Commercial pass through dishwasher

One type of commercial dishwasher is the commercial pass through dishwasher. This machine is used for dish washing and also glass washing. A pass through dishwasher just as the name suggests allows racks to be passed through. This means that as one is preparing one rack of dishes the other rack is being washed. Once that rack is done ,cleaning with it is slid out of the dishwasher through another opening and through another opening you slide in another rack for cleaning.


A commercial pass through dishwasher shares many similarities with an Underbench dishwasher. However a pass through dish washer is capable of handling more racks in an hour.

Underbench Dishwashers

Underbench dishwasher on the other hand is are basically used for dish and even glass washing when you want to save on space. This type of dishwasher is also ideal if you have a limited kitchen space because an underbench dishwasher is fitted under your counter so you do not lose any space.

 Commercial Dishwashers

The washing of glasses is a risky task appreciating that glasses are very fragile. Manual washing is a very expensive endeavor because glasses are bound to slip and break very easily. furthermore, it is a bit hard to effectively clean a glass especially those glasses that have a thin bottom. Failure to wash dishes properly will lead to bacteria breeding n such areas. This task is even more risky when doing industrial washing of glasses.


A glasswasher type of commercial dishwasher is thus specially designed for use in washing, rinsing, sanitizing and drying all kinds of drinking glasses. It performs washing of glasses of all shapes, sizes, styles and many of them at the same time. The types of glasses washable by a glasswasher are wine glasses, tumblers and dessert glasses. In addition, the glasswashers clean very fast. Glasswashers are typically used in restaurants, bars, clubs and hotels. The price of glasswasher Available in our stock ranges from 22.04 to 5750 from top brands; Adler, Fagor, Hobart, Norris, Petra and Washtech dishwasher. It is highly recommended that one have a separate commercial dishwasher for glass to avoid the transfer of oils onto glassware from food.

Selecting the size

Finally, when selecting the best commercial dishwasher for your restaurant, pub or bar, you should consider sever factors. One is capacity. Capacity is measured by the number of crockery or glasses that the machine is able to wash in an hour. This is informed by of course your customer base. Second consideration is energy efficiency. The third consideration should be if the dishwasher is stainless steel or plastic. It is recommended for you to go for stainless steel commercial dishwasher because they are more resistant to hard water and will therefore dry dishes faster.
