Engineered for automotive HVAC and EV components, the Sleek HLT delivers repeatable, audit-ready precision backed by local service and rapid response across the U.S.
VES Sleek HLT is the next-generation helium leak testing system for automotive HVAC and EV components such as battery cooling plates, condensers, evaporators, and e-compressors.
Built for demanding production environments, Sleek HLT delivers audit-ready accuracy, faster test cycles, and optimized helium use all without unnecessary complexity.
Detects leaks as small as 1.00E-10 mbar∙L/s, ensuring every part meets.
Certified under OSHA & CE Mark, SLEEK HLT protects operators while maintaining full production speed.
Designed for automotive HVAC and EV manufacturing, the SLEEK HLT provides measurable improvements in precision, uptime, and efficiency.
SLEEK HLT optimizes vacuum, purge, and fill sequences through advanced valve control cutting total cycle time by up to 20%.
This means more tested components per shift and faster line throughput, all without increasing footprint or sacrificing precision.
SLEEK HLT’s modular single or twin-chamber layout adapts to any production environment.
It can easily integrate with robotic handling systems and automation lines, giving you the flexibility to scale capacity or reconfigure as product designs evolve.
With VES Connect, operators have real-time visibility into cycle times, leak rates, and equipment health.
Smart alarms and KPI dashboards detect deviations early, reducing false rejects and downtime while providing full traceability for audits.
This digital visibility turns helium leak testing into a predictable, repeatable process aligned with ISO and IATF quality standards.
Supported by VES teams in the U.S., Mexico, and U.K., Sleek HLT ensures local expertise, rapid service, and spare-part availability.
This reduces downtime, eliminates delays from overseas support, and keeps production continuous across shifts.
Every Sleek HLT can be customized with VES Add-Ons modular upgrades that adapt to your plant’s operational and safety requirements.
These configurable options enhance performance, maintenance, and automation integration.
Safety: Perimeter guards, light curtains, door interlocks, and acoustic insulation ensure zero-incident operation without slowing production.
Maintenance: Predictive alarms, quick-swap modules, and annual service plans reduce MTTR and maintain stable uptime.
Traceability: Barcode/QR reading, MES/ERP integration, and automatic audit reports enable defensible test records and faster approvals.
Helium Recovery: It reduces helium use by up to 45%, maintains stable background pressure, and delivers audit-ready results with lower operating costs and a faster ROI.
Automation: Dual stations, robotic loading, and poke-yoke conveyors boost throughput and consistency.
Sleek HLT ensures leak-free coils, condensers, and EV cooling plates through stable, repeatable helium testing even under heavy production shifts.
Every part passes. Every audit, cleared.
With optimized vacuum and fill control, Sleek HLT completes each test faster helping you meet production targets without expanding your floor space.
More tests. Same footprint.
VES Connect gives you full visibility live KPIs, automatic reports, and predictive alerts.
Stay compliant. Stay in control.
With service teams and spare parts available across the U.S., Mexico, and U.K., VES keeps your production running.
No delays. No overseas waiting.
With the Helium Recovery and Gas Mixer Add-On, Sleek HLT cuts gas consumption by up to 45% per test cycle while maintaining precise, repeatable results.
A smart upgrade that pays for itself in months.
Add automation, helium recovery, or traceability modules as you grow without redesigning your line.
Your system evolves with your business.
