Refrigeration specialist Adande has commissioned independent tests of its Aircell air flow management technology to measure temperature control.
The company says the research confirms that Aircell delivers more accurate holding temperatures compared with conventional open-fronted refrigerated multi-deck cases.
The results show that it is able to maintain the quality and appearance of chilled food over longer periods, the company said.
Testing was carried out under BS EN ISO 23953, the industry standard for the testing of refrigerated display cases.
A conventional open-fronted multi-deck case was tested alongside a similar model, modified with the prototype Aircell air flow management technology.
Both cases were run at operating temperatures of 3M1: -1 to +5o C, at an ambient of 25o C and 60% relative humidity. After stable state running for 24 hours, the temperatures in each case were monitored over a further 24 hour cycle.
The case modified with the prototype Aircell system demonstrated a temperature fluctuation of just 2.8o C (+2.1 to +4.9o C), whilst the conventional case had an 11o C variation (+2 to +13o C).
“Aircell is being developed to offer retailers several benefits over conventional open front multi-deck cases,” said Adande chairman Nigel Bell. “Significantly less energy consumption will provide operational cost savings, whilst the maintenance of perishables at optimum quality and appearance will reduce the amount of chilled merchandise, which is price discounted or thrown away.”
Aircell works by dividing the case’s merchandising envelope into separate air flow managed cells with small, low pressure air columns.
Each cell has its own air curtain, which is 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 from the case.
