With the industry using a mix of water cooling and refringent cooling, VES have designed and manufactured a leak detection machine to test both water cooled and refringent cooled loops. Both need leak testing to prevent product failure. With water cooling circuits leak tested to a range of 1e-2 to 1e-3 mbar.l/sec and refringent cooling circuits tested down to approximately 1e-5 mbar.l/sec. All products need testing to comply with IP67. VES has experience in testing to all products to meet IP67, with our accumulation machines testing to 1e-3 mbar.l/sec.
VES are the only manufacturer of leak testing equipment to have designed and built a machine running multiple gases on different circuits simultaneously. Maintaining product reliability while continuing to achieve a short cycle time.
Vacuum Engineering Services can design and manufacture leak detection machines for all applications including cooling/heating plates and battery coolers of different sizes and shapes.
Depending on the leak rate, there are two main methods of testing battery thermal management systems…
