Elite technologies addresses some of the key energy performance losses in conventional multi-deck cabinets, as well as developing horizontal innovations for added retail impact.

We maintain a full portfolio of patents, design registrations and trade marks around our intellectual property.

In 2025 we launched 'Invisidoor', an airflow system for open display fridges. Invisidoor replaces costly supermarket fridge doors by enhancing airflow in open fridges to achieve the same efficiency as doors, but without the barrier to sales.
