The new AD55 passthrough dishwasher from Nelson’s just-launched Advantage Plus range has been designed with an integral condenser that captures the hot steam generated during a wash cycle and utilises it to heat incoming cold water.
This step is aimed at eliminate the need for a steam condensate hood which, as well as carrying a substantial cost, is often not a viable option. The built-in condenser constitutes a major part of the machine’s energy efficiency features, accounting for claimed significant electricity savings of up to 30%.
Other features include double skinned insulation, which should prevent heat escaping, and a shallow wash tank that uses the minimum quantities of water and energy necessary to ensure a quality wash. The machine draws 2.9litres of rinse water per cycle which is then used in the subsequent wash. The pressure-pumped rinse water is heated to 85°C, managed by a thermostop control to provide disinfection.
Using less water means that filtration becomes more critical and the AD55 is fitted with a three part filtration system that maintains water quality by trapping the smallest food particles and disposing of them with the coolest, dirtiest wash water at the end of each cycle. A lower volume of water means that less chemicals are required and the peristaltic pump dosing system for detergent and rinse-aid, which is calibrated to individual customer needs, releases the optimum amount per wash cycle.
The AD55 has five standard wash programmes and a further customisable one. The unit has two stainless steel combined wash and rinse arms with strategically angled directional jets which are designed to stream water to every part of the wash tank.
A ‘soft start’ option begins gently before gaining momentum, which is designed to prevent items from chipping, cracking or breaking. The clear electronic controls should be straightforward to use and, in the event that a problem should occur, the machine has a self-diagnostic fault system. A self-clean programme avoids the need for manual cleaning and, in the event this is overlooked, it will commence automatically after an extended period of non-use.
When the machine hasn’t been used for a while it will revert to standby mode, thus ensuring no unnecessary energy is wasted.
