VSS 15 Mobile vacuum suction system for extrem sensitive gas detection. What is the current situation? As we know, the process of detecting gas leaks is as follows: The gas enters the soil and spreads there. Diffusion processes and the different densities of the soil air and gas cause the gas to finally rise to the surface of the ground. Sealed or wet surfaces are more difficult for the gas to pass through. Leaks can only be localized if the gas rises to the surface of the ground „voluntarily“ and in sufficient quantities. And this is where vacuum technology helps. Before the gas reaches the surface, it has collected in the ground and lies there as if absorbed by a sponge in higher concentrations than on the surface of the ground. To get meaningful indications on the gas detector even in particularly difficult situations, these cushions of gas are vacuumed. Bell probe

How does vacuum technology work? A vacuum pump with a suitable suction system is used here. The important thing is to coordinate the suction and vacuum power and to achieve a seal with the ground to prevent unwanted dilution of the gas sample. Just a small partial flow from the extracted gas sample, but with a high concentration of gas, is made available to the gas detector for analysis. How much does it really help? Firstly, it saves time. Imagine using gas detectors in the tracer gas method and receiving the results hours earlier with cohesive soil, a wet ground and compacted surface. And...
