External surface treatment: after the sandblasting process, the vessels are painted with electrostatic guns inside special booths. To complete the cycle, the vessels are conveyed to the polymerization oven through a chain conveyor belt.
On request it is possible to customize the coloring.
Internal protection treatment: it has a high resistance to corrosive agents. The vessel first is subject to a cleaning pre-treatment, then an epoxy resin is applied by electrostatic guns, the process is completed in the oven at ~ 240 ° C. Vitroflex is a certified treatment according to the Ministerial Decree of March 21, 1973 and subsequent updates (CE D.M 174), suitable for contact with food substances and for personal use.
Internal and external treatment: particularly indicated when a strong protection against corrosion is required. High resistance to atmospheric agents, suitable for outdoor installation and in aggressive environments.
The galvanizing treatment is done by immersion for a fully protection of the internal and external surface. The galvanized vessels may present differences on color and appearance, in particular between bottom ends and shell. This doesn’t affect the quality of the product in compliance with the UNI EN ISO 1461.
