Winterhalter PT-XL Pass Through Dishwasher

The Winterhalter PT-XL is a pass-through rack dishwasher designed for high-volume commercial kitchens where throughput, reliability, and running costs all matter. Unlike smaller undercounter units, pass-through machines are loaded and unloaded from opposite sides, which suits kitchens with a defined dirty-to-clean workflow — typically larger restaurants, hotels, staff restaurants, and contract catering operations where crockery, glassware, and cookware move continuously through service.

In operation, the PT-XL is built to handle sustained demand across a full service period. The VarioPower system adjusts wash cycles and chemical dosing according to what is actually being washed, which reduces unnecessary consumption during lighter loads without compromising results when the machine is under pressure. The flexible energy management system also reduces heating time significantly, which matters when the machine is cycling repeatedly across a long shift.

From an efficiency standpoint, several features work together to keep running costs in check:

• Waste water heat exchanger reduces energy costs by recovering heat from outgoing water
• Low rinse water consumption per cycle helps manage water and chemical spend over a full day
• Quadruple filtration keeps wash water cleaner for longer, reducing the need for frequent tank changes
• Tank water exchange programme supports hygiene standards between service periods
• Double-skinned construction reduces heat loss and helps manage ambient kitchen temperature

The smart touch display gives operators clear visibility of machine status and flags errors before they affect service. The Connected Wash feature allows remote monitoring and provides usage recommendations — useful for operators managing multiple sites or looking to benchmark performance against consumption targets. Built-in self-cleaning simplifies end-of-day maintenance and reduces the burden on kitchen staff.

Installation requires adequate space for a pass-through configuration with clear access on both the dirty and clean sides — this is not a machine that can be squeezed into a tight corner. Water supply, drainage, and electrical connections will need to meet the machine's requirements, and the kitchen layout should support a logical flow from dirty to clean without crossing. This model is well suited to mid-to-large kitchens with consistent covers; smaller or lower-volume operations may find a hood-type or undercounter machine a more proportionate choice, while very high-volume sites with continuous service demands may benefit from looking at higher-capacity alternatives in the range.

If you are unsure whether the PT-XL is correctly sized for your service volume or kitchen layout, our team is happy to work through the details with you before you commit.
