The hood type dishwasher \u2014 also sold as a pass through dishwasher \u2014 is the machine most restaurants and hotel kitchens settle on after outgrowing an undercounter unit. It sits under a condensate hood, takes standard 500\u00d7500 mm racks, and a single operator can push 40 to 60 racks through per hour. This guide explains how it works, what it costs to run, and how to compare models before requesting quotes.<\/p>\n
An operator rolls a loaded rack into the machine, pulls the hood down, and the cycle runs automatically: wash, then a hot final rinse. The hood lifts, the rack rolls out clean, and the next rack rolls in. Wash and rinse tanks sit below the deck; the condensate hood above captures the steam a 60\u201380\u00b0C wash releases.<\/p>\n
The pass through layout is the same machine from the other direction \u2014 racks enter on one side of the hood and exit on the other, passing straight through. Choose the direction that matches your dishroom flow: dirty drop-off on one wall, clean staging on the other.<\/p>\n
Undercounter machines tuck under a worktop and suit bars and cafes up to roughly 30 racks per hour. Three signals say it is time to move to a hood type machine:<\/p>\n
Above 60 racks per hour sustained, compare rack conveyor dishwashers<\/a> instead \u2014 the step after hood type.<\/p>\n A hood type machine uses roughly 2 to 3 liters of water per rack. High-temp models draw a 180\u00b0F final rinse, which requires a booster heater and usually a condensate hood for steam extraction; low-temp chemical-sanitizing models skip the booster and often the hood, trading hot water for sanitizer chemicals.<\/p>\n Compare candidates on three numbers: water per rack, tank heating power (recovery speed between racks), and connected load. Our cost guide<\/a> shows how those numbers translate into monthly running cost, and the water temperature guide<\/a> covers the sanitizing requirements behind them.<\/p>\n Most wash 40 to 60 racks per hour, depending on cycle length. A 60-second cycle with fast hood movement sustains about 60; longer cycles for heavy soil drop the number to around 40.<\/p>\n Hood type machines typically run $5,000 to $15,000 installed, moving with chamber height, tank power, and heat recovery options.

The terms describe the same hood-lift machine used in different flow directions: hood type loads front-to-back under the hood, pass through loads one side and unloads the other. Specifications and racks are identical.<\/p>\nRunning costs: water, power, and the hood<\/h2>\n
