led to the pioneering work of Ian Wood in the development of the insulated horizontal container technology, subsequently patented by Adande. The horizontal container system works on the principle that cold air is denser than warm air, all but eliminating cold air spillage even after frequent and prolonged openings. This means that cold air is retained within the drawer, reducing duty and energy consumption, whilst maintaining accurate holding temperatures. Lower energy consumption helps reduce operators’ carbon footprints and, of course, save money on energy costs. In ‘like for like’ metred energy tests in working kitchen environments, it has been demonstrated that horizontal container type refrigeration can deliver 57% energy savings compared with conventional upright cabinet refrigerators.
Life cycle cost
Many end users are now viewing overall product life cycle cost as fundamental to their sustainability commitments. It is incumbent upon our industry to meet these demands by innovative re-engineering of refrigeration products. We must continue to incorporate state-of-the-art components, such as energy optimised compressors, EC fans and more sophisticated controllers, for extended life cycle, reduced maintenance and lower operating costs. The industry also has a responsibility to ensure that refrigeration products are fully recyclable at the end of their product life, rather than being disposed of in landfi ll.
The choice of refrigerant is also a topical issue, which OEMs need to address. There is a distinct trend towards the use of hydrocarbon refrigerants, such as R600a, which has negligible ozone depletion characteristics and a very low global warming potential. Equipment operating on hydrocarbon options, requires a signifi cantly smaller refrigerant charge, reducing system pressures for less duty on the compressor and a longer life cycle.
Reducing food waste
EC Regulation 852/2004 and The Food Safety and Hygiene (England) Regulations 2013 state that foods likely to support the growth of pathogenic micro-organisms or the formation of toxins should be held at or below +8°C. We have conducted extensive research in the foodservice sector, including trials at Westminster Kingsway College, which have demonstrated that food held at a tighter and more stable temperature will stay fresh for longer periods. Food held at accurate temperature and humidity will also suff er less dehydration, thus maximising yield. Cold air spillage resulting from the frequent opening of conventional upright refrigerators
has a detrimental impact on the optimum holding temperature, which will have an eff ect on food safety and quality. By contrast, the inherent stable and accurate temperatures provided by horizontal refrigerated drawer
systems have positive implications for the safe storage of food over extended periods, reducing the amount of product which may be price discounted or thrown away due to deterioration in appearance or quality.

A+ energy rated fridges from Adande
A
dande has set new standards in refrigeration energy effi ciency with the introduction of its HCS R2 (side engine) and HCR R2 (rear engine) models, which it claims are the only two A+ rated professional fridges on the market.
Benefi tting from Adande’s patented ‘hold the cold’ insulated horizontal container technology,
the new fridges are the result of rigorous research and development. The products incorporate an energy optimised compressor and feature enhanced controller software settings to deliver improved performance. Optimisation of the units’ cooling systems provides superior temperature control, maintaining the quality of food over extended periods. The new models are designed to operate on R600a hydrocarbon refrigerant, which has a low global warming potential. By using hydrocarbon, a smaller refrigerant charge is required, reducing system pressure for less duty on the compressor and a longer life cycle. Adande claims that the new models provide a 23% energy saving, compared to its standard VCS/ VCR R600a models, in chiller mode.
