Lowest Oxygen Cost per Unit

HVO has been making oxygen-generating systems for commercial applications since 2011, and is an emerging leader for systems that produce up to 300 LPM. In recirculating aquaculture systems, generated oxygen is much less expensive than truck-delivered oxygen, whether liquid or compressed.
HVO systems provide the lowest cost per unit of oxygen:
- Less costly than all other oxygen generating systems in the 10-300 LPM range
- Less costly than compressed tanks
- Less costly than liquid O2
Actual savings will depend on the configuration and the cost of power in your region. Use the quote tool below for details.
Advantages of Generated Oxygen

Multiple concentrators working together provide redundancy and reliability. The loss of any single concentrator can be sustained while continuing to deliver oxygen. Compare this to monolithic oxygen-generating systems that require expensive, redundant components to provide continuous operation.
- HVO systems are modular and expandable, permitting you to grow your oxygen-generating capacity while preserving your original investment.
- The use of off-the-shelf oxygen concentrators facilitates redundancy, increases reliability, and lowers the overall cost. We sell new Respironics and Airsep concentrators, but other models of oxygen concentrators may be used.
- No air dryer required. Air driers with screw compressors are expensive and they represent a single point of failure in large oxygen-generating systems.
Perfect for Fisheries and Hatcheries

In the aquaculture industry, oxygen requirements often change over time. The ideal solution is a scalable oxygen-generating system that can expand in small increments while preserving existing components.
Each system includes a compressor, digital logic controller, storage tank, relay boxes and manifold lines. It is also available with the Seeing Eye(TM) Cloud Monitoring Service.
The HVO system fully-automates the oxygen generating process. It automatically turns the compressor and the attached oxygen concentrators on and off to keep pace with demand.
Your usage and configuration will determine how often the machine runs to generate oxygen. Generally, systems should be configured with enough capacity to exceed the peak anticipated flow rate.
Each system is constructed of oxygen-rated, high-quality components, and is built to order with your operation’s specifications in mind.

The Pro Series model includes an LCD/LED panel that provides at-a-glance details about oxygen purity and tank pressure. The Seeing Eye(TM) cloud-based reporting and monitoring solution provides you with email and text notifications to alert you about issues such as a power outage, loss of Internet service, changes in oxygen purity, and low tank pressure. In addition, this option enables you to look at a real-time graph of your system’s status using your phone, tablet, or desktop computer.
Frequently Asked Questions
Is generated oxygen cheaper than liquid oxygen (LOX) for aquaculture?
Yes, in the 10–300 LPM range. On-site generation with an HVO system costs less per unit of oxygen than liquid O2, compressed cylinders, or other generating systems of similar capacity — an HVO system produces a K-tank equivalent for under $2 in electricity. Actual savings depend on your configuration and local power costs.
How much oxygen does a RAS or hatchery system need?
Systems should be sized so capacity exceeds your peak anticipated flow rate. HVO systems scale from 10 to 300 LPM and are modular, so a hatchery can start small and add concentrators, Drone compressors, and tanks as stocking density grows — without replacing existing equipment.
What happens if a component fails while fish are in the water?
HVO systems use multiple independent oxygen concentrators, so losing any single concentrator does not stop oxygen delivery. Pro Plus systems add Seeing Eye™ cloud monitoring with text and email alerts for low tank pressure, purity changes, power outages, and internet loss — readings update every 10 seconds.
Do HVO systems require an air dryer or three-phase power?
No. Unlike skid-mounted oxygen plants, HVO systems need no air dryer (a common single point of failure) and run on single-phase 120/240 VAC power. An 80-gallon 70 SLPM HVO system weighs 325 lbs versus roughly 2,200 lbs for a comparable skid-mounted plant.
What’s included with an aquaculture oxygen system?
Each system includes a compressor, digital controller, oxygen-clean storage tank (30, 60, or 80 gallon), relay boxes, and manifold lines. Off-the-shelf concentrators keep replacement costs low and the system fully automates generation to match demand.
