Stainless steel pass-through sinks
A pass-through sink, also known as a transit table or pass-through dishwasher table, is a tough stainless steel unit designed to connect directly to the side of an industrial pass-through dishwasher. Unlike standard kitchen sinks, the pass-through sink is just one part of a bespoke dishwashing station within a commercial stainless steel kitchen. This bridges the physical gap between where dirty dishes, placed there by the kitchen staff, are then cleaned. Fabricated from heavy-duty 1.5mm or 2.0mm gauge austenitic 304 stainless steel, these custom inlet benches provide the structural rigidity needed to withstand non-stop cycles of loaded 500mm x 500mm warewashing baskets, heavy Gastronorm pans, and soaking stockpots without flexing or buckling under extreme service pressure.
The cleaning and washing process:- to ensure a continuous flow of clean plates and dishes emerging from the dishwasher, pass-through sinks are constructed to ensure that constant, high-volume dishwashing is a highly efficient process. By aligning the inlet bench, pass-through hood machine, and clean exit tabling into an unbroken straight line or space saving corner configuration, specifiers can engineer a logical dirty-to-clean flow that eliminates cross-contamination and complies fully with UK Environmental Health and HACCP zoning standards.
To optimise pot-wash workflow, these deep basins connect neatly to professional stainless dishwasher tabling for rapid loading. Specifiers can incorporate extra-deep 300mm to 400mm bowls fitted with removable perforated stainless scrap baskets and corner overflow weir pipes, ensuring coarse food waste is intercepted before it can enter grease traps or municipal drains.
Standard dishwashing racks align perfectly with specially adjusted lips and tracks to glide easily from the sink into the dishwasher. This allows kitchen staff to push the full racks into the machine without having to lift them; they slide straight into the dishwasher. The front and rear profiles feature continuous, brake-pressed guide rails folded to match the exact hood profile of major commercial dishwasher manufacturers—such as Hobart, Winterhalter, Meiko, and Classeq—minimising manual handling risks and preventing water dripping onto the floor during rack transit.
Options include a bin chute cut out in the steel adjacent to the sink bowl where food waste can be directly scraped into an under-worktop receptacle. This reduces occurrences of grease build-up which blocks drains. Dishes and plates are then rinsed using a high pressure water nozzle and scraped before the final washing stage. Fabricators can reinforce the rear upstand with double-skinned bracing plates to support deck-mounted or wall-mounted pre-rinse spray arms without metal distortion, while adding integrated splashbacks up to 300mm high to protect adjacent wall finishes from high-pressure back-spray.
To handle this intense pre-washing environment, these units are manufactured with seamlessly integrated welded-in sinks, ensuring a completely watertight, crevice-free surface that eliminates bacterial dirt traps. Dishes and plates are then rinsed using a high-pressure water nozzle and scraped before the final washing stage. Underneath, the entire assembly can be mounted on fully TIG-welded 40mm x 40mm stainless box-section legs fitted with adjustable anti-slip flanged feet and open undershelves configured to store spare dishwashing baskets or 25-litre chemical detergent drums off the floor for easy washdowns.
