DehuTech Industrial Dehumidifiers
Dehumidifiers are frequently used in various sectors, including the pharmaceutical industry, food industry, warehouses, clean rooms, chemical industry, power plants, shipyards, ships, automotive industry, military, battery industry, glass industry, construction industry, water pump stations, drying and coating processes, electronics industry, living spaces, and various HVAC systems.
At the pharmaceutical industry where hygroscopic raw material content is intense, on the fabrication of a lot of products, especially tablet, dragee, capsule, dry powder suspension, %20-40 RH and 20-25° C production conditions should exactly be provided.
The use of industrial dehumidification systems is inevitable for the constant supply of low tolerance range (+/- %2 RH, +/-1°C) at hygienic manifacturing environment for the whole year. The stationary state of basis weight of product in the whole manifacturing process and the removal of negativity related to this can be possible with the usage of correctly-constructed dehumidification system.
Packaging and storing areas are two of the places where sterilization is extremely important, as is in production areas and the regular humidity control is essential for the prevention of microorganic structuring.
In most of the pharmaceutical industry applications, the simultaneous demand of humidity and heat combination with the use of fresh air, features the use of integrated dehumidification systems.
Food industry is one of the fields in which dehumidification sytstems are mostly been used in recent years. For the food industry where quite wide range conditions like %15-50 RH and 0-28°C may be necessary, the custom designed tools by Dehutech AB, provides the food producers the maximum quality and productivity with the most economical conditions.
Dehutech AB dehumidifiers provides advantages to the users in lots of issues like safe working conditions, fast and quality production, longer shelf-life, saving on energy costs and particularly provision of hygienic production fields.
Packaging processes (gum, candy, chocolate bar) cooling tunnels, cool/cold chambers, maturation and settling chambers, pneumatics conveyors, silos, spray towers, storing fields, cutting departments and drying processes are some of the areas of usage.
In food industry, packaging process is mostly applied for gum, candy and chocolate. A quality packaging reveals a uniform and smooth mold on the surface of the product. In the environments where no humidity control is made, it is a common problem that the products stick together.
For a packaging process to be successful; the air volume, heat and humidity relations should be well-built. Based on the type of the product, the value range %25-45 RH and 19- 24° C is needed.
For the true dehumidification configuration, it is essential to take the system design in the packaging pots as a whole. SKY Enerji helps its clients in the choice of project designing, capacity and system, with its experienced gained in many years.
In the food industry, product drying process is sometimes applied by natural methods and some other times by special equipments.
Dehydration of the food products requires great attention. The point that makes this operation important is the need to evaluate more than one parameters together at the same time. The factors like taste, flavor, aroma, shelf life etc. bring about the need for a different specific humidity level for almost every product.
Product drying with industrial dehumidifiers provides a range of advantages.
Saving on energy and time is possible with the help of dehumidifiers with desiccant rotor technology especially for the products that need to be dried at low temperature, so a homogeneous and a well-quality dehydration is enabled.
For an effective and high-standart dehydration, the factors like ventilation type of the dry air, product-air contact surface structure etc. should be defined accurately as much as the choice of the right device capacity. SKY Enerji and Dehutech AB brings the most efficient and economic solutions on these topics to their customers with their experience of many years.
Settling chambers are used for some kinds of products in order for fermantation, aroma additive, taste settlement and product maturation. In these areas where humidity and temperature balance is extremely important, from time to time humidification is needed but in some other times dehumidification can be necessary in reverse.
Dehumidifiers are frequently used for prevention of fungi and mould formation and for the supply of hygienic conservation in the stores where pre-shipment products are kept. The value range % 45-55 Rh, 18-24° C is preffered among the ambient conditions varying according to the product. The ideal storage conditions are provided through self-contained dehumidifiers, integrated dehumidifiers or modular dehumidification systems that enables the centralized control of temperature and humidity, based on the current conditions of the store and some other parameters.
In the slaughterhouses the floor and cutting tables’ surfaces should be washed regularly due to hygienic causes. As a consequence of washing process, the humidity levels rise dramatically and the risk of fungi formations increase. With the classical method, ventilation, this risk can not be removed.
The solution for this hardship becomes possible with the immediate removal of the humid from the environment. The dehumidifiers working constantly or at the automatic mood depending on the humidity charge to be, will reduce the humidity level and help the surfaces remain dry. This way, the hygienic conditions in accord with the food standarts can continuously be obtained.
In the slaughterhouses, in which humid control is applied, working environment without the risk of sliding with minimized occuppational accidents for personnel is created besides with healthy and continuous production.
The humidity problem frequently seen at the storage areas reveals itself as corrosion at metal products, mass increase at hygroscopic materials, product spoilage and quality problems.
The humidity level under %50 RH for metal materials provides a complete removal of corrosive effects in the long run. Optional on the temperature, systems that are working with on/off principal are generally preferred with the modular dehumidificaton systems developed by Dehutech AB for more humidity-sensitive materials, a possible risk of humidity transfer is put away.
Dehutech AB dehumidifiers are widely used to remove condensation problems observed in portable storing areas built for various purposes in the recent years.
Gas and steam turbines are the most important equipments of electricity power plants. Short and long term pauses are given to the turbines at different times especially during maintenance. In the meantime, fixed and mobile blades, as the primer equipments of turbines should be well-preserved. The reason for this is that the blades, having quite responsive surface profile, are extremely sensitive towards corrosive effects.
Dry air given under %45 RH, as a semi-open system or under positive preassure, is the most effective and economic method for the prevention corrosion formation. While it depends on the turbine package, Dehutech small-scale dehumidifiers provide %100 protection for the turbines.
It is significant to control enclosed spaces, where there are low and mid voltage equipments, particularly power plants and switching stations, with an appropriate humidity level, in terms of healthy operational conditions.
A quality painting and sanding in the shipyards, yachts and boat ateliers is the first step on the reduction of negativity that may be caused by salty sea water in the long term.
In the case of suitable humidity and temperature setting, painting and sanding processes can be done of good quality, in a very short time. Dehumidification systems which provide a uniform protection on the surfaces that has been operated on by corrosive setting features removal, supply a great advantage to the users.
Dehutech dehumidifiers produced for this purpose serve the best solution to its customers with its high-preassured fan units and its design allows mobilisation.
With the advantage of adjustable humidity capacity and variable flow dry air system, production can be made under flexible circumstances.
Another area that dehumidifiers are widely used in navigation sector is chemical tanks.
For these chemical tanks to load goods again after the unloading, the cargo tanks need to be washed and dried. Doing this process quickly acutely contributes to reducing the horbour lodging time which has an important role in the total portage costs.
The removal of the water left in the bottom of the tanks by evaporation after the washing can be possible by circulating the dryer air with a quite low relative humidity in an effective way and with enough debit.
In the tanks en route, the use of dehumidifier systems are necessary to remove the negative effect of condensation ocurring based on the temperature of the sea water in the cargo tanks on humidity-sensitive products
The devices with various reactivation options developed by Dehutech for this purpose is served to customers’ needs as self-contained or heater battery and with high preassure integrated to the fan.
The biggest problem about the long-term preservation of relics, valuable documents etc. is humidity. High humidity level creates a suitable environment not only for inorganic but also for organic molecule formation. The fungi, mould and forms like this which come up eventually causes irremediable destruction.
In order to overcome this problem, humidity level should be taken under control by stabilizing the value between %45-55 RH. It is probable to make a really economic protection by a dehumidifier unit integrated to a current air conditioning plant or a self-contained device.
A significant number of military supplies have high costs due to the advance technology they feature. Especially with each passing day more common useage of delicate electronical equipment causes an increase on the costs of defense.
On the other hand, constantly changing cyclic patern creates the need to hold the military materials ready. Therefore the preservation and maintenance should be applied with great care.
An important part of the problems that military supplies face in time is material-based. The equipments which cost millions of dollars become out of order because of the high humidity level causing corrosion on the metal surfaces and oxidation on electronic circuits.
There is even a higher risk with the materials belonging to air and naval forces.
The most effective way tto avoid all the negativity about this in both short and long term is the preservation done by dry air. All kinds of fragile equipment particularly engine, turbine and electronic components, could be kept under high protection with low cost by dry air under %50 RH, via fixed or portable dehumidifiers. By this way, maintenance costs could be significantly economised.
For ammunition and arsenals Dehutech AB dehumidifiers are widely used as well as the preservation of outfits and equipments, and alternating system applications become feasible by considering the physical conditions of arsenals.
There occurs condensation in the enclosed areas where there is water or watersprings, in the majority of the year. The fundamental cause of condensation is that the surface temperature generally remains under the dew point. Water pump stations, valve chambers of the dams, underground water storage areas are some of these places where this problem comes up.
In such places, the supply of dry air below %40 RH would be enough to obtain the dew point value for the prevention of condensation.
In injection machines, for the removal of warming in mold area cooling is generally maintained by aqueous type of systems. In the mold surfaces which have been cooled condensation occurs due to high humidity navigating in the environment, especially in the summer season. This case, not only causes corrosion on the mold surface in time, but it also reduces the quality of the extruded products.
To fix the problem, humidity control throughout the manufacturing environment can be provided or it can be settled by blowing dry air, which will be obtained from a single unit, into the mold area through the taps.
Ensuring the supply of air at the critical dew point temperature necessary for emission optimization and providing ideal atmospheric conditions for painting halls.
Maintaining the required humidity and temperature balance for the integration of polyvinyl sheets onto glass surfaces during the lamination process.
Eliminating the corrosive effects caused by environmental conditions on bridge components, particularly the main supporting cables, deck, and tower interiors, to ensure long-term preservation.
Ensuring the secure protection of highly sensitive microchips, boards, and other electronic circuit components during manufacturing and interim storage processes against oxidation.
Protecting the product characteristics and quality of hygroscopic powdered chemicals from humidity-related problems.
Effectively conducting drying in enclosed spaces to maintain the construction schedule independently of the season.
