Create your own compressed oxygen. For flameworking studios and scientific glass shops of every size.
The HVO System is a perpetual oxygen compression system that automates your oxygen supply. It comes complete with a compressor, controller, storage tank, relay boxes and manifold lines. 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. Each system is constructed of oxygen-rated, high-quality components, and is built to order with your studio's specifications in mind.
Tank Sizes and Dimensions
All models can be configured with the tanks shown below. 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 (oxycons) can make oxygen. For example, if your HVO System has two 10 liter per minute (LPM) oxycons 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 oxycons, 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.
Storage tank sizes and overall system dimensions are shown below:
We sell the following new (not refurbished or modified) oxygen concentrators:
Both models provide 10 Liters per Minute (LPM) of 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 Oxycons and Relay Boxes
The sum of the flow rates of your oxycons equals your sustainable flow rate. If your goal is to increase your sustainable oxygen flow rate (i.e. your liters per minute), adding oxycons may be your best option.
Bear in mind that your HVO system has a limited LPM input per HVO model. This breaks down to a limit on the number of oxycons per system. For the MAX compressor, the limit is 55 LPM or six 10 LPM oxycons (we recommend operating your 10 LPM oxycons at 9 LPM to increase oxygen purity). For the Mighty Mite and Standard compressors, the limit is 45 LPM, or five 10 LPM oxycons. If you go over that number, you'll need a drone and tank combination.
Add a Drone / Naked Drone
An HVO Drone is used to add compression capacity when the number of oxycons exceeds the capacity of the Master compressor. A Drone includes a tank and a compressor that responds to a signal from the Master to turn on and off. The Master 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 Master to maintain the pressure in all tanks within the range that is appropriate for your system (30 - 100 PSI for the Standard, 100 - 150 PSI for the MAX and Mighty Mite).
When adding a Drone, pair a Standard Master with a Standard Drone. Mighty Mite and MAX products may be combined.
A Naked Drone is a reduced cost Drone. The significant difference is that a Naked Drone is cheaper overall, but requires an extra outlet on one of your relay boxes, whereas a "dressed" Drone can plug straight into household power. The Naked Drone does not come with a green head box, i.e. its parts are exposed (but still safe).
Add a Storage Tank
You may want to increase your storage by adding a tank that connects to your Master tank. This is useful when the flow rate from your oxycons is sufficient most of the time, but you have the occasional need to exceed that rate.
Add a Peak Patch Kit
The Peak Patch Kit 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. Here are a few examples:
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.

Gas Flow Calculator
See our Common Packages page for HVO System configurations that may suit your needs. Each HVO System is specified for the shop or studio it will run based on the torches being used and the approximate amount of oxygen you go through. While the sample configurations and Return of Investment Calculator can give you an idea of what system may work for you, it’s a great idea to get in touch so we can help you figure out the best solution for your situation!
