BANKNOTE DISINFECTION SYSTEM

Spectra Systems’ patent pending technology utilizes a combination of a heat and oxygen-free environment to neutralize (> Log10 = -6 reduction of viral load ) SARS-CoV-2, and other viral and bacterial pathogens, while protecting the banknote’s substrate, inks, and security features. The system is effective with both paper and polymer substrates.

The complete system has the capacity to disinfect between 4 million and 6 million notes in 1-2 hours with no consumables as oxygen is extracted from air. Banknotes can remain in strapped or shrink wrapped form for efficient workflow, enabling the disinfection of 15-20 million banknotes in an eight hour shift.

BDS-1000 BANKNOTE DISINFECTION SYSTEM

The BDS-1000 is comprised of two primary subsystems:

  • a custom designed large scale oven unit with oxygen sensors and timing controls.
  • a pressure swing adsorption (PSA) nitrogen gas generator.  The PSA extracts oxygen from the ambient air and produces a nitrogen atmosphere within the disinfection oven.
