The very raison d’être of a commercial warewasher is that it can clean all cooking- and tableware, and to do this, it obviously has to use detergent. However, the way detergent is dispensed does vary from manufacturer to manufacturer, so what do distributors need to know about the options on offer?
As Winterhalter UK’s marketing development manager, Paul Crowley, explains: “The wash process is made up of four components: time, chemicals, temperature and a mechanical action.”
For his brand, he detailed: “Our machines are manufactured so each of these components can be individually altered to deliver optimal results. In some cases water hardness can affect how much detergent is used, so dosages can be adjusted according to on-site conditions.”
All of Winterhalter’s undercounter range has integrated detergent dispensers. When detergent or rinse aid runs out, the machine is designed to notify the user with an audible noise and a flashing screen icon. This should also happen in other Winterhalter machines, even if they do not have integrated dispensers. Detergent is topped up using a specially-designed funnel.
Crowley advised dealers to emphasise to end users that: “Winterhalter machines’ detergent dosing can be fine-tuned to each site’s conditions. This ensures detergents are always optimally dosed to deliver the very best wash result.”
Elsewhere, Electrolux Professional has a working arrangement with one of the major players in the worldwide chemical market, which enables it to carry out the research and development on its dishwasher range using these detergents. Steve Bowler, category manager for Warewashing, revealed: “As a result, we can test our warewashers to a consistently high standard, and ensure their long term performance and detergent efficiency.
“There are many different factors that affect how much detergent a dishwasher uses, and dealers should be on the lookout for features that will reduce running costs overall. For example, the green&clean Hood Type from Electrolux has a Clear Blue filtering system that keeps the water inside the machine as clean as possible. Alongside its 2litre rinse and small wash tank, this minimises the amount of energy, water and detergent needed for the green&clean to achieve the very best results.”
