Adande has commissioned Bristol-based testing house Refrigeration Developments & Testing (RD&T) to carry out independent tests comparing the performance of Adande drawers to Foster-Flex drawers.
Both Adande and Foster claim that their drawers offer customers useful storage in preparation areas with the ability to vary and control temperature.
Furthermore, both companies claim that their drawers are energy efficient.
Adande asked RD&T to independently test both these drawers to the appropriate European standard.
RD&T tested one new drawer from each company; an Adande VCS R2 and a Foster FFC3-1. Both were tested as chillers and then as freezers.
All tests were carried out to the new European wide test standard for foodservice cabinets; prEN16825:2015(E).
RD&T focused on the drawers’ capacity, whether they hold temperature when opened and how much energy they use.
The results are said to show that an Adande drawer offers 18% more storage volume than a Foster drawer.
Set as a freezer, with a set point of -20°C, all measured test packs in the Adande drawer operated between -18.2°C and -20.6°C, demonstrating the stable temperature which is a feature with the Adande design.
In the Foster drawer, with a set point of -23°C, the measured packs operated between -14.3°C and -23.0°C.
RD&T noted that the compressor ran constantly in the freezer mode indicating that further reduction in internal temperature with different settings was unlikely to be possible.
The European test standard requires that in a freezer no measurement test pack (Mpack) can be warmer than -15.0°C (L1). If a pack is warmer than -15.0°C during the test the freezer does not pass the test.
Adande said that the Foster drawer did not pass but the Adande drawer did.
As a fridge, with a set point of 3°C, all measured test packs in the Adande drawer operated between 2.8°C and 4.1°C.
The Foster drawer had a set point of 0°C. However, during the test the measured packs operated between 1.0°C and 8.0°C.
The European test standard requires that in a fridge no measured pack can be warmer than 5°C (M1). If a pack is warmer than 5°C the fridge does not pass the test.
Again, Adande said that the Foster drawer did not pass this part of the test but the Adande drawer did.
Both units were tested in terms of their annual energy consumption (kWh/year). RD&T claims to have found the Adande drawer to be far more energy efficient than the Foster drawer.
As a chiller Adande’s drawer used the equivalent of 306kWh/year, whereas the Foster drawer used the equivalent to 1,018kWh/year, despite the highest test pack temperature being 3.9°C warmer.
As a freezer the Adande drawer used the equivalent of 761kWh/year; whereas Foster drawer used the equivalent of 1,970kWh/year.
Nigel Bell, executive chairman of Adande, commented: “These results clearly demonstrate why customers should choose Adande.
“Our drawers offer better storage space, hold temperature and save energy. They do that by using our patented “hold the cold” technology which is fundamentally different.
“Other drawers might look like an Adande but unless they use our technology they will not give customers the same benefits.
“In 2014 RD&T independently compared our drawers to those offered by Precision, with very similar results and the same conclusion.”
