Qnergy CAP3F CAP3M and CAP3L from OilPro

Increasingly, governments around the world require oil & gas companies reduce their methane emissions and lessen their overall carbon footprint.

The Canadian government gives incentives to oil & gas producers to reduce their emissions with initiatives like the Emissions Reduction Fund – Onshore Program. It’s not too late to take part in this program but you should act quick so you don’t miss out. You can contact OilPro directly to learn more about how to take advantage of this program with a number of application we’re implementing with our clients.

Introducing Compressed Air Pneumatics (CAP3)

This is the first 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 first article we’ll focus on the CAP3-F Walk-in Shelter with auxiliary equipment space. We have less-expensive models such as similar performance, external access-M and higher electrical output, smaller air output Nano models available also.

The Compressed Air Pneumatics product line first came to light when OilPro profiled it at the Global Energy Show in 2019.  The product evelved significantly since as you now have three product lines to choose from. Let’s focus on the CAP3F for this article.

Why choose CAP3-F for your remote power needs?

Why would you consider CAP3F over the other two options, CAP3M and CAP3Nano? 

Here are the highlight benefits of CAP3F:

  • Fully housed and skidded walk-in enclosure
  • Skid edge availability of 11 SCFM of clean dry air
  • Minimum guaranteed power availability of 1,000W with more when compressor is not running
  • On-board remote monitoring tied to phone, tablet or desktop
  • Air metering for simple carbon credit reporting
  • 3 year warranty on engine
  • HMI panel for quick control and in-building monitoring
  • On-skid battery capacity can be adjusted for client preference
  • -40 C capability built-in
  • On-skid GHT (Glycol Heat Tracing) capability available
  • Can burn propane or any wellhead gas (with up to 1,000 ppm H2S content)

Here are the specifics.
