Upright Dishwashers

Capacity varies by model, but commercial door-type dishwashers commonly handle 30 to 60 or more racks per hour. Some higher-capacity models can process substantially more, so check the manufacturer's rated throughput when comparing models

Yes. Upright dishwashers are well suited for restaurants, hotels, cafeterias, catering operations, schools, and other foodservice facilities that need more throughput than a typical undercounter dishwasher can provide.

High-temperature models sanitize using hot water, while low-temperature models use chemical sanitizers during the rinse cycle. High-temperature machines generally require suitable hot-water supply and may use a booster heater, while low-temperature machines require the appropriate chemical-sanitizing system. 

Determine the number of dishes and racks your kitchen needs to process during its busiest periods. A useful approach is to estimate peak dishes per hour, divide by approximately 20 dishes per rack, and allow additional capacity for peak demand.

Many door-type commercial dishwashers are designed around standard 20 inch x 20 inch dish racks, although rack configurations and machine specifications can vary. Always verify the rack dimensions and chamber clearance for the model you are considering. 

Requirements vary by model but may include electrical power, water supply, drainage, and ventilation. High-temperature models may also require a booster heater or appropriate incoming hot-water temperature. Check the manufacturer's installation specifications before purchase. 

Some models are specifically designed for corner installation, while others are intended for straight-through layouts. If your dishwashing area has an L-shaped configuration, look for a corner-convertible model and verify its installation requirements. 

Some upright or door-type models have tall chambers and configurations suitable for larger cookware, mixing bowls, sheet pans, and utensils. However, not every model is designed for oversized items, so check the chamber clearance, rack configuration, and manufacturer's intended applications.

Regular maintenance should include removing food debris, cleaning filters and wash components, inspecting spray arms and door gaskets, checking detergent and rinse-aid systems, and following the manufacturer's deliming and cleaning schedule. Proper daily cleaning helps maintain washing performance and equipment life.
