Flight type and rack conveyor dishwashers both support high-volume warewashing, but they solve different problems. In busy commercial kitchens, conveyor machines move racks through a tunnel; flight type systems move tableware continuously for the highest tray and plate volumes. This guide compares both warewashing systems so foodservice industries of every size can pick the right ware washing setup.
How the two systems work
A rack conveyor dishwasher — different from stationary rack machines that wash one rack at a time in a fixed tank — carries loaded racks through wash and rinse sections. It is a strong fit for restaurants, hotels, cafeterias, quick service restaurants, and institutions that need higher throughput than a hood type machine while still handling items in racks.
A flight type dishwasher uses a continuous belt or flight chain. Operators place plates, trays, bowls, or cutlery carriers directly onto the system, making it better for meal peaks where thousands of items return in a short window.
Capacity, labor, and footprint tradeoffs
Conveyor dishwashers usually require less floor length and are easier to fit into existing dishrooms. They are often selected when the kitchen still uses rack-based sorting, keeps extra racks on hand for peaks, and has a steady but manageable rack flow.
Flight type systems need more planning, longer layouts, and stronger utility coordination, but they can reduce handling steps and stabilize labor in central kitchens, universities, hotels, and large canteens.
Utility and installation checks before you buy
A conveyor dishwashing machine must come with the right utilities and site preparation, or even the best spec sheet will not deliver. Before signing, confirm power supply, water hardness treatment, drainage height, ventilation over the tank, and the floor space needed for loading and unloading zones.
On site, ask the supplier to walk you through the nameplate and controls. The data plate that explains cycle time, tank temperatures, and rinse pressure tells you what the machine actually does; pair it with the manual’s hand washing instructions so staff pre-scrape and rack items correctly. A quick demo with your own trays and pans reveals more than any brochure.
Warewashing professional equipment market outlook
The global warewashing professional equipment market keeps expanding as foodservice operators replace hand washing with automated warewashing systems. Market growth is driven by labor shortages, stricter hygiene rules, and rising sanitation standards across restaurants, hotels, and institutional catering.
The market is expected to grow at a CAGR in the mid-single digits through the early 2030s, and the North America warewashing professional equipment market outlook highlights replacement demand and energy-efficient upgrades as key purchasing drivers.
Product type segments split the market by machine category — undercounter, hood type, rack conveyor, and flight type — and by end user. Market share remains concentrated among key players such as Hobart, MEIKO, Winterhalter, and Electrolux Professional, while regional manufacturers compete on price, customization, and lead time. For buyers, this competition works in your favor: quote two or three vendors before deciding.
2027 update: what Oberon’s current flight type lineup looks like
Since this comparison was first published, Oberon’s flight type range has grown into three distinct tiers — useful reference points when you size either system:
- Omni Clean Series — fully automated flight type line with automatic scrapping and ultrasonic pre-cleaning, rated 3,000–10,000 plates per hour (19–24 kW) for the largest institutional sites.
- Omni Compact Series — flight type throughput (2,000 plates per hour) in a shortened footprint, at 200 L/h water consumption, for sites that cannot fit a full-length tunnel.
- SonicFlow — a hood-type machine with built-in ultrasonic pre-wash: the middle path when 70 racks/hour is enough and a full flight line is not.
If rack handling still fits your dishroom, a flight type dishwasher from the same range shares components with these lines — which simplifies spare parts and service planning across sites.
How to choose between them
Choose rack conveyor when racks per hour, available space, and staffing match a tunnel machine. Choose flight type when the bottleneck is continuous tableware return, tray flow, or the labor required to load and move racks.
Oberon can compare both ware washing options using your peak return window, item mix, floor plan, loading direction, rinse demand, drying expectations, and expansion plan.

Frequently asked questions
Is a flight type dishwasher better than a conveyor dishwasher?
Not always. Flight type systems are better for continuous high-volume tray and plate flow, while rack conveyor ware washing systems are often better for rack-based operations with less floor length.
Which option uses less labor?
Flight type systems cut loading and handling steps, so they often need fewer staff per tray at very high volumes. Rack conveyor lines keep rack handling simple and can run with fewer skilled operators at moderate volumes.
How big is the warewashing professional equipment market?
Analysts track the global warewashing professional equipment market in the multi-billion-dollar range with steady mid-single-digit growth, led by North America, Europe, and Asia-Pacific. Exact figures vary by report scope, so use them for direction rather than planning precision.
