Direct addition to humidification water

Due to the higher level of relative humidity, your precious products are exposed to a dramatically higher microbiological risk since humidity provides a far better environment for the growth of mould and other microorganisms. As a food processing aid you can add L.O.G. four W5 to humidification water without having to indicate it on the packaging and without having to alter your products.


Direct addition to water-transport systems

AirSolution L.O.G. four W5 is very effectively used in water-transport systems and process water to eliminate germs in a proactive, sustainable manner and on a long-term basis. The formation of biofilms is prevented, even before anything could start to develop. This way you prevent the risk of your food getting microbiologically contaminated right from the beginning. And, from a microbiological point of view, you do not have to change process water, which enables you to save a lot of water.
