Chris Styles and Alan Hopkins, co-founders

In 2017, Chris Styles and Alan Hopkins left their senior management roles in the industrial energy efficiency sector to launch Purity Gas, Inc. — the first company in Canada with a dedicated focus on modular, high efficiency nitrogen gas generation systems.

The duo has received numerous industry awards and accolades for their work in conserving electricity in compressed gas systems within industrial facilities. Passionate about client education and the impact of nitrogen generation system design on electrical requirements, Chris and Alan are committed to continuously pushing the boundaries to create environmentally and economically sustainable solutions.


What we do — It’s client focused.

Purity Gas empowers nitrogen users to produce and store their own supply of high purity nitrogen gas, safely and efficiently. Our custom NITROCENTER® technology solutions typically save our clients 90% over traditional supply sources.

We serve clients in industries ranging from metal fabrication and processing to food and beverage production. Our solutions are engineered for applications like laser cutting, packaging, blanketing and virtually any application that requires nitrogen.


Why we do it — It’s the driving force.

Purity Gas was founded to challenge the aging and stagnant gas supply industry, where a decades-long lack of competition has led to complacency in innovation, cost competitiveness and customer service.

At Purity Gas, we’re invested in our clients’ success, contributing to their financial and operational goals. Our projects create local jobs and economic prosperity because our clients are hiring more staff, increasing production volume and scaling their businesses.
