As vehicle HVAC systems work harder during hot weather, components such as evaporator cores, condensate drains, air ducts and cabin air filters can become environments where microbial contamination develops.
BioCote conducted testing on behalf of one of the leading Automotive Manufacturers against microorganisms associated with automotive HVAC systems.
The results showed:
> 99.99% reduction of Staphylococcus aureus after 24 hours
> 99.97% reduction of Escherichia coli
> 99.99% reduction of Methylobacterium mesophilicum
> 99.99% reduction of Ralstonia pickettii
> 99.99% reduction of Chelatococcus asaccharovorans
> 96.63% reduction of Sphingomonas paucimobilis
These microorganisms were selected because of their relevance to automotive HVAC environments and their potential contribution to odour development and contamination.
For OEMs and Tier 1 suppliers, this demonstrates how BioCote antimicrobial technology can support long-term HVAC system performance by helping to reduce microbial build-up on treated surfaces.
