How much will I pay in electricity? (Part Three)

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 you can always add more concentrators or additional storage if you upgrade or need more oxygen, but this setup is a great starter system.

Generate Oxygen with Solar Power

Is it feasible and beneficial to run an HVO oxygen generating system with photovoltaic (PV) solar panels? That is the topic I’ll be exploring in this post. I consulted with professional solar installers on the technical questions regarding modern PV solar systems.

The cost of PV solar power has come down 99% over the past 40 years. Meanwhile, “conversion efficiency“, which represents the amount of sunlight that is converted to electricity, is now as high as 22.8%. To bring the cost down even further, state and federal governments offer Renewable Energy Tax Credits.

How much will I pay in electricity? (Part Two)

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).
