Additive filters for granulate dryers, side-by-side dryers<\/a>, top-mounted dryers<\/a> and central drying systems<\/a> reduce harmful deposits. Additives in plastic granulates always lead to evaporation or outgassing. These are caused by the specific chemical components of the processed plastic granulates. Such outgassing leads to unwanted deposits on or in machine components, which are detrimental to the service life of the equipment. It is known from practical experience that air hoses or air ducts in particular can become clogged with additive deposits over years of continuous operation. In such cases, there is a risk of dryer infarction.<\/p>\n\n\n\n

Compressed air dryers do not solve this problem because, unlike dry air dryers, they do not operate in a closed circuit and thus release the chemical components uncontrollably into the ambient air.<\/p>\n\n\n\n

In many cases, such additive evaporation can be minimised by optimising the setting parameters on the pellet dryer. These optimisations are necessary so that the additives develop their desired chemical and physical properties in the finished product. Drywell pellet dryers make these optimisations possible, as all relevant drying parameters can be set and stored. Should unwanted additive deposits nevertheless occur, the use of the innovative additive filter is recommended.<\/p>\n\n\n\n

To counteract harmful effects, Digicolor has developed a series of special additive filters. These are designed for installation in the return air stream of the pellet dryers. At this point, the filter separates outgassings from the return air and catches the unwanted components with a suitable filter element. This filter element is placed in a robust glass cylinder so that the contamination of the filter is visible. When the filter element is used up, it is easily and user-friendly replaced with a new element. The maintenance procedure required for this is carried out without tools.<\/p>\n\n\n\n

That is why it is recommended to use the additive filters<\/h3>\n\n\n\n
