Oxygen concentrators and air driers are often needed in Aquaculture to pre-treat the gas flowing into ozone generators.
Oxygen concentrators are a versatile and reliable way to add oxygen to aquaculture systems, and oxygen concentrators are highly beneficial when operating ozone generators. By drying the air alone the performance of an ozone generator is increased above using atmospheric air, and by concentrating the air you can improve ozone output in both volume and concentration by up to 5 fold.
By adding concentrated oxygen to either an oxygenation stream of an ozone generator, it creates a better transfer into the contact vessel, contact vessels do not need to be as big (as gas flow is reduced compared to use air) and under high pressures, there is no concern of nitrogen supersaturation.
Pure Aquatics have also developed a dual chamber air drier that has a fine pleated cartridge and a indicating dessicant media for removing moisture for placing before ozone generators and as an optional upgrade to oxygen concentrators to extend their service life and improve performance.
Oxygen concentrators and air driers should always be utilised for effective long term production of oxygen and ozone.
Invacare Oxygen Concentrators
Invacare oxygen concentrators are a robust option for small scale oxygen supply (up to 9lpm) in an affordable package.
Oxygen purity ranges for 87-96% across their range of output and are easy to clean to maintain.
Available in 5LPM and 9LPM outputs to suit most small to medium demands and for supplying ozone generators.
Available as an optional extra, Pure Aquatics now offer is an after market filtration upgrade for the suction side of the compressor that filters air to 1 micron, with much larger surface area. This improves service life and output of the oxygen concentrator for a small increase in cost.
Air drier assembly
The Pure Aquatics air drier assembly is for use for pre treatment of air for ozone generators and oxygen concentrators.
- Twin clear 10″ housing
- Flow rate up to 10lpm
- Course inlet filter
- 1 micron pleated Pre filter
- Silica desiccant indicator gel cartridge with 1kg of media (changes pink when saturated)
- 3/4″ female fittings for flexible installation option
Ozone generators: If running an ozone generator on air, it is important to filter the incoming air and strip moisture from it to prevent production of nitric acid, prevent damage to the corona cell, and increase output. Oxygen Concentrators: In some applications excess moisture can be present in the air that can cause premature exhaustion of sieve beds in oxygen concentrators, by filtering the air to 1 micron, excess dirt, dust and salts are minimised increasing the efficiency of the oxygen concentrator, the addition of the desiccant media strips moisture from the air further protecting the seive beds in the oxygen concentrator.
