The Profit Laundry® process

The ozone generation system requires a supply of oxygen with very specific characteristics. Using atmospheric air, an inner system of compression and treatment is installed.

The first step consists of compressing the required air flow until the pressure conditions needed by the oxygen concentrator are reached. This first stage is carried out using an oil-free compressor integrated inside the the ozone generator.

Then, the compressed air is led towards the oxygen concentrator, which separates the different components of the air (generally composed of 80% nitrogen and 20% oxygen). The compressed air flow crosses layers of zeolite grains, which are able to selectively absorb the nitrogen of the compressed air, thus obtaining oxygen only at the outlet of the layers.

The resulting oxygen at the concentrator’s outlet crosses the ozone generation cell, and following a series of silent discharges, it is transformed into ozone.

The ozone injector placed at the generator’s outlet creates enough suction for the ozonizer to be able to draw in all the ozonated gas produced and to make an efficient mixture with the water to be treated.

The resulting mixture of ozone/water is introduced into the contact chamber, which is carefully designed to guarantee a long enough contact time for total disinfection to take place.

The residual ozone is then extracted from the contact chamber through a degassing valve, and is eliminated by an ozone destructor so that the air emitted into the atmosphere is completely innocuous.

The ozonated water in the contact chamber is loaded into the washing machines via the main water distribution network.

The system comes complete with a control system to regulate the ozone concentration in the water that goes into the washing machines. This device is plugged into the ozone generator to monitor constant concentration, thus optimizing the disinfection process.

A system that detects the amount of ozone in the atmosphere can be also be incorporated upon request if the client wishes to measure air ozone levels.
