KEEP 20, KEEP 45 and KEEP 90 Systems
Efficient oxygenation for large biomass fish farms.
OPTIMAL OXYGEN SUPPLY
The KEEP 20, KEEP 45 and KEEP 90 systems provide 20 kg/h, 45 kg/h and 90 kg/h of oxygen, respectively. With a transfer efficiency of more than 95% at 8 meters depth, they are ideal for advanced stages of cultivation and veterinary management.
PERMANENT INSTALLATION OPTION IN LOW OXYGEN CONDITIONS
It can be permanently installed in cages in the culture center exposed to water bodies with low oxygen content.
Maximum biomass reference for low oxygen:
Keep 20
100 ton
Keep 45
345 tons
Keep 90
600 ton
- High tensile strength.
- High resistance to biofouling.
- High efficiency in gas diffusion to water.
- High oxygen delivery capacity.
- Fast installation.
- Lightweight.
- Transportable.
We keep alive large biomasses exposed to significant decreases in the concentration of dissolved oxygen in the water column.
Optimal oxygenation in cultivation units in critical situations with the Keepex system
The Keepex oxygen diffusion system provides adequate oxygenation in culture units at critical times such as algal blooms, low dissolved oxygen concentrations, harvesting maneuvers and therapeutic treatments with closed canvas.
Improvements in production variables
The use of pure oxygen in fish farming can improve productive variables since a higher concentration of dissolved oxygen in the water column increases appetite, improves conversion and decreases stress.
Efficient supply in all cages of the cultivation center
Our system allows the transformation of liquid oxygen into a gaseous state by means of a submerged vaporizer. This ability to vaporize large flows of oxygen ensures adequate supply to all cages in the culture center.
Microperforations and bubble size
Each KEEP system has 6,000 microperforations per meter for optimal oxygen diffusion in the form of 90-250 μm microbubbles.
On-site specialist service
We offer an on-site technical service to address the specific needs of our customers in an efficient and personalized manner.
Extra accessory for KEEP diffusers
Surge chamber
Developed to mobilize microalgae-free water to the surface by means of macro-bubbles, thus reducing the concentration of microalgae in surface waters and reducing their destructive potential.
Integrated oxigenation and upwelling diffusion system
The system offers several advantages by combining a highly efficient oxygen diffuser with an upwelling generation device in a single unit. This eliminates the need to add more elements to the cages, as the diffuser meets the oxygen requirements of the fish, ensures dilution to reduce the effects of microalgal blooms, and meets insurance company standards, which require at least 35 CFM per cage to mitigate such effects. The diffuser has an oxygen chamber to connect the diffuser hoses and a separate air chamber to generate the upwelling.
- System with high water movement water movement.
- Easy installation and transport.
- High durability.
- One-year warranty.
