Applications

Built for the systems your customers run every day

View all applications

Floor Heating

For: Homeowners · Property Managers · HVAC Contractors

Uneven loop temperatures and cold rooms usually mean scale, rust debris and biofilm in the loops. Loop-by-loop cleaning from the manifold restores design flow.

View application

HVAC & Chillers

For: Office Buildings · Hotels · Hospitals

Falling airflow and rising energy use point to fouled fan coils and scaled tubes. Deep cleaning restores heat-exchange efficiency and supply-air quality.

View application

Liquid Cooling Plates

For: Data Centers · Server OEMs

Data-center cold plates: micro-bubble stripping, power-circulation rinsing and passivation — restoring conductivity and differential pressure to installation-grade water quality.

View application

Mold Cooling Channels

For: Injection Molders · Toolmakers

Restore thermal balance and cut cycle time: micro-bubble stripping plus circulation flushing opens scaled cooling channels without dismantling the mold.
