Helping the industry move forward starts with sharing what we know. Our team recently spent the day at NWTC College of Advanced Manufacturing & Skilled Trades, putting our natural gas products to work under real-world conditions while filming a new series of how-to videos for utility professionals.

We also had the opportunity to work alongside NWTC’s Gas Utility students—sharing what we know, giving hands-on experience, and talking through the ins and outs of the products and applications they’ll encounter in the field.

It was a great opportunity to connect with the next generation of gas utility professionals who inspire us every day, while creating a practical resource that operators can use to see our products in action and brush up on key applications.

A big thank you to NWTC for the continued partnership and another great day of collaboration and hands-on learning! 👏
