Winterhalter’s new undercounter warewasher, the UC Excellence iPlus, uses a new hybrid technology that combines reverse osmosis (RO) and a water softener. This is intended to prevent blockages of the RO membrane and extend membrane life.
Warewasher reverse osmosis systems have tended to be bulky, use lots of water and stretch beyond caterers’ budgets. However, Winterhalter believes that the UC Excellence iPlus brings the advantages of reverse osmosis to tight counter areas because the system is fully integrated into the machine.
The smallest model measures 810mm (h) x 460mm (w) x 617mm (d). It can wash up to 77 racks (400mm x 400mm) per hour.
The UC Excellence iPlus is designed to remove almost 100% of water impurities. Alongside its RO system is an integral water softener. The water treatment process is fully integrated into the wash process to deliver good wash results on glassware, cutlery and dishes, without the need for extra polishing.
The appliance features a built-in pre-filter with monitoring, membrane flushing and Winterhalter’s AquaOpt system, which is said to minimise running costs with its choice of good, better and best results. This AquaOpt function should optimise water quality during extended wash break periods and can be adapted to meet specific on-site requirements, ensuring consistent washing.
Thanks to the integrated softener, the iPlus machines also feature VarioAqua. This feature allows the user to select whether to use the RO system or not. So less critical items can be washed using softened water only, which minimises running costs, while more important ones can have the full RO treatment.
Both water treatment systems are fully integrated within the warewasher, with the operating status displayed on the control panel. The machine automatically selects the appropriate treatment for certain functions – for example, RO-treated water to flush the boiler, but softened water to run the self-cleaning programme. If there is an issue with the RO, such as the membrane needs attention, the warewasher should switch to softened water only. Similarly, if the softener runs out of salt, it switches to RO only.
Compared to standard RO systems, the UC Excellence-iPlus is claimed to save at least 10% in water usage.
Winterhalter’s UC Excellence machines are said to be the only warewashers with integral RO that can be individually tailored to meet the site’s specific conditions, such as the hardness of water, water pressure, and so on. This should also save water and optimises the use of all resources – the saving is dependent on the individual site.
The UC Excellence iPlus is available through Winterhalter dealers nationwide. List prices start at £7,085 for a UC-S version.
