OberA air fresheners<\/a> are equipped with pre-filters and a UV lamp<\/strong>, which treat the air to eliminate particles that encourage the movement of viruses and bacteria. <\/p>\n\nThe positive effects of using evaporation are in fact well established. In addition to providing clean, fresh, filtered air, evaporative cooling consumes significantly less energy<\/strong> and is easier to maintain<\/strong>. It does not require the use of harmful CFC gases – unlike many air conditioners.<\/p>\n\nI work with steel products, so I don’t want any humidity in my working environment because I want to avoid any risk of corrosion. Does this mean that evaporative cooling cannot be used?<\/h2>\n\n
Do our coolers evaporate water ? No The water in the cooler is in the form of vapor, not liquid (micro-droplets). Humidity will increase between 2% and 5%, depending on the environment<\/strong>.<\/p>\n\nThere are some things you can do to avoid an increase in humidity<\/strong> in your environment.<\/p>\n\n\n- Increase ventilation<\/strong>(open doors and windows). More ventilation means less humidity. The more ventilation there is, the less humidity will increase <\/li>\n\n\n\n
- Monitor the temperature and humidity<\/strong>to keep it at the right level at all times. Our evaporative coolers feature a built-in control panel<\/strong> to set the level. <\/li>\n<\/ul>\n\n
We often talk about spot cooling with portable coolers. This means that of a total surface area, only a portion will be cooled. As a result, the total humidity effect<\/strong> will generally be much lower than 2-5%<\/strong>. Also, bear in mind that powerful evaporative coolers actually expel warm, humid air from the building. <\/p>\n\nDoes evaporative cooling increase the risk of Legionella because it uses water ?<\/h2>\n\n
Legionella is a bacterium that thrives in hot water systems<\/strong>. Our units are equipped with UV lamps. 100% of the water running over the cooling panels is treated by UV. <\/p>\n\nWhat’s more, Legionnaires’ disease is transmitted by inhalation of an aerosol of water contaminated<\/strong> with Legionella bacteria. However, our units do not spray aerosols<\/strong>. Water is vaporized or transported in vapour form, not in liquid form. <\/p>\n\nThe risk is therefore extremely low and is no greater than with conventional air conditioning.<\/p>\n\n
Can I reduce the noise level of an evaporative air cooler ?<\/h2>\n\n
The noise levels of our units are generally below the existing noise level<\/strong>in our main markets (industry, logistics, production) Moreover, the importance of the cooling effect far exceeds that of the sound reduction. Our coolers are equipped with speed control<\/strong> so you can reduce the speed and therefore the sound<\/strong>, if necessary. The smaller the cooler, the lower the sound level. The noise level of our units is 66 dB. <\/p>\n\nWhat can I do to adjust the airflow ?<\/h2>\n\n
Similar to question 4 on sound, in a factory hall, some people may find the airflow disturbing. In this case, it is possible tomove the unit away or adjust the direction of flow<\/strong>. Our coolers are equipped with adjustment vanes, which allow you to control the direction of the airflow<\/strong>. You can also adjust the speed<\/strong> with the control panel and lower the unit’s air flow<\/strong>.<\/p>\n\nAnother solution is to place the cooler at a higher location<\/strong> to avoid directing the air towards people (the cool air always moves downwards, so this solution also guarantees proper cooling).<\/p>\n\nWhy bother spending money on comfort – it’s cheaper to do without, right ?<\/h2>\n\n
Installation, operating and overall ownership costs are actually quite limited, so in terms of use, evaporative cooling is a financially sound solution<\/strong>. What’s more, employees who have to work in hot environments are exposed to heat stress, which will affect both safety and productivity. Working in a comfortable environment will improve their concentration and ability to work efficiently<\/strong>.<\/p>\n\nHow do I clean my air cooler and store it at the end of the hot season ?<\/h2>\n\n
If the working environment is dusty or dirty, the frequency of cleaning and draining must be increased. We recommend emptying the water tank once a month<\/strong> during periods of use, and cleaning with clear water<\/strong>. <\/p>\n\nPrepping the air coolers for winter at the end of the season<\/p>\n\n
The panels do not need to be changed if they are stored dry at the end of the season.<\/p>\n\n
We recommend doing the following at the end of each season before storing the evaporative coolers for winter :<\/p>\n\n
\n- Drain the units<\/strong><\/li>\n\n\n\n
- Rinse them with clean water<\/strong>.<\/li>\n\n\n\n
- Run the appliances with clean water<\/strong> and add white vinegar if needed.<\/li>\n\n\n\n
- Drain them completely<\/strong><\/li>\n\n\n\n
- Run them for at least 6 hours without water<\/strong> to dry the panels and the unit<\/li>\n<\/ul>\n\n
