By Dennis Kornbluh, CTO, High Volume Oxygen Abstract: This post explains the benefits of maintaining a historical record of minute-to-minute oxygen flow rates. It shows how time-series graphs reveal oxygen consumption patterns, and how these patterns may be correlated with specific activities and events. It explains how a summary of total oxygen usage by week or by month can help to reconcile gas company bills, or plan for the implementation of a new oxygen solution, such as transitioning from compressed cylinders to liquid oxygen (LOX) or an oxygen generator. A scenario is described that illu ..read more

Add up to five 10 lpm oxygen concentrators to the Mighty Mite 20 gallon system In previous posts, we’ve examined the electrical usage of a large studio setup and a medium studio setup. In this article, we’re looking at a small High Volume Oxygen system for a single torch – the Mighty Mite 20 gallon system with two HVO Pro Gen 10 lpm oxygen concentrators. This small setup works great for someone working with a Bethlehem Bravo or GTT Phantom. It could handle a couple of folks working on smaller torches like Bethlehem Alphas or GTT Lynxs. High Volume Oxygen systems are modular and expandable, so ..read more

When considering a High Volume Oxygen system to replace your dependence on compressed or liquid oxygen tanks, there are various considerations. Knowing how much oxygen you go through in a set period of time is a great way to figure out which High Volume Oxygen system will work best for you. It helps to know how long a tank of oxygen lasts you, but short term usage is also helpful to make sure you get a system that can keep up with you. How do you figure out your short term usage? Start with your torch(es). What are the manufacturer recommendations for my torch? When looking at how mu ..read more

Why would you want to supplement your High Volume Oxygen System with compressed oxygen tanks? When considering a High Volume Oxygen system to replace your dependence on compressed or liquid oxygen tanks, there are various considerations. One of the most important things to consider is your typical overall oxygen usage vs your peak oxygen usage (the highest volume of oxygen you might need during certain time periods). When making your initial investment, sometimes it makes more sense to plan for your typical oxygen usage and supplement with compressed oxygen for the rare occasions that your usa ..read more

High Volume Oxygen of Lincoln, Nebraska was selected by the Ford Motor Company to help in the development of a portable emergency oxygen generating trailer that can be deployed strategically to field hospitals and other locations where oxygen supply may be disrupted. High Volume Oxygen is an industrial oxygen equipment manufacturing company based in Lincoln, Nebraska that serves the veterinary, aquaculture and glass blowing markets with state-of-the-art oxygen systems that closely monitor metrics in the cloud, such as volume, flow, and oxygen purity, that are essential for life supporting oxyg ..read more

In the continuing discussion of the electrical usage and costs of a High Volume Oxygen system, I wanted to share a modified configuration of the Lincoln Hot Glass system with different torches working on it. The configuration of the system and the torches working on it will affect the electrical costs. A larger system that needs to turn on fewer times to refill will have lower electrical costs than a smaller system that runs more often. The HVO configuration for this graph is a MAX 60 gallon system with a 60 gallon storage tank and five 10 lpm oxygen concentrators (or 50 lpm). How often is th ..read more

Many people are curious to know if their electrical bill will skyrocket after making the switch to High Volume Oxygen. When the HVO System is properly specified, it will cycle on and off. For most glass studios, the system may run for half of the workday, or it may run for a couple of hours. The size of the system, the components being run and the amount of oxygen being used are all considerations when figuring out how much you’ll be paying in electrical costs. Calculating Wattage To figure out your electrical costs, you’ll need to know the watts being used over a period of time and you ..read more

In part 1, we talked about the density of oxygen, gas measurement standards, and how to calculate gas volume for a container of a given size at a given pressure. In this post, we’re going to use that knowledge to configure an HVO system that is capable of producing the amount of oxygen that you require. Quick Summary Oxygen compresses in proportion to pressure. To accurately size your HVO system, you must know both the maximum flow rate and the regulator pressure that your application requires. The oxygen that you generate at low pressure will become more dense at a higher pressure. Inpu ..read more

When you buy a container of ice cream, you may think that a quart is a quart until you learn that one brand contains a lot more air than another. You can weigh the two containers and you’ll know that the heavier one contains more product. The same is true for gases: two tanks may be “full” from the top to the bottom, but the volume of stored gas is based on density, which is mostly determined by pressure. Like most common gases, oxygen expands to fill its container. But how much oxygen is actually inside? You may know that an oxygen cylinder contains some number of cubic feet of oxygen, bu ..read more
