Preserving wood from attack by atmospheric and biological agents such as fungi, insects and bacteria.<\/strong><\/h2>\n

Vacuum impregnators IMP-PG:
\nideal for window frames, grills, shutters, doors or loose elements.<\/h3>\n

The IMP-PG vacuum impregnators<\/strong> by ISVE were designed with the specific purpose of preserving wood from attack by atmospheric and biological agents<\/strong> such as fungi, insects<\/strong> and bacteria<\/strong>.<\/p>\n

In fact, these impregnation plants enable the optimal application of specific protective treatments<\/strong>, chosen according to the type of wood and hazard class. All this without disrupting the natural characteristics of different wood species.<\/p>\n

The possibility of employing waterbased impregnators<\/strong> and the spraying<\/strong> of the product in a hermetically sealed autoclave<\/strong> also means absolute respect for the environment<\/strong>.<\/p>\n

Treatments Hazard Class: up to 3<\/strong>.

How IMP-PG systems work<\/strong><\/h2>\n

The pieces to treat are hanged to a moveable frame and put into the autoclave, which after having been hermetically closed, performs the process by an automatic sequence consisting in:<\/p>\n

    \n
  • an initial phase of vacuum to remove the air from wooden vessels,<\/li>\n
  • a further phase for the introduction of the preservative which is sprayed through the nozzles suitably positioned inside the autoclave so that the joinery is completely treated,<\/li>\n
  • final phase of re-setting at the atmospherique pressure.<\/li>\n<\/ul>\n

    The process may be set in order to obtain a more or less impregnation depth according to the quality requirements.
    \nGenerally it is possible to perform about 2\/3 cycles per hour.
    \nWith this plant it is necessary to immobilize a very slight preservative (about 60-70 litres).<\/p>\n

    The advantages of the IMP-PG systems<\/strong><\/h2>\n

    The use of the\u00a0vacuum impregnation<\/strong>\u00a0allows:<\/p>\n

      \n
    • a real immersion in depth of the preservative in the works, especially in the head areas of the timber and into the holes or cavaties where protection is most needed.<\/li>\n
    • a better fastening of the products on the wooden surface.<\/li>\n
    • no noxious pollution.<\/li>\n
    • no evaporation of the solvents which compose the preservatives.<\/li>\n
    • sensible savings of the preservatives and paints.<\/li>\n
    • the use, in the same plant, of a wide range of impregnating products for the protection or care against woodworm, termites, fungi, etc., for woods subjected to risk classes 1, 2 and 3.<\/li>\n
    • homogeneous protection of the wood against sunlight<\/li>\n
    • total protection against humidity and water<\/li>\n
    • homogeneous application of paints and total penetration of the resin into joints, cracks and weak areas (not protected by other processes)<\/li>\n
    • perfect penetration of the coating product even in the smallest porosities by applying the double vacuum (vac-vac).This allows a much longer life of the products than traditional systems.<\/li>\n
    • maximum seal between finish and base<\/li>\n
    • considerable reduction of the preparation time of the surfaces after the application of the base thanks to the very reduced phenomenon of the “lifting of the hair”<\/li>\n
    • recovery of all the product not applied on the pieces<\/li>\n
    • absence of processing waste.<\/li>\n<\/ul>\n

      These hermetically sealed and automatic cycle wood impregnators also eliminate the need for:<\/p>\n

        \n
      • use specialized personnel<\/li>\n
      • adopt expensive equipment for the treatment and filtration of paint residues<\/li>\n
      • consume more paint product than necessary<\/li>\n
      • carry out heavy checks to guarantee a constant quality value<\/li>\n<\/ul>\n
