Oxygen for hot shops, flameworking studios and scientific glass shops of every size
The HVO System is a perpetual oxygen generator that automates your oxygen supply. Our proprietary logic controller senses stored oxygen pressure and turns the compressor and the attached oxygen concentrators on and off to keep up with demand. Your usage determines how often the system runs to generate oxygen. The on-demand production of oxygen means you can blow glass while the system fills. Each system is built with oxygen-rated, high-quality components, and is made to order with your studio’s specifications in mind.
Which High Volume Oxygen Model do I need?
The High Volume Oxygen system is modular and expandable, so your initial investment can always be grown to support you as your business grows. Our team is more than happy to talk with you to help you decide which model and components will work the best for your studio space. Feel free to reach out to talk oxygen.
HVO Mighty Mite Classic Plus
The Mighty Mite is perfect for studios and shops with one or multiple torches running at high pressures.
The system can be paired with up to four 10 lpm oxygen concentrators and cycles on and off between 100 psi – 160 psi.
Runs off of household 110v electrical. (Built to electrical specifications of your shop.)
HVO Titan 1 Classic Plus
The Titan 1 supports up to six 10 lpm oxygen concentrators and is a great solution for larger shops with multiple torches running at once, or for longer class times in universities and institutions.
It cycles on to refill the tanks at 100 psi and turns off at 160 psi.
Runs off of household 110v electrical. (Built to the electrical specifications of your shop.)
HVO Titan 2 Classic Plus
The Titan 2 supports up to seven 10 lpm oxygen concentrators and is best for very large studios with multiple torches running for long periods of time.
The system cycles on to refill at 100 psi and turns off at 160 psi, with an optional restart at 130 psi and a high set point that can be adjusted to turn off at 175 psi.
Runs off of 220v with a NEMA L6-15P plug type. (Built to the electrical specifications of your shop.)

Oxygen Clean Tank Sizes
All models can be configured with the tanks shown at left. The larger your tank, the larger your oxygen storage capacity. More storage means more time using oxygen at a flow rate that is greater than the rate at which the attached oxygen concentrators can make oxygen. For example, if your HVO System has two 10 liter per minute (LPM) concentrators and your torch consumes 20 LPM, oxygen consumption is equal to production. If you turn the torch up to 30 LPM, you are now outpacing your concentrators, so your stored oxygen will diminish over time. If you increase your storage, either by using larger tanks, or by adding tanks, you’ll increase the time during which you can use oxygen at an increased flow rate.
Tanks are available in the following sizes:
- 20 gallon system – With this system you’ll want to match your input (LPM from concentrators) closely to your output (LPM used by torch), as there’s not a lot of excess storage. The HVO 20 is perfect for small spaces and portable shops, and can fit under your bench. Special order item only.
- 30 gallon system – This system has a small footprint while providing ample storage. It’s a good option for a one or two torch studio.
- 60 gallon system – This system greatly extends your burst rate working time. This is the minimum recommended configuration for working with Herbert Arnold and equivalent torches.
- 80 gallon system – This is our largest tank size — perfect for studios that want to maximize their space and storage requirements.
Oxygen Concentrators
We sell the following new (not refurbished or modified) oxygen concentrators:
- Airsep Onyx Ultra — (10 LPM)
- Drive DeVilbiss — (10 LPM)
All models provide 93-95% pure oxygen and include a factory warranty that covers service and parts.
How to Expand Your HVO System
The HVO System is modular, meaning that you can add components to your existing system to increase capacity. There are multiple options for expanding your system, each of which addresses a particular need.
Add Oxygen Concentrators and Relay Boxes
The sum of the flow rates of your oxygen concentrators equals your sustainable flow rate. If your goal is to increase your sustainable oxygen flow rate (i.e. your liters per minute), adding concentrators may be your best option.
Each HVO compressor has a maximum LPM of input that it can accept, which we refer to as the “Compression Capacity”. This indicates the number of concentrators per system.
- For the Mighty Mite compressor, the limit is *36 LPM, or four 10 LPM concentrators.
- For the Titan 1 compressor, the limit is *54 LPM or six 10 LPM concentrators
- For the Titan 2 compressor, the limit is *63 LPM or seven 10 LPM concentrators
- For the FLEX compressor, the limit is *82 LPM or nine 10 LPM concentrators.
If you exceed the maximum number of concentrators for your configuration, you can add a Drone, storage tank, and additional concentrators.
*We recommend operating your 10 LPM concentrators at 9 LPM to increase the oxygen concentration
Add a Drone
A Drone is a compressor controlled by the Main. It is used to add compression capacity so that you can connect more concentrators to your system. A Drone includes a tank and a compressor that responds to a signal from the Main to turn on and off. The Main and Drone tanks are connected via a braided steel oxygen line (included) to create a single “atmosphere” that has a common pressure. This pressure is sensed by the Main to maintain the pressure in all tanks within the range that is appropriate for your system (100 – 160 PSI for all compressors except the mini, which has set points of 55 – 100 PSI).
The Main and Drone(s) may employ any compressors except the mini (due to pressure limitations).
Add a Storage Tank
You may want to increase your storage by adding a tank that connects to your Main tank. This is useful when the flow rate from your concentrators is sufficient most of the time, but you have the occasional need to exceed that rate.
Add a Backup-Oxygen Supply Valve
This product allows you to keep compressed or liquid tanks on standby to supplement your HVO system’s capacity. This is useful in a variety of scenarios, including:
- When you plan to hold an event in your studio and you need to attach more or bigger torches than your HVO system was designed to handle.
- When you have a big project that requires higher-than-normal oxygen usage.
- When you want to reduce your oxygen cost, but can only afford a small HVO System to start.
