Pressure Reducing Systems

Bison Pressure Reducing Systems / Units, PRS / PRU, for Industrial Gas and CNG Virtual Pipeline are designed to maximise gas delivery per load, increase operating efficiency, improve reliability and reduce maintenance costs.

Made in New Zealand, our team have been manufacturing Pressure Reducing Systems since 1984. We understand the complexities and requirements to manufacture a reliable unit.

Maximum Gas Delivery
Engineered for optimal flow end-to-end, Bison Pressure Reducing Units will extract as much gas as possible from a tube trailer / mobile gas storage unit. Component selection and sizing is critical to ensure operators get the most from their equipment. Improve usable payloads by up to 10%

Reduced Maintenance
Our electric boiler models do not require pumps to circulate water within the system. This eliminates water pump issues, piping issues, vessels and remote storage tanks.  Our decant systems and regulator setups are designed to reduce pulsations, improving regulator life.

Energy Efficient
Using convection instead of pumps for water circulation allows the gas heating system to be simple, efficient, compact and well-insulated. It also eliminates on-site water piping and recirculation pumps common with other systems.

Redundancy for Reliability
Dual regulator lines and automatic fault-sensing gives operators peace of mind that the system will keep running 24/7. Our algorithm senses if a regulator needs servicing and will automatically switch to the other line and alert the operator.

Return on Investment
With more gas delivered per trailer, less maintenance and lower operating costs, Bison equipment is an excellent choice for virtual pipeline operators looking to make the most of their investment.
