The problem of the environingingmental humidity begins from the storage of the plastic material. Where enormous quantities of material owe to be lists at all times, silos external are used together with octavines and sacks. These containers can be instrumented with mechanisms of protection that warn the penetration of the humidity. But no all the users need bulky containers.

Material stored in stock exchanges, mobile containers or octavines are constantly exposed to the risk to absorb humidity – especially in the cases where the containers remain opened by a period of time, for the feeding of scheme them procesadoras.

Sacks lined with paper aluminium can resolve this problem until some degree, although the content has to be processed so fast as it was possible once that the sack is open. For low consumptions, are used mobile dryers to confront the humidity in these cases. For some materials, a handle special is required after the process of dried to feed scheme it procesadoras, and like this delete the risk of rehumectación.

To ensure a flow optimo of material through the pipe in applications of transport of materials, a suitable proportion of air has to accompany the material, and usually the environingingmental air is used for this purpose, therefore, a humectación unwanted of the material can occur during the transport in the pipe.

In systems of handle of materials, this is warned with transport of dry air. In this case, any quantity of environingingmental air is aspired in the boxes of succión, if no that the material is transported through an enclosed circuit of air using a soplador central. For these cases, the mobile dryers Wittmann of the series Drymax And with the option “PDC” fulfil all the important requests. Of equal form, the dryers of wheel divided of the series Aton are instrumented with what knows like “BS/6 integrated cheese cheese”.

In warm season, the demand of equipment generators of dry air increases just like the demand of fans and air conditioned in summer. The greater concentration of humidity in the air during said season affects considerably in the processed of hygroscopic resins.

The cold season also represents some challenges by himself same. For example, The PP requires of elder dried more and of form more frequent. It is true that a lot of manufacturers and providers of resins agree in that the PP does not require to be dried. But the experience shows that the dried of said resin is very common in a lot of cases.

When it asks them on the reason, the most common answer: the consistency in the quality of a product only can be reached when keeping the same conditions.

For example, if the material is stored to low temperatures in an environingingment without heating, the predominant  conditions are totally different to those to warm temperatures. The change of the conditions is even more extreme with the storage to the intemperie, when the temperature falls underneath of the 0 °C. In the practice, the PP and PA are always dried, without mattering of the station of the year.

The Drymax Aton with wheel of dried divided of Wittmann, quickly has established in all the climatic zones of the world, in North and Sudamérica as well as in Asia, Australia and Europe. The processors appreciate particularly to the Drymax Aton by his constant behaviour of the point of rocío and excellent quality of the dry air, which supplies even under extreme environingingmental conditions, besides with an invariabilidad that increases the quality of the material.

Like global provider, Wittmann demands to himself same an optimum performance of dried in his equipment, without mattering the climatic zone. The Drymax Aton is particularly appreciated by effectiveness when confronting the high concentrations of humidity in tropical zones, where some times the water literally “beads of the walls” in the ships of production.

In temperate zones, the most important characteristic of the Aton is his energetic efficiency. The correlation between the material dried and the consumption of power is easy to illustrate when comparing it with the consumption of petrol of an engine of car.

A car of career will be the swiftest in arriving to put it if it is driven to maximum speed, consuming one some quantity of fuel in the process. However, also it would cover the same distance to a lower speed, what would represent a reduction in the consumption of petrol. And east is precisely the type of activity that realises the Drymax Aton, choose between working to maximum power and work more slowly. With only presses a button, the team went in in the modality Echo- Mode, which provides an automatic control of the process.

Every time that the load of humidity is high, the dried llevar in the rotary presses wheel divided. And so prompt like the load of humidity diminishes and improve the conditions of dried, the Aton automatically changes to the cartridge of dried and the wheel divided detains , and like this, reduces the consumption of power. In addition to the EcoMode, the Drymax Aton has additional characteristics designed to reduce the consumption of power.

For example, the special process 3-Save reduces the consumption of power to the reutilizar the heat in the process. On the other hand, the element of heating finds located for exchange of heat and of optimum air. And finally, the Drymax Aton also uses the method checked of regeneration previously known for other models of dryers of Wittmann. To realise the process of regeneration so short and efficient possible, the function called SmartReg commissions of the appropriate control of temperature as well as the optimum synchronisation of the all the cycle.

Drymax Aton Can operate with silos of dried of different sizes. Besides, they have taken different measures to reduce the cost of power. The silos of stainless steel are isolated térmicamente, and the element of heating finds mounted directly on the silo to avoid the loss of heat. In mobile equipment, with 2, 3 or more silos, the valve SmartFlow regulates automatically the distribution of air, said characteristic is standard. Then why we would have to follow supplying and heated more air of the necessary?
