When you are walking the floor of a high-throughput production plant, it is rare to see an environment built around a single brand of machinery. Over years of scaling up, whether you are processing HVAC coils, automotive climate control loops, or clean energy fuel cells, facilities naturally accumulate a mixed-vendor fleet of leak testing benches. You might have a high-end customised vacuum rig on Line 1, a different manufacturer’s standard platform on Line 2, and a legacy tester on Line 3.

Historically, this layout diversity made any site-wide efficiency upgrade a monumental chore.

Traditional recovery loops require deep, machine-specific integration. They demand custom logic handshakes, complex PLC code rewrites, and invasive line shutdowns just to get the hardware to communicate with each different tester brand on your floor.

The solution requires moving away from complex software integration entirely, shifting instead to a completely autonomous, brand-agnostic hardware model.

The Mixed-Fleet Integration Trap

For any process engineer, messing with an automated routine that is already validated and running repeatable cycles is a massive risk. When you try to force a conventional competitor reclaim system onto a mixed floor, you hit several distinct roadblocks:

  • The Software Bottleneck: Every tester brand uses a different control architecture. Standardising recovery means your programming team has to write, test, and maintain entirely separate variations of PLC code for every distinct machine on the floor.
  • The Uptime Sacrifice: Code rewrites and validation testing cannot happen while the line is live. You are forced to accept multi-day shutdowns and lost throughput just to tie the hardware together.
  • The Re-Qualification Trap: In highly regulated industries like automotive powertrain or aerospace manufacturing, altering an established machine parameter can trigger extensive, mandatory process revalidation.

When procurement demands immediate insulation from global gas shortages, a slow, invasive development cycle that stalls your lines completely defeats the purpose.

Autonomous Hardware

At Vacuum Engineering Services (VES), we redesigned the mechanics of gas reclaim to completely eliminate this software dependency. PURE functions with complete plug-and-play autonomy.

PURE operates as a self-contained “black box” that requires absolutely no physical signal wiring, electronic handshakes, or PLC communication with your existing leak testing machines. It functions purely as a pneumatic loop: it captures the exhausted gas from your machine’s low-pressure exhaust, purifies it independently, and returns specification-grade gas back to the input side at the exact required pressure.

Because the system is completely separated from the tester’s control software, PURE is entirely brand-agnostic. It connects seamlessly to any helium leak test machine operating under 3 bar without changing your pre-evacuation levels, cycle parameters, or validated cycle times. You can retrofit advanced recovery onto a legacy machine from any vendor in a matter of hours, keeping your factory uptime completely intact.

Shifting Assets to Match Floor Space and Demand Fluctuations

Eliminating the integration bottleneck unlocks a massive operational benefit: true asset mobility. Legacy plants are tightly packed, and dropping a massive, stationary recovery tank beside every single assembly cell is rarely physically possible.

Because PURE features a compact, low-profile design, it can be tucked easily into tight spaces adjacent to your existing rigs without requiring layout modifications. More importantly, because it is software-independent, it is highly transferable.

If Production Line A is throttled down for a model changeover, you can easily disconnect the PURE unit and roll it over to support Production Line B’s upcoming peak shift. This mobility maximises your capital efficiency, allowing a single asset to protect multiple production cells from commodity market price volatility.

Uncompromising Purity and Verifiable Traceability

When you share a mobile recovery loop across multiple machines, your quality team will rightfully demand proof that the recycled gas isn’t diluting. Generic “capture-and-pump” systems frequently suffer from gas degradation because air and nitrogen inevitably bleed into the collection pipelines under real-world factory conditions.

PURE handles this challenge through advanced mechanical separation technology. It actively separates contaminants and re-concentrates the helium back to a guaranteed steady-state purity of over 99% without requiring fresh gas top-ups. Your leak testing process maintains a reliable Cpk greater than 1.67, eliminating the risk of false passes entirely.

Taking the Friction Out of Fleet Optimisation

Upgrading your plant’s gas efficiency shouldn’t mean accepting a wave of custom software integration headaches, multi-day line shutdowns, or rigid vendor lock-in. By separating the hardware loop from the machine’s primary control logic, you can slash your plant’s helium consumption by over 86%, secure a financial payback of 12 to 18 months, and fulfil corporate ESG mandates across your entire fleet.
