Two patents for a perfect washing
GR-System is completely designed and built in Italy, using high quality components and cutting-edge technology: the machine is built in AISI 304 stainless steel, the tank is thermally insulated to ensure constant temperature maintenance and reduce consumption, and the thermos-hydraulic circuits are in separate compartments to simplify maintenance operations.
Differently from other utensil washers, GR-System is the only one able to wash any utensil or removable component in a kitchen using the same water and the same detergent for a month, without any drop in performance and results.
During the washing phase the tools are completely immersed in the solution which reaches every interstice, removing dirt and descaling the entire surface of the object. In this way it is also possible to wash the hood filters, racks, the baskets of the fryers and everything that can’t usually washed with traditional machines.

GR-Detergent is a product designed specifically to maximize the washing efficiency of the GR-System, preventing cross-contamination and disinfecting the treated tools.
Its special mixture ensures constant and unaltered effectiveness for a period of one month on all types of materials, including aluminum and polyethylene objects.
The formula:
- is not caustic;
- doesn’t release residues dangerous for food use;
- doesn’t oxidize aluminum;
- respects the environment and human health.

The difficulties of washing and managing large objects, such as pots, trays and hood filters, are also due to the size and weight of these utensils.
For this reason GR-System use a manual hooking system of the basket tray, specially designed to make the loading and unloading phase easier for the operator.
But we have done more: to simplify these operations, especially in the larger models, we have patented an automatic lifting system that allows, by pressing a single button, to raise and lower the tray with objects inside.


Why choose GR-System
Aluminum is a very common material in the industrial kitchens because of its high thermal conductivity and low weight: furthermore, being easily shaped, it is also largely used in bakeries and pastry shops to create molds for desserts.
However, aluminum requires special care during washing since it oxidizes very easily.
GR-System is the only technology in the world that can clean aluminum cookware, without oxidizing it, without blackening it and without leaving any patinas, bringing the pot to the original.

Cleaning the grids is a tiring and long process: even if they are soaked and manually rubbed they never come back to the original state. Immersion washing with the GR-System avoids all this kind of manual work.
The difficulties of cleaning the hood filters can cause a deposit of grease which can fall down, create bad smells, malfunctions or even fires. Washing with the GR-System you can avoid all this.

GR-System is practical because it allows to wash what you need anytime you need it, 24 hours a day, without interruptions. The washing cycle lasts few minutes and, to immediately have the objects ready to be used, it is sufficient to rinse them with running water.
GR-System is effective because it degreases deeply and removes even the heaviest and oldest charred incrustations by sanitizing all materials, including teflon made cutting boards. It is no longer necessary to rub manually and use sponges or scouring pads, which are unhygienic and a dangerous source of cross-contamination.


Grease and charred incrustations, potentially dangerous for the health of customers, are inevitable consequences of working in the kitchen, but the sanitization of all utensils and accessories is expensive and involves a considerable waste of manpower for non-qualifying tasks.
Thanks to GR-System the crew will no longer have to rub for hours using toxic and harmful chemicals. Less effort and less non-qualifying work contribute to a better efficiency and a more relaxing working atmosphere.
Washing continuously kitchen utensils involves significant costs for water and detergent. Thanks to the special combination of detergent and washing system adopted, the GR-System solution is able to guarantee unaltered performance for a month, without having to add water or detergent in this period of time. This involves a significant economic savings.
Choose GR-SYSTEM to save money
- Save water. The GR-System tank is filled once per each washing cycle (on average 30 days) and the solution maintains the same effectiveness from the first to the last day.
- Save space. With GR-System it won’t be any longer necessary to soak tools in special tanks.
- Save on staff costs. No staff employed in manual washing and rubbing of incrustations from pots and pans.
- Save energy. Thanks to the high insulation and the heating technology used, the water is kept at a constant temperature with very low energy consumption.
- Reduce the use of chemicals. Thanks to GR-System you can avoid the use of all the dangerous chemicals normally used, such as caustic soda.
- Save time. For extraordinary cleaning it is possible to prolonge the washing cycle during the night, with a considerable saving of time during working hours.
