Quality Air means controlled and steady humidity levels in the air. This is the best climate to make industrial processes more efficient and to increase the overall quality of products, machineries and plants.
The presence of moisture in the air has a strong influence on the materials and can cause mold, fungus, corrosion, and hygroscopic growth of bacteria.
In production processes in any industry these problems have serious repercussions in the short to medium term on the quality of the final product, the costs of management and maintenance, and planning.
The TFT solutions for humidity control enhance and maintain high product performance in all conditions of use, increasing the efficiency of the processes and thus save money in the long run. Our machinery, specialized and advanced technology, are designed to fit every client and their specific needs.
Fields of Application
The surfaces of materials in iron and steel when in touch with air humidity get oxidized. This wouldn’t happen if the relative humidity of air stays under 50% (RH). Dehumidification, indeed, is often the best and most economic solution to protect materials from oxidation, in replace of expensive paintings. The objects that can be protected by a dehumidification systems are: bridges, electric centrals, boats (during stops), constructions in the open sea, military planes and tanks, garages and hangars, containers, boilers, turbine, sugar refineries, etc.
If the temperature of a surface is lower than the dewpoint of the air humidity, this will condensate on the surface. Employing a dehumidification system that dehumificate the air around the surface, with a dewpoint lower than the temperature of the surface, there won’t be condensation. Condensation can lead to many problems such as: corrosion, short circuit, problems on the print for plastic materials, etc. Dehumidification can be used in containers, bridges, windmill, manufacturing with cold water, beer’s industries, etc.
When air is in touch with a surface with a dewpoint lower than the temperature of the surface there won’t be ice formation; on the contrary with a condensation temperature higher than the temperature of the surface, there will be ice formation. This is a problem in the cold storage where it can cause a lower performance of the refidgerator central and continuos stops of the cycles to enable the defrost of the evaporaters. Within a dehumidification system it is ensured the absence of ice, a higher efficiency of the fridge circuit and a great energy saving.
If the air, in a productive process, is maintained with a low level of humidity, it is possible to preserve for the consumer the quality of dry food, food in powder, sweets in a solid states or others hygroscopic materials. Most of the hygroscopical materials, in their productive processes, need really low dewpoints, that can be reached only by means of chemical absorption dehumidification or combined with cooling system processes.
To dry or take off humidity from a building, whether new or damadged by flooding, the most effective system is to use an air-dehumidificator, with a particular efficiency in dehumidification such as the chemical absorption dehumidificators. Indeed, using traditional systems of drying by means of heat the only result is to move humidity from a part to another of the building, whereas if heat is combined with external ventilation will lead to high energetic costs. Within a dehumification system we will have a total expulsion of humidity from the structure and an increasing efficiency and energetic saving.
The formation of mould and fungus can be avoided if the surrounding air is maintained under the 70% of relative humidity (RH). This is important in many situations, for examples in the stocking of wood products, fabrics, etc. In these cases it is necessary to use a dehumidificator to avoid the formation of mould and fungus on products.
To increase the productive process it is necessary to maintain a relative humidity rather low during the manufacturing of products at low temperatures. Indeed, if products to be dried are sensitive to high temperatures, to maintain low levels of relative humidity at low temperatures is necessary a dehumidification system, that contributes to avoid the formation of condense and/or ice, guaranteeing better result in the productive cycle and in the cooling system, with an important energetic and money saving.
The features of eletronics components change with a high relative humidity. With a dehumidification system and air-conditioning, features do not change.
Bacteria need humidity to survive and to multiply. Often on hygroscopical materials it is indicated the level of humidity than can avoid the formation of bacteria. So, if the surrounding air is under control and maintains a low temperature and relative humidity, under 50 %, bacteria won’t found a proper environment to moltiply, without any consequences for the products.
Bad smells can be considerably reduced, if the relative humidity is under 50% (RH), with air filtration systems with a quality control of air, it can preserve a healthy and comfortable environment. With new systems of energy recovery, it is also possible to guarantee a better comfort in the environment with an important money saving. This applications are proper in places such as banks, supermarkets, hotels, big buildings put in use as offices, etc.
