R-30 Aeration Unit

Our rapid aeration technology connects to the Bioquell L-4 to help remove hydrogen peroxide vapor after a bio-decontamination cycle. This can reduce cycle times.


Dispensing Head

As an option, a distribution head allows additional decontamination of rooms, for a volume of up to 350m3.

Bioquell Booster Fan 

Give your system extra capacity to bio-decontaminate large filter bank enclosures in less time, and with reduced hydrogen peroxide consumption.

Bioquell Hydrogen Peroxide

Bioquell HPV-AQ

This is a 35% aqueous hydrogen peroxide solution used in Bioquell technology to generate hydrogen peroxide vapor, which achieves a 6-log sporicidal kill on exposed surfaces.


Bioquell Biological Indicators (BIs)

Our biological indicators are made from Geobacillus stearothermophilus endospores to help you validate a Bioquell decontamination cycle. Easily confirm that you’ve achieved a 6-log sporicidal kill.


Bioquell Room Chemical Indicators (CIs)

Confirm that a Bioquell cycle has achieved the expected vapor distribution and exposure performance with these easy-to-read chemical indicators. A chemical strip reacts to a Bioquell cycle and changes color to correlate with the cycle's expected efficacy. For use in rooms and enclosed areas 10m3 and larger.

Bioquell Validation


To meet regulatory requirements, you may need to deliver proof that your bio-decontamination solution performs as it should. Ecolab provides trained engineers and the validation documentation you need to comply with regulations.

Use Even on Sensitive Electronics and Equipment

Our hydrogen peroxide vapor is tough on microbial surface contaminants, but gentle on electronics and equipment. Unlike spray-and-wipe methods, there are no additional steps to remove residue. When you need to bio-decontaminate spaces that contain hard-to-clean equipment, Bioquell is ideal. Before using Bioquell on your electronic equipment, check with the manufacturers to confirm compatibility.
