How PCI Gases Oxygen Systems Enhance Water Quality in Aquaculture
Boosting fish health, feed conversion, and sustainability through reliable on-site oxygen generation
A Breath of Fresh Air for Aquaculture Operations
Oxygen is essential to healthy aquaculture environments. From fish hatcheries to large-scale offshore farming operations, maintaining optimal dissolved oxygen levels directly affects animal health, growth rates, and operational efficiency. PCI Gases offers advanced on-site oxygen generation systems designed to meet the demanding oxygen needs of aquaculture — with cost-effective, sustainable, and scalable solutions.
Our PCI On-Site Oxygen Generators: A Better Way to Aerate
Unlike traditional oxygen supply methods like liquid oxygen deliveries or bulky gas cylinders, PCI’s oxygen generators use Vacuum Swing Adsorption (VSA) technology to produce high-purity oxygen on demand. This eliminates delivery delays, reduces costs, and improves safety.
Aquaculture systems benefit from:
- Constant oxygen availability
- Reduced energy consumption through low-pressure delivery
- Fewer fish mortalities during transport and handling
- Improved feed conversion ratios (FCR) and fish welfare
PCI’s DOCS oxygen generators are ideal for both land-based RAS (Recirculating Aquaculture Systems) and marine cage farms.
Designed for Harsh Environments, Built for Reliability
PCI Gases oxygen systems are rugged, easy to install, and require minimal maintenance. They operate efficiently in coastal or offshore locations with minimal infrastructure, making them ideal for remote aquaculture farms.
Use cases across the world — from shrimp farms in Asia to salmon operations in the Americas — have proven that oxygen-enriched water leads to:
- Faster fish growth
- Lower disease rates
- More efficient waste breakdown in biofilters
Why Aquaculture Companies Trust PCI Gases
Aquaculture demands oxygen, and PCI delivers it with reliability and control. With customizable systems that scale to farm size and oxygen demand, PCI ensures you never run out — and you only pay for what you need.
VSA Technology
To produce oxygen from air, PCI uses a proprietary Vacuum Swing Adsorption (VSA) process that eliminates many of the design problems associated with traditional on-site gas separation systems (PSA). Our innovative VSA system eliminates the need for process valves, feed air compressors, associated dryers and feed air filtering systems. Our robust VSA oxygen process extracts maximum sieve and power efficiencies = low cost (both CapX and OpX) high purity oxygen generation. Oxygen produced is 93% purity. Additional product/systems features include load following, remote monitoring and diagnostics along with an industry only 10-year warranty on the adsorber bed vessel. Average life span of our systems is 10-15+ years.
