Our customers are very important to us. They seem to like us, too!

It’s great to know that our oxygen generator is operating properly at all times. The real-time oxygen % and cloud notification is the best...safe and secure! I highly recommend the HVO Seeing Eye Oxygen Generator for all Animal ER’s and Specialty Centers.

We converted our two hospitals to the HVO-30 Seeing Eye Oxygen Generator several years ago and have never looked back. It is a huge benefit not to be dependent on the oxygen suppliers and we save hundreds of dollars each year, particularly in our ER where we used to go through an H tank in a day, the HVO Oxygen Generating System is the only way to go!

I love the quiet, automatic operation of my HVO Seeing Eye Oxygen Generator. We always have the oxygen we need for our patients ... no more tank oxygen!”

It has been 6 weeks now and we are loving the system! This has been the easiest equipment transition that I have ever been through. The install was both smooth and seamless. My staff and doctors would not have been aware of the transition if we had not told them it was happening. Today we had our oxygen delivery service pick up our 6 tanks for the last time. I cannot say enough good things about this system - no more running out of O2, no more frantic drives to pick up O2 in my car, no more damaged regulators, no worrying about the O2 getting turned off at night- the stress relief is worth the switch alone, but add to the equation that I am actually saving money and I feel like I made the right choice. My lease payment is less than half of what I had been spending on O2 and in a few years, I won’t even have the lease payment. This system is already saving me money. We installed our system in our computer server room, when the system is going full blown - three concentrators and the compressor, it is still quieter than the fans on my servers! I love the modularity of the system - knowing that I can easily replace a concentrator or expand LPM without interrupting the production of O2 makes this system the best I have seen and certainly the easiest to maintain and upgrade. If you ever need an install site to show a perspective client, do not hesitate to call on us - we love to show off our system.

As a busy 7 doctor emergency and critical care practice, we have utilized the HVO 30 Modular Oxygen System with three oxygen concentrators since May of 2014. This system has proven to handle all of our oxygen needs in a safe, efficient and cost effective manner. Obtaining this in-house oxygen generation system was a wise choice for this practice.”
