Passthrough Dishwashers

Passthrough Dishwashers

Commercial passthrough dishwashers provide a high-capacity warewashing solution for busy professional kitchens, restaurants, hotels, canteens and other catering environments. Also known as hood-type dishwashers, these machines are designed to handle larger volumes of crockery, cutlery and suitable kitchenware than smaller undercounter machines, helping businesses maintain a steady supply of clean items during busy service periods.

Our range of passthrough dishwashers includes commercial machines with different basket sizes, capacities and configurations, including models with drain pumps, water softeners and heat recovery systems. With the dishwasher positioned between loading and unloading areas, the passthrough design can also help create a more efficient washing workflow in kitchens where larger quantities of crockery need to be processed.

Choosing a Commercial Passthrough Dishwasher

Passthrough dishwashers are particularly suited to professional kitchens where the volume of crockery and cutlery being washed makes a compact undercounter dishwasher less practical. The hood-type design allows a rack to be loaded at one side, washed within the machine and then removed from the opposite side, helping to separate dirty and clean items within the washing area.

When choosing a commercial passthrough dishwasher, consider the number of racks that need to be processed during busy periods, the available installation space and the required electrical and plumbing connections. Basket size, wash cycle time, loading height and overall machine dimensions should all be considered when comparing different models.

Passthrough and Hood-Type Dishwashers

Commercial passthrough dishwashers are often referred to as hood-type dishwashers because the washing chamber is accessed by raising a large hood. This provides a practical loading height and allows the machine to be integrated into a dedicated washing area with suitable inlet and outlet tables.

The configuration can help create a more organised workflow by providing separate areas for dirty and clean racks. This can be particularly useful in larger kitchens where staff need to process significant quantities of crockery and kitchenware throughout the day.

Capacity, Rack Size and Washing Throughput

The capacity of a passthrough dishwasher is an important consideration when choosing equipment for a busy commercial kitchen. Machines are available with different rack sizes and wash cycle times, allowing businesses to select equipment according to the volume of crockery and other suitable items that need to be cleaned.

Consider the number of racks that may need to be processed during the busiest service periods rather than relying solely on average daily usage. A machine with an appropriate rack capacity and cycle time can help maintain a consistent supply of clean crockery, while the internal clearance should also be checked to ensure that plates, trays and other items can be accommodated safely.

Water Softeners, Drain Pumps and Heat Recovery

Commercial passthrough dishwashers are available with different configurations to suit varying installation and operating requirements. Models with integrated or optional water softeners can be useful where water hardness is a consideration, while drain pumps can provide additional flexibility where the waste connection cannot rely solely on gravity drainage.

Some higher-specification machines are also available with heat recovery systems designed to make use of heat generated during the washing process. The exact benefits and requirements vary between models, so the manufacturer's specifications should always be checked when comparing water treatment, drainage and heat recovery options.

Passthrough Dishwashers for Busy Commercial Kitchens

A commercial passthrough dishwasher can be particularly suitable for restaurants, hotels, catering operations, schools, canteens and other professional kitchens where large quantities of crockery and cutlery need to be cleaned throughout the day. The combination of commercial washing capacity and a dedicated loading and unloading arrangement can help reduce bottlenecks during busy service periods.

The available space around the machine is also important. Passthrough dishwashers are generally installed as part of a wider washing area, so sufficient room should be allowed for loading and unloading racks, opening the hood and safely moving staff and equipment around the machine.

Installing a Commercial Passthrough Dishwasher

Before purchasing a passthrough dishwasher, measure the available installation area and check both the closed and open height of the machine. The hood can substantially increase the overall height when raised, so sufficient clearance must be available above the appliance for normal operation.

Water supply, drainage, electrical requirements and any ventilation or extraction requirements should also be considered before installation. The delivery route into the building and kitchen should be checked carefully, as commercial passthrough dishwashers can be large and heavy pieces of equipment.

Passthrough Dishwashers vs Undercounter Dishwashers

Undercounter dishwashers can provide a compact solution for smaller kitchens and businesses with moderate washing requirements, while passthrough dishwashers are generally better suited to environments where higher washing throughput and a dedicated loading and unloading workflow are required.

If space is limited or your business does not require the capacity of a hood-type machine, see our Undercounter Dishwashers. For very high-volume operations requiring continuous rack processing, our Rack Conveyor Dishwashers provide another commercial warewashing option.

Passthrough Dishwasher Accessories

A passthrough dishwasher can form part of a complete commercial washing area incorporating suitable inlet and outlet tables, dishwasher baskets and other compatible accessories. The correct arrangement can help provide a more efficient flow of dirty and clean items through the washing process.

When planning a passthrough installation, make sure that any tables, baskets and accessories are compatible with the selected dishwasher and fit the available space. The manufacturer's installation guidance should be followed when positioning the machine and associated equipment.
