Vapor Recovery

For decades, VRUs have been deployed as compliance equipment and treated as commodity hardware – sized on rough estimates, lightly engineered, and minimally monitored. The results have been predictable: inconsistent runtime, chronic loading instability, ever-increasing maintenance costs, and a long-standing belief that VRUs simply “don’t work.” This paper examines why that legacy persists and outlines a modern engineering and measurement framework that significantly changes VRU performance, economics, and reliability.
