Powered by NanoCav CAS® – Prasinos Tech’s patented hydrodynamic cavitation aerator for high-efficiency gas-liquid mixing.
Technology
NanoCav CAS® harnesses hydrodynamic cavitation within a precisely engineered static chamber to create intense gas–liquid interaction.
As fluid accelerates through the system, controlled pressure differentials generate cavitation zones where gas is finely dispersed into stable micro and nanobubbles. This results in enhanced oxygen transfer, deeper penetration, and uniform mixing across the entire volume.
No moving parts. Just pure fluid dynamics working at peak efficiency.

Cost Efficient Operation
Optimized hydrodynamics ensure low energy consumption for aeration, while the absence of moving parts significantly reduces maintenance and lifecycle costs.
Flexible Aeration Control
Available in multiple configurations and capacities, NanoCav CAS® systems can be tailored to suit diverse treatment requirements across industries and scales.
3-in-1 Functionality
Combines aeration, mixing, and reagent dispersion in a single unit—enhancing process efficiency while reducing system complexity.
Plug & Play Design
Factory-tested, skid-mounted systems designed for quick installation and immediate operation with minimal on-site integration.
Reliable & Low Maintenance
Static design eliminates mechanical wear and ensures long-term, uninterrupted performance with minimal service requirements.
