Air Conditioning

Refrigerant gases are harmful to the environment. VES work with manufacturers to ensure leakage is kept in tolerance. Whether your part contians R134YF or R744 (CO2) VES have a solution to meet your requrements. As it stands VES have machines in operation able to process condensers, heater cores or evaporators in less than 10 secs per part with minimal footprint.


Battery testing to IP67 in avoidance of ingress is essential for safety and efficiency of the electric drivetrain. Literature suggests that IP67 can only be attained through tracer gas leak testing as other methods are unable to reach the required sensitivity. Not only are the battery cells and modules tracer gas tested, but the largest automotive suppliers tracer gas test the battery coolers also.

Fuel Systems

Testng inline with 15 micron, 1mm channel specifications? No problem. VES can help guarantee your components meet the manufacturers specification in the quickest and most helium efficient way possible. At present 30% of all cars in Europe and the USA have a fuel tank fitted which has been through a VES helium leak test system.


The H2Safe product range was developed by VES to accommodate 900 bar testing of hydrogen tanks to ensure no leakage occurs. H2Safe offers a 100% non-operator dependant qualitative test that is safe. Get in touch to find out more.

VES also noticed a poor MSA scoring on traditional pressure decay testing of fuel cells, costing manufacturers thousands of pounds in re-work and re-test fees. We implemented a tracer gas test system to minimise footprint and increase production throughput. Get in touch to find out more.


Quality airspring manufacturers use helium leak test systems. VES have produced many such machines to ensure leakage in the spring is not responsible for the ride height drop of the vehicle. Old hat water bath technology isn’t stable or suitable for quality component manufacture. Get in touch to see how we can help.
