In our last article we discussed the CAP3-F remote power configuration in detail. In this article we’ll focus on the CAP3-M configuration and why you might consider it for your remote power needs.
Introducing Compressed Air Pneumatics (CAP3)
This is the second in a series of three articles discussing the Qnergy Compressed Air Pneumatics (CAP3) remote power solution distributed by OilPro across Canada.
We’ll discuss all three solutions to consider. In this second article we’ll focus on the CAP3-M. It’s a less-expensive model with similar performance as the CAP3-F Walk-in Shelter with auxiliary equipment space and the higher electrical output. The smaller air output Nano CAP3 model is also available which we’ll discuss next in the third and final article on CAP3 configurations.
The Compressed Air Pneumatics product line first came to light when OilPro profiled its prototype at the Global Energy Show in 2019. The product evolved significantly since as you now have three product lines to choose from which now include HMI’s and world class integrated SCADA integration and monitoring of genset and air systems.
Let’s focus on the CAP3-M for this article and why you might choose it over the CAP3-F and CAP3-Nano options.
Why choose CAP3-M for your remote power needs?
- Same performance as F-model but in reach-in enclosure
- Lower cost due to reduced enclosure size and no personnel entry requirements such as LEL and gas detection
- Site design can accommodate items like custom RTU’s etc. in other available enclosures.
- GHT option available

Summary
The federal government in Canada gives oil & gas firms incentives to reduce emissions with initiatives like the Emissions Reduction Fund – Onshore Program. CAP3 instrument air systems are an excellent solution.
