HPS Midi Fresh

HPS Midi Var is a spraying system designed to contain odors, abate dusts and cool outside environments.

Spraying process (Osmogenic Barrier)

Odors neutralization takes place through a spraying process (osmogenic barrier) with the help of dilution water and certified specific products, deprived of polluting agents.

Labiotest osmogenic barriers guarantee abatement efficiencies of odor concentration above 80%.

All the products used are tested and guaranteed by Italian and International research institutions

For a proper diffusion of the deodorizing products, it is necessary to use adequate spraying systems, in order to guarantee:

  • suitable micronization
  • suitable timingsuitable
  • times for activities
  • strategic diffusion

Main advantages

  • High deodorizing efficiency
  • No chemical substances polluting the environment
  • No use of substances yielding by-products
  • Components present do not oxidize and are not affected by air
  • No influence of visible and ultraviolet sunrays on the process
  • The products contain terpenes and natural essential oils that act as olfactometric indicators of optimal dilution

The most important aspect of osmogenic barriers is their capacity of treating both diffused and conveyed emissions.
