Avoiding the CRN Requirement for Venturi Eductors and Ejectors

 

Fox Venturi Ejectors for Hydrogen, Natural Gas, Steam Applications in Fuel Cells

Evacuating or Purging Vessels, Tanks, and Pipelines: Engineered for operation in Canada to avoid CRN and enable fast shipment

Evacuating, Purging, and Exhausting Vessels, Tanks and Pipelines with Venturi Ejectors that do NOT require a CRN.

Venturi jet ejectors that use a motive gas pressure below 14 psig are exempt from CRN requirements. This enables Fox Valve to deliver quickly modified venturi gas ejectors – using air, N2, CO2, nat gas, etc. at 14 psig or below. Stock venturi components in line sizes from 1/2 to 6 inch, in carbon steel and 304 or 316 stainless, can be modified in this way. This eliminates the CRN requirement and enables venturi delivery to proceed quickly.

Limitations: Operation with motive gas at below 14 psig limits: a) the final vacuum that can be created – approx. 10 – 14.7 psia, or b) the discharge pressure that can be overcome. For exhausting, venting or purging corrosive, explosive or high-temperature gasses – this approach enables Canadian customers to acquire customized gas jet ejectors that can ship, in many cases, in 1 – 2 weeks.
