8.5 HELIX System.
Compared to traditional nozzles the patented new-generation HELIX® system offers, for the same nozzle
dimensions, an increased tangential contact area, maintaining the action of the media on a given surface.
This makes it possible to increase the distance of the operator from the treated surface, minimising
invasiveness without losing the regularity and evenness of cleaning and avoiding the need for operators to
make constant corrections, which can result in definitive loss of the substrate being treated.
The heart of the patented HELIX® system exploits a combination of the Venturi effect, generated by a
special configuration of the outlet cone, with a device that induces a helical rotary movement, in order to
considerably reduce the air volume required to operate the machine. This has made it possible to enhance
the capacity of IBIX® equipment, which has always been known for its compact dimensions, lightness, low
compressed air and media consumption, which, in addition to economic savings, leads to ease of operation
on the worksite and extremely easy transport and handling. The use of special wear resistant steels and the
absence of mechanical moving parts means that the new HELIX® nozzle stands out for its durability even
when the use of very hard minerals like almandine garnet, corundum, etc. is necessary.
8.6 General points
A cleaning system using dry and wet micro-air-abrasion IBIX® equipment with controlled low pressure
projection of specific calcium carbonate based aggregates for cleaning artistic artefacts, of extremely fine
grain size (from 120 to 350 Mesh) and hardness less than 3 Mohs, or spherical almandine garnet (hardness
7.5 Mohs,) or vegetal blasting materials, or with sodium bicarbonate for non porous, scratchable, and glossy
surfaces; hardness to be selected on the basis of the type of substrate and form of degradation being
treated.
Operating pressure using compressed cooled and dehumidified air adjustable starting from 0.2 bar.
Micrometric adjustment of the compressed air/aggregate/vaporized water mixture. Light, ergonomic
application gun with interchangeable hard metal nozzles and internal aperture of diameters from 1 to 4.5 mm
cylindrical or conical, or with helical vortex technology for a HELIX® tangential-rotating abrasive action,
particularly recommended for use on decorative elements, friezes, mouldings, and recesses. Distance from
the artefact variable on the basis of the surface condition and the operating pressure.
