Commercial Dishwashers by Design & Layout

Choosing the best commercial dishwasher layout helps staff process dish racks efficiently while maximizing available dishroom space:

• High-Temp Door-Type Dishwashers – Upright commercial dish machines from Hobart, Jackson, and 5O7O built for straight-through or corner dish table layouts in restaurants, cafeterias, and institutional kitchens

• High-Temp Undercounter Dishwashers – Space-saving 24-in. front-loading dishwashers from MoTak and Centerline by Hobart that fit beneath counters, prep areas, and bar stations

• High-Temp Glass Washers – Commercial glass washers designed to clean bar glassware, stemware, and beverage service items without relying on chemical sanitizing during the rinse cycle

• Ventless High-Temp Dishwashers – Commercial dish machines with heat-recovery technology that helps condense steam and preheat incoming water, potentially reducing or eliminating the need for a separate ventilation hood

Choosing the Best High-Temp Commercial Dishwasher

Reviewing capacity, utility, and installation requirements can help you choose a high-temperature dishwasher that fits your operation:

• Integrated Booster Heaters – High-temp commercial dishwashers require a final rinse temperature of at least 180 degrees Fahrenheit for hot-water sanitizing. If your facility's water supply cannot reach that temperature, look for a model with a built-in 40-degree or 70-degree rise booster heater

• Rack Capacity & Throughput – Match the machine to your busiest dishwashing periods. Undercounter commercial dishwashers often process 24 to 30 racks per hour, while door-type models support higher-volume restaurant and cafeteria dishrooms

• Utility & Phase Specifications – Commercial dishwashers require specific electrical setups. Verify voltage, phase, plumbing, drainage, and ventilation requirements before ordering

• Chemical & Rinse Efficiency – Because high-temp dishwashers sanitize with hot water rather than chemical sanitizers, they can help reduce chemical residue, support faster drying, and keep dinnerware and glassware ready for service

Frequently Asked Questions

What is a high-temp commercial dishwasher?

A high-temp commercial dishwasher is a restaurant dish machine that uses hot rinse water—typically at least 180 degrees Fahrenheit—to sanitize dishes, glasses, flatware, and kitchen tools.

Do high-temp dishwashers need chemicals?

High-temp dishwashers still use detergent to remove food soil, grease, and residue, but they don't rely on chemical sanitizers during the final sanitizing rinse.

Does a high-temp dishwasher need a booster heater?

Many high-temperature commercial dishwashers need a built-in or external booster heater to raise incoming water to the required sanitizing temperature. Check your building's hot water supply and the dishwasher's specifications before installation.
