Industrial Glasswasher And Dishwasher – Which One Do You Need For Your Commercial Kitchen?

Industrial glasswasher and dishwashers, in Hospitality they differ by the type of use (washing of glasses or crockery), although they are really the same machine.

In hotel jargon, small machines that have a square or round basket between 14″-16″ centimeters are called a glass washer, reserving those with a 20″× 20″ larger basket for dishwashers.

Normally all the restaurants and bars (with kitchen) usually have two industrial dishwashers, one dedicated to the washing of glasses and another for tableware (crockery).

The reason is that industrial dishwashers have a reservoir of washing water that when washing dishes with food waste dilutes the fat and is mixed with water.

All industrial dishwashers (to save water and be able to wash quickly) only renew a few liters for each wash if we wash glass (after having washed dishes) with that water with grease diluted, it sticks to the glass and dims and the grease will be fixed to the glass in the rinse process when the machine vaporizes the rinse aid.

What is a dishwasher?

A dishwasher is an electro-mechanical appliance for cleaning food scraps from dishes, cutlery, glassware and kitchen utensils. It can be found in restaurants and also in private homes.

I call the small industrial dishwasher with a 14″× 14″ or 16″× 16″ basket dishwasher that has only one wash arm at the bottom.

This does not mean that a glasswasher cannot wash dishes, 16″× 16″ glass washers usually have a mixed-use in small bars that do not have space for two machines (Cups and Dishwashers); In this case, it is recommended that the dishwasher has two upper and one lower wash arms for better performance.

A glasswasher is used to wash glassware and small plates, usually coffee cups and plates. The height of the door is important in the choice since it will determine the type of cups that fit in it.

It is recommended that you buy a glasswasher with a door height greater than 10″ to avoid problems with tall glasses (such as wine, champagne, combined, etc.)

What is an industrial dishwasher?

This is a series of compact professional electromechanical dishwashers with the most simple and user-friendly on the market for washing all types of dishes, cutlery, cups, glasses, etc. with a 16″× 16″ or  20″× 20″ basket, under counters, hood, tunnel or continuous belt.

The dishwashers differ from each other in the power of the washing pump (the higher the pressure the better the wash and the cycle shorter); This fact will really condition the number of dishes/hour that can range from 400 to 940 plates/hour in a dishwasher or up to 3600 plates per hour in a continuous tunnel dishwasher.

What is the difference between an industrial and a domestic dishwasher?

Speed to begin with. It is impossible to achieve 2-minute washes without recirculating the wash water and this is what professional dishwashers do.

The industrial dishwasher is very practical and comfortable, as it saves a lot of time and effort for the kitchen or cleaning staff and the great secret is the speed, as it can wash in 2 or 3 minutes thanks to the fact that the water used for washing (not the water used for rinsing) is used from one wash to the next and so we have hot water and soap immediately.

The water accumulates at the bottom of the tank and is driven by the wash pump over and over again. After the washing cycle, the rinsing cycle begins and this is done with new, clean water.

This new water falls into the vat, thus renewing the other stagnant water and the surplus goes into the overflow.

In addition, industrial dishwashers for the hotel and catering industry provide a professional finish, leaving dishes and glasses completely clean, with no residue, and very shiny.

As if this were not enough, it also guarantees the correct disinfection of all the dishes, glasses and other items that may have been washed.

Dishwasher Measures and Features:

Door Height and Useful Washing Height: This feature is very important in a glasswasher since a large portion of 14″ × 14″ or 16″ × 16″ basket washers have a wash height of 22 to 10″; Currently, with the glasses of beer or wine, heights of 8″ or 10″ cm are handled.

So when buying a glasswasher we have to make sure that it is a «H» model with a minimum wash washing height of 10″ to 11″ centimeters.

Cup washer Basket 14″ x 14″: They are normally used in small bars (up to 645 p2), their advantage is the small size of them, but the basket limits the number of glasses or cups per wash, the most common measures of the glasswasher are 18″ x 20″ x 24″

16″ x 16″ Basket cup washers: They are normally used in small bars (up to 1000 p2), or as a complement to bar washing, it has a suitable size for the washing of glasses and cups in a bar.

It is the most commonly used cup washer in hospitality, 16″ x 16″ cup washers usually have mixed-use in small bars that do not have space for two machines (Cup washer and Dishwasher).

The most common measures of glasswashers 19″ x 20″ x 25″

Dishwasher Basket 20″ x 20″: They are normally used in small and medium bars/restaurants (up to 1290 p2), have a suitable size to place under the sink or one of the work tables taking up very little space.


Hood Dishwasher (20″ x 20″ Basket): They are normally used in medium and large bars and restaurants (more than 1290 p2), need a minimum space of 24″ cm, usually placed next to a sink that serves as a table entrance and optionally an exit table for the collection of dishes.

Tunnel or Tape Dishwasher: They are normally used in large restaurants dedicated to banquets and events or in kitchens of residences, hotels, and communities since their production is usually measured by thousands of dishes/hour.


Whenever you have only one machine, the process is first glasses and then dishes, once the washing is finished, you must empty the water from the tank, fill it again and do a couple of empty washes, empty the machine again and it would be ready for the next day.

A fundamental difference with domestic dishwashers is the washing cycle, in a domestic one we talk about an hour of washing.

In an industrial dishwasher the washing cycle is two to three minutes (at 50-55º C, in the last thirty seconds ( approximately) what is called sanitary washing or sanitation is produced by vaporizing water (with rinse aid) at 85º C, which serves to allow the dishes to dry quickly and sanitize it.
