Halton Quattro Aero – Four-stage air purification unit

Halton Quattro Aero is highly efficient – four stage – air purification unit that is to be installed as a part of existing or new ventilation system. The unit purifies indoor air by eliminating microbes (viruses, bacterias, spores). The unit is installed in ventilation duct before or after Air Handling Unit (AHU) or Fancoil unit (FCU).

Independent tests show that Halton Quattro Aero eliminates microbes with 99 % efficiency (single sub-second pass). The latest tests were done at the Helsinki University laboratory in autumn 2020.

Halton Quattro Aero is an excellent choice for air conditiong system where it handles recirculation air. It eliminates microbies and is very cost efficient compared to many other systems.

Operation principle ^

The air passing through the UV-lights is charged with massive amount of ions. Additional ions are created by ionizer cassettes. Together with a small concentration of ozone they produce extremely reactive hydroxyl radicals. In the beginning the oxygen molecule gets a negative charge in photochemical reaction receiving a free electron forming a superoxide ainion.

The formed superoxide anion reacts further with humidity producing oxygen, perhydroxyl radicals and hydroxyl radicals. Hydroxyl radicals oxidize organic molecules.

Additionally, due to the UV-lights reaction, hydroxyl anions (OH-) and hydroxyl radicals are created which are both very antiseptic.
