Cooling & HVAC Loops
Biofilm prevention, cooling tower algae controls, heat-exchanger efficiency, and safety protocols for H2S and pyrophoric decontamination.
Operational Challenges
Cooling towers reject heat by evaporating water, which concentrates dissolved mineral salts. Left unmanaged, these minerals precipitate onto heat exchanger tubes as scale, or act as nutrients for biofilm and algae.
- Scale Build-Up: Reduces heat transfer index, driving compressor power consumption up.
- Microbiological Biofilm: Act as insulating layers and shelter anaerobic bacteria like *Legionella* or Sulfate-Reducing Bacteria (SRB).
- SRB Pitting: Anaerobic SRBs produce $H_2S$, causing rapid galvanic micro-pitting under deposits.
H₂S & Pyrophoric Iron Mitigation
In industrial loops exposed to sulfur compounds or crude chemical atmospheres, localized anaerobic biofilms can convert iron oxides into pyrophoric iron sulfide. When exposed to air during maintenance shutdowns, pyrophoric deposits oxidize rapidly and self-ignite.
