Welker Constant Pressure Cylinder & Sampling Cylinders

CAC GAS Asia is a distributor of a range of Welker products including Constant Pressure Cylinders, Sampling Regulators, Valves & Probes, Sample Cylinders, Sampling Systems, and Carrying Cases.

The Constant Pressure Cylinder, designed with an internal piston and seals, the CP2 cylinder is pressured with an inert gas supply, and then turned around and filled slowly from the opposite end. By letting the gas push against the piston, slowly venting the pre-charge gas, the sample is taken at full line pressure from start to finish. While the cylinder is being emptied, full pressure is being maintained and the gas composition is not being altered as a result of pressure reduction. The cylinder is equipped with valves, safety reliefs, and gauges on both ends and thus the pressure can be controlled and monitored at all times on both ends.

At Welker, quality and craftsmanship in both construction and design are most important. All of their constant pressure cylinders are designed with a standard 4-to-1 safety factor, unequaled in the industry. Constructed of 316 SS and honed to 2-4rms, Welker® CP2 cylinders give years of dependable service and quality results.
