How we used humidification to remove dust

Dust removal in the Clean Room using a humidification system

Our installations are ideal in open spaces or even indoors. By installing our system you get 3 systems in one. By using sprayed water you are able to lower the temperature by 5-15°C, maintain the relative humidity in the space and remove dust.

Problem :

Every work environment generates dust, in some cases dust that is only 1-3 microns in size. Micro dust does not cause noticeable damage in normal manufacturing process, but in manufacturing where goods are wrapped in protective films. This dust is immediately visible when the film is applied. A problem with micro dust can result in unwanted claims or scratching of the wrapped material.

Solution:

We installed a high-pressure water pump in an area near the water mist distribution point. As there was no possibility to connect the high-pressure pump directly to the water, demineralised water is fed into our system using a domestic watermaker that draws water from a 1000l container. The pump is connected to a humidity and temperature sensor with 0.5% accuracy. This prevents excessive moisture build up that could precipitate on the products.The nylon discharge pipework is installed to the sides of the compartment, where approximately every 2 metres apart brass nozzle holders and 0.15mm nozzles are installed. The 0.15mm nozzle produces such a fine water vapour that it evaporates perfectly within 150cm, minimising the risk of product deterioration. The whole system is equipped with automatic drainage, which prevents the formation of drops when the device is switched off and on. The spray intensity is set on the pump’s intelligent control unit, where there is the possibility to set the system on time and off time, this timer acts as an automatic cycler. The higher range pumps include pressure sensors on the inlet and outlet side, a pump temperature sensor and protective elements to prevent damage to the pump.

Result:

With our system we were able to minimize dust flying around in the production area and were able to minimize our customer’s losses.By installing the SANFOG system, the customer also achieved a better working environment for their employees as the relative humidity is kept at a healthy level and the system also reduces the temperature by 5-10°C in the production area.
