VSA Oxygen Generators
VSA Oxygen Generators| How VSA Generators Work | Why Use Oxygen?
Our new VSA generators take the benefits of using oxygen in aquaculture a step further. The generators have been designed to be low maintenance and reliable systems, just what fish farmers need. Our new patented VSA (vacuum swing adsorption) generators offer benefits to the fish farmer.
- Simple installation
- Simple operation
- Easy maintenance
- High degree of mobility
- Constructed from standard components
- Only three moving parts – motor, valve and blower
- Three phase or single phase power
- Auto restart in the event of power failure
- Uses less power than PSA generators
No air compressor or air dryer is required, so operating and maintenance costs are reduced.
Oxygen technology has now become economical for most aquaculture operations, including ponds, raceways, re-circulation systems, flow through, hatchery operations, sea cages and net pens, and bait and leisure fisheries.
The generators in our product range are compact (see specifications), come skid mounted as standard, and can be easily trailer mounted for ease of manoeuvrability around your site. The generators simply need to plug into a power supply and you can start producing oxygen instantly!
Our VSA generators allow you to have your own independent oxygen supply, ideal for remote locations. Not only do they remove the management costs associated with traditional oxygen supplies, but also provide a predictable and economic long-term oxygen cost. The new range of Air Products VSA generators will also help keep your costs under control and your productivity high.
Are VSA Oxygen Generators suitable for aquaculture?
Yes. Air Products range of VSA oxygen generators have been designed specifically to meet the needs of the aquaculture industry and deliver affordable, reliable oxygen. Air Products VSA generators are supplied in a single module (feed/vacuum blower, automatic valves, and a PLC control system). In the larger generators, a single adsorber vessel is free standing, as is the oxygen buffer tank, whereas in smaller units all this is integrated within the module. Various options are available to suit all power requirements. The generator can be skid or trailer mounted. For those applications where product compression is required, an oxygen booster compressor is supplied as a stand-alone skid. Each generator is packaged to simplify the generators installation such that it is literally “plug and play”.
Three sizes of VSA oxygen generators are available:
120 l/min, 40 l/min and 5 l/min units.
