A forecourt in Longford, Ireland, has reported a 35% boost in beer sales after installing a new ‘invisible air door’ in its beer cave.
Hanlon’s Gala has become the first retail store to install an AirDoor Curve, designed by former F1 engineer Nick Wirth and his company Wirth Research.
The technology uses “sophisticated aerodynamics” to create an ‘invisible door’, helping to keep cold air inside the beer cave while preventing warm air from entering.
Store owner Patrick Hanlon said he sold 35% more beer in July compared to the same period in 2024, thanks to the installation.
He attributed the uplift to being able to keep the entire beer range chilled, while the “lack of a physical door has created a more inviting atmosphere”, said Patrick.
The system is also designed to cut condensation, reducing the risk of stock or refrigeration pipes from freezing.
“This technology has really helped our store to stand out, as we are the only store with this AirDoor Curve technology,” said Patrick.
“Being the first of its kind, I have been blown away by the increase in beer sales, especially during the summer months. Being able to sell the larger cases of beer really helps our store to stand out.”
The technology requires “no extra energy costs”, claimed Wirth Research, and uses no heating or cooling components.
“It takes early adopters like Hanlon’s Gala to show that these types of products deliver such a solid ROI. Refrigeration remains a major source of energy usage for retailers,” said Wirth.
”We want to prove that we can create products that use less energy and also improve customer comfort, and ultimately sales.”
