Adande parent company feels it has solved display case debate

The open front refrigerated multi deck cabinet is the preferred option for the display of chilled goods.

Adande Refrigeration’s parent company, Applied Design & Engineering, believes it can assist in the food retailing industry’s aim to reduce energy consumption.

With multi-deck refrigeration cabinets historically deployed as the solution for the display of chilled goods, they can spill dense cold air into a store’s aisle, increasing energy usage.

Applied Design & Engineering’s MD Ian Wood believes that its Aircell system, which has been designed to be incorporated within newly built equipment, could be the solution.

It works by dividing the refrigerated display case’s merchandising envelope into separate air flow managed cells with low pressure air columns. Each cell has its own air curtain, which is said to be more efficient than a full case height air curtain on a conventional multi deck case.

The net result is less pressure on the air curtain of each cell and a ‘substantial’ reduction in cold air spillage, creating claimed energy savings of over 30% compared with conventional open front cabinets.

Aircell is also said to maintain accurate operating temperatures, within a tighter bandwidth, to keep food at optimum appearance, safety and quality over extended periods. All this is achieved whilst maintaining the preferred open front format.

Wood commented: “Understandably, many OEMs have engineered glass door cabinets to meet the BS EN ISO 23953 specification of 10 door openings per hour.

“However, the evaporators specified are not capable of dealing with the higher infiltration loads associated with more frequent door openings. This results in iced evaporators and a loss of temperature control or more frequent and harsher defrost cycles with increased energy consumption.

“Our tests clearly demonstrate that glass doors cabinets, designed for 10 openings per hour, experience significant loss of temperature control at an opening frequency of 30 openings per hour or more.”

He concluded: “The holy grail for retailers is an open front cabinet for high visibility of merchandise and ease of browsing and shopping, combined with significant energy savings and accurate and stable temperature control.

“Cabinets with doors do not meet these criteria and shelf edge technology does not deliver sufficient energy savings or meet the needs for accurate control of operating temperature.

“In my opinion the only technology currently available which fits the bill is the Aircell air management system. We will continue to support the drive for the development of disruptive technology, which lowers energy consumption and reduces food waste.”
