CNG dispensers are the primary interface between a CNG station and the fueling customer. As such, considerations such as design, reliability, performance and safety are vitally important to station owners.
At Kraus Global, we understand that CNG dispenser performance and reliability play a critical role in station "up time". With 3,500 CNG dispensers installed in over 30 countries, we have experience with just about anything that can affect a CNG dispensing unit's reliability and performance - from intense heat and humidity to sub-zero temperatures, inconsistent power supply, poor gas quality, and severe usage. This has enabled us to design CNG dispensing systems that consistently withstand extreme
conditions with ease. Our CNG dispensers also come equipped with full flow safety relief valves as well as excess fill and flow safety shutdowns, showcasing our commitment to safety and allowing us to obtain the most approvals of any CNG dispenser on the market.
Kraus Global - CNG dispensers done right.
