ENERGY SAVING EQUIPMENT
Premium Blizzards from Pentland
Hoshizaki Gram goes Superiorplus
T T
he Blizzard Premium refrigerators and freezers are a new addition to the ever- growing Blizzard range of products. In anticipation of the Eco design directive, the project to design a totally new cabinet started over 12 months ago with the brief to produce an energy efficient product able to compete with the traditional high end brands at a much lower cost. The result was demonstrated at the Commercial Kitchen Show in June at the NEC and created a lot of attention.
The cabinets run on hydrocarbon refrigerants and are rated A for the refrigerator with 299kWh/year and B for the freezer with 1065kWh/year.
The sleek aesthetic design and membrane style controller all add to the quality appearance of a product that would not look out of place in the most modern kitchens. The cabinets are feature packed including high efficiency fans and compressors, LED lights, moulded shelf supports for easy cleaning, 85mm insulation and a door and gasket designed to keep heat transfer to a minimum.
Based on an average electric tariff of 10p/ kw typical running costs of the refrigerator are £29.90/year and £106.50/year for the freezer. Using the latest technology, quality materials and manufacturing processes has resulted in an energy efficient product that will contest at all levels, and the pricing is also competitive. Later this year double door versions of both the refrigerator and freezer will be launched to complete the range.

he market is full of refrigeration products that claim to be energy efficient so it is vital for manufacturers to be aware of previous changes made by the industry itself. Hoshizaki Gram UK has always been at the forefront of energy efficient products and carefully monitors, reviews and improves performance with each new generation, to ensure that operators have access to the most advanced energy efficient technology. Gram UK sets its own benchmarks for improvements. An example that the company cites are the improvements in performance and design in the Superiorplus 72, which it says delivers 44% more energy efficient than its Plus 600 (Generation 4) predecessor.
Energy use and therefore running costs, have decreased significantly from 509kWh year to 285kWh. Based on a rate of 10 pence/kWh, the average operator can expect to spend only £28.50 per year on the running costs for the Superiorplus 72. This latest model is also available at the same price as the previous top of the range Gram CX Plus models, so is just as affordable for operators. In addition to low energy expenditure, the hydrocarbon refrigerants present in the Superiorplus 72 have a zero Ozone Depletion Potential and a Global Warming Potential of just three compared to the more damaging HFCs.
Adande’s multi deck displays deliver 50% energy savings
A
fter further independent testing, Adande has confirmed that its Aircell air flow management system, designed for open front multi deck refrigerated retail display cabinets, delivers significant energy savings and tighter operating temperatures compared with conventional refrigerated cases. Adande commissioned Refrigeration Developments & Testing (RD&T) to conduct tests comparing the performance of a 2500mm open front remote multi deck cabinet, commercially available within the UK, with an identical model modified with the Aircell system. The tests were carried out under BS EN ISO 23953 with both cabinets loaded in accordance with the standard. They were run at an operating temperature of M2 (-1°C to 7°C) at an ambient climate class 3 (25°C and 60% relative humidity).
After stable state running for 24 hours, the energy usage of each case was monitored over a further 24 hour cycle. Results for the baseline cabinet showed a refrigeration electrical energy consumption (REC) of 57.61 kWh/24h, compared with a REC of 27.41 kWh/24h for the modified cabinet, representing an energy saving of over
50%. The tests also monitored the temperature of Tylose ‘m’ packs loaded within the cabinets. The temperature of ‘m’ packs in the baseline cabinet varied by 7.7°C, while the temperature of the packs in Aircell cabinet was within a band of just 3.2°C, demonstrating much tighter temperature control. The RD&T data bears out previous independent tests carried out by ECH Engineering which established a REC of 48.00kWh/24h for the baseline cabinet, compared with a REC of 29.72kWh/24h for the Aircell model. In terms of operating temperature variation, ECH Engineering measured a range of pack temperatures of 9.5°C in the baseline cabinet and a band of 3.1°C in the Aircell cabinet.
