PureTech filtersPure rPET packaging. The filter against VOC

Float block image puretech filters

PureTech is the Piovan high-tech patented filter for Genesys dryers that allows a reduction of the VOCs in the process air. This is especially required when using recycled materials that can release substances during the heating or injection process.

The NIAS (non-intentionally added substances) normally found in rPET originate from foreign materials (paper, metals, glass, organics, environmental dust, and sand), from additives, and from different immiscible polymers (PS, PVC, PE, PP, ABS and so on) that arise from sorting mistakes and packaging components. In particular, Benzene derives from the rearrangement of terephthalic groups with acids, such as the hydrochloric one, that, in turn, come from chlorine component of PVC.

PureTech filters reduce consistently the amount of NIAS in the process air. By limiting the amount of substances that can settle on the pipes or condensers surfaces and molecular sieves, the advantage obtained is the production line lifespan maximisation.

PureTech filters are composed of activated carbons chamber, stainless steel frame, nanotech paper layer and seals.
