NITROX, Oxygen Membrane systems

onsite production of Air & NITROX for

surface supplied diving  

 

The fully automatic membrane and CO2 reducer system, separate Nitrogen and CO2, to make enriched air Nitrox, from 32 to 40% mix with an accuracy less than 1 %

Nitrox system with: LP compressor - Airdryer - LP filter system - CO2 reduer - Membrane unit - HP compressor - HP filter system - Analyser system with log.

Information about CO2" in NITROX

Constantly rising amounts of CO² as well as adverse environmental conditions, create harmful levels of CO² concentration in the air. For operators of NITROX filling stations, it is becoming increasingly difficult to reliably comply with the legally-binding CO2 limits.  

The proportionally increasing amount of CO² in all NITROX membrane systems also makes compliance more difficult.


The solution is a´  CO2 REDUCER  from KrinnAir

NITROX membrane systems

Installed in diving Vessel

Nitrox membrane system can be designed to be a part of the Air supply system, so it is possible to make both air and NITROX with the same HP compressoer.

It is possible to make from 32 to 40% NITROX, in 250 L/min and up to

450 L/min.

It can be stored on onboard cylinders which can supply NITROX to the diving control panel.

Containerized, so it can be part of any dive spread

10 or 20 feet container, integrated with Low pressure compressor &

CO2 reducer & Nitrox membrane and HP bauer compressor, all in one unit.


20 feet container can also be equiped with 158L composite gas cylinders, so the Nitrox are stored temperate and safe inside, one unit that is easy to transport

CO2 reducer 

The KrinnAir - CO2 reduser unit, removes CO² safely from the breathing air before NITROX is created in the membrane system.

This means that the NITROX complies with the DIN EN 12021 limits and

it means that there are removed more than 1000 ppm CO2 in the NITROX
