Spotlight on the D500DUO & G400DUO

25th November 2021

Every warewashing manufacturer will have lots of models to choose from, with so much choice it’s sometimes difficult to know where to start.

Each model in the range is there as we know it meets a need, no two operators are the same so choice is important. Within any range, some models will be more popular than others, those core machines that get the job done for lots of different customers.

This article spotlights two of our most popular machines that are keeping plates and glasses clean across the UK and beyond, the D500 DUO dishwasher and the G400 DUO glasswasher.

Understanding the benefits and specifications of these two machines is a great way to start your selection process for a new machine. From here you will have the basic understanding to navigate around the range, if you’re washing in high volumes you may want to look at a pass through or if space is an issue, you might consider a smaller machine. We know budget will always be a factor and have a range of units at different price points.

Simple to use and robust in its construction, the D500 DUO features intuitive colour coded lighting and an LCD display making the machine really easy to use. Once switched on you can start a wash with just one button push and monitor wash tank and rinse boiler temperatures via the display.

The machine features a built-in drain pump, rinse booster pump and chemical dispenser immediately addressing any on site challenges around space, water pressure and drain height.

There’s also an option to add an integral water softener, an essential addition if you’re in a hard water area.

All DUO models have Type AB WRAS certification ensuring compliance with water authority regulations and double skinned sides and door to allow for quieter operation and reduced heat loss.
