Closed Loop Sampling System

Wanan Sample Cylinder is widely used on petroleum device, chemical device and so on, especially leak-proof sampling for toxic, harmful, flammable, explosive and some other dangerous gas or liquid with medium or low pressure, like residual oil hydrotreating unit, heavy oil catalytic cracking unit, gas fractionation unit and so on. Sample collected by Wanan sample cylinder is authentic, accurate, no residual liquid, no residual gas emissions, protecting operators from harmful media, meanwhile no harm to environment, and eliminating accident from flammable, explosive median during sampling.
