We manufacture, send, install, and train your team ensuring rapid ROI and minimal disruption.
Detects leaks as small as 1.00E-10 mbar∙L/s using advanced helium vacuum technology. Every test is stable, repeatable, and OEM-audit ready ensuring no defective parts leave your line.
Optimized evacuation, purge, and fill sequences reduce cycle times by up to 20%. Achieve higher throughput and shorter lead times without expanding your production footprint.
An integrated helium recovery and gas-mixing system (He + N₂) reduces helium usage by up to 45%. Cut operating costs while maintaining top-tier detection sensitivity.
PLC/MES connectivity and the VESConnect platform provide real-time KPIs, alarms, and test traceability by part. Make faster, data-driven decisions and simplify IATF and OEM audit compliance.
Predictive diagnostics and local engineering support (U.S., MX, UK) ensure quick service and rapid spare-part delivery. Reduce maintenance time, lower MTTR, and keep your line running continuously.
The modular single/twin chamber architecture adapts to new product variants and volume increases. Expand capacity or reconfigure easily no redesigns, no over-engineering.




Battery cooling plates, e-compressors, evaporators, condensers, HVAC heat exchangers, and other sealed systems.
Yes the Sleek HLT systems are designed under CE/OSHA/ISO 12100 and IATF 16949 frameworks.
Sure can. We have designed more than 1,500 systems across multiple industries allowing us to understand different levels of leak tightness. We have also mathematical ways of converting refrigerant weight loss per year into quantifiable leak rate values used in our systems.
It detects micro-leaks as small as 1.00E-10 mbar∙L/s, meeting and exceeding OEM and IATF standards.
Engineered and built by VES Mexico, supported by teams in the U.S. and U.K.
Through gas mixing and recovery optimization, reducing net helium usage by up to 20%.
