FAQ - frequently asked questions
How much area is needed?
For a typical module of 60–120 m³, 120–250 m² will be required, taking into account passages, filtration and shield.
What is the water consumption?
Water exchange is usually 3–5% per day. A salt unit and water preparation are required.
Can it be scaled?
Yes, modules are added sectionally, we lay out pipelines and electrics with a reserve.
What is included in the PNR?
Installation, startup, automation setup, personnel training, package of regulations.
