Do evaporative air coolers increase the risk of legionellosis ? And can I use it if I work in the steel industry ? Is it noisy ? <\/p>\n\n\n\n
This article gives our answers to the most frequently asked questions about evaporative cooling<\/a>.<\/p>\n\n\n\n No, quite the opposite! This question is commonly based on the incorrect assumption that evaporative coolers may cause a slight increase in humidity<\/strong>, but also increase the risk of viral, bacterial and fungal growth. All OberA evaporative coolers<\/a> are equipped with pre-filters and a UV lamp<\/strong> which treat the air<\/a>to remove particles that facilitate the movement of viruses and bacteria. <\/p>\n\n\n\n The positive effects of using evaporation are in fact well established. Not only does evaporative cooling provide clean<\/a>, fresh, filtered air, it also 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\n\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\n\n\n There are some things you can do to avoid an increase in humidity<\/strong> in your environment.<\/p>\n\n\n\n Portable coolers are usually used to cool down a specific area. This means that only a part of the total area will be cooled down. Therefore, the total humidity effect<\/strong> will usually be much lower than 2-5%<\/strong>. Keep in mind that powerful evaporative coolers actually expel warm, moist air from the building. <\/p>\n\n\n\n Legionella is a bacterium that grows in hot water systems<\/strong>. Our units are equipped with UV lamps. 100% of the water flowing on the cooling panels is treated by UV. <\/p>\n\n\n\n Moreover, legionellosis is transmitted by inhaling water aerosol contaminated<\/strong> by legionella bacteria. Our devices do not release aerosols<\/strong>. Water is vaporized or transported in the form of steam, not liquid. <\/p>\n\n\n\n The risk is therefore extremely low and is no greater than with conventional air conditioning.<\/p>\n\n\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 a speed control<\/strong> so you can reduce the speed and thus the sound<\/strong>, if necessary. The smaller the cooler, the lower the sound level. The sound level of our units is 66 dB. <\/p>\n\n\n\n Also read : Where can I use evaporative cooling ?<\/a><\/p>\n<\/blockquote>\n\n\n\n Similarly to the sound-related question 4, some people in a factory may find the airflow disturbing. In this case, you can move the unit further away or adjust the direction of the flow<\/strong>. Our air coolers have adjustable flaps, which allow you to control the direction of the air flow<\/strong>. You can also adjust the speed<\/strong> with the control panel and lower the unit’s air flow<\/strong>.<\/p>\n\n\n\n Another 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\n\n\n Installation, operating and overall ownership costs are actually quite low, so evaporative cooling is sound financially.<\/strong> Additionally, employees working in hot environments are exposed to heat stress, which can affect both their safety and productivity<\/a>. Working in a comfortable environment will improve their concentration and ability to work efficiently<\/strong>.<\/p>\n\n\n\n If your work environment is dusty or dirty, you should increase the number of times you clean and drain your cooler. We recommend emptying the water tank once a month<\/strong> when in use and cleaning it with clean water<\/strong>. <\/p>\n\n\n\n Prepping the air coolers for winter at the end of the season<\/p>\n\n\n\n The panels do not need to be changed if they are stored dry at the end of the season.<\/p>\n\n\n\n We recommend doing the following at the end of each season before storing the evaporative coolers for winter :<\/p>\n\n\n\n Please don’t hesitate to contact us if you have any other questions.

I work with steel products, so I don’t want humidity in my work environment as I want to avoid any risk of corrosion. Does this mean I can’t use evaporative cooling ? <\/h2>\n\n\n\n
