HVO System Models
The HVO System is an All-In-One, perpetual-oxygen solution that comes complete with a compressor, controller, storage tank, relay boxes and manifold lines. The system fully-automates the oxygen generating process, turning the compressor and the attached oxygen concentrators on and off to meet the downstream demand. Your usage determines how often the machine 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 new (not refurbished or modified) Respironics M10 oxygen concentrators with a 3 year warranty. Each concentrator provides 10 LPM of 95% (+/- 3%). Includes a 3-year factory warranty, service and parts. You can find refurbished and used oxygen concentrators from other suppliers, but we've found the Respironics M10 to be the best in terms of reliability and oxygen purity. If you decide to purchase oxycons from another source, note that the amperage requirements are roughly the same between 5 and 10 LPM units.
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 compressor. This breaks down to a limit on the number of oxycons per system. For the MAX, 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, 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
A Drone is a compressor that is mounted on a storage tank. Its job is to take orders from the master to turn on and off so that the entire system (all compressors and oxycons) can work in coordination. The drone tank must be connected to the master tank via a braided steel oxygen line (included) to create a single "atmosphere" that has a common total 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.
What are the manufacturer recommendations for my torch?
