Rusty Frishmuth shows off an air compressor powering controllers at an oil field off Hwy. 34 east of Greeley, Colo., on Feb. 24, 2021. Controllers at this facility are powered by compressed air.
Rusty Frishmuth opened a metal equipment cabinet in an oil field east of Greeley and waited for the sound.
A few minutes later, a sharp
woosh blew from inside. It was the sound of a pneumatic controller in action.
“Incredibly exciting, right?” joked Frishmuth.
As the director of environmental health and safety for HighPoint Resources, which drills across the Denver-Julesburg Basin, he’s used to hearing these little devices throughout the day.
