When you are manufacturing high-pressure components, the consequences of a leak are measured in safety, not just scrap. Whether you are dealing with HVAC systems, heavy-duty hydraulic assemblies or next-generation automotive parts, those systems have to hold pressure without leaking.
We have always advocated helium for the most demanding leak detection work, and we always will. But argon is an effective tracer gas that bridges the gap between pressure decay and ultra-sensitive helium testing. It is the right choice when air testing is not sensitive enough, but helium goes beyond your actual product specification.
For many manufacturers, that middle tier is exactly right. But what happens when the product has to be tested at extreme pressure?
The 200 Bar Engineering Challenge
Applying argon testing at standard pressures is one thing; taking it to 200 bar is another. At that pressure the behaviour of the gas changes, and operator safety governs every design decision. Testing at 200 bar requires specialised manifolds, high-integrity seals and precise control.
Customers came to us knowing argon suited their testing range, but hesitant to run it at that pressure. We understood why. Developing a high-pressure testing system from scratch involves significant R&D, complex engineering and real risk. You are already managing production, throughput and customer deadlines. You do not have the time, budget or appetite to run high-pressure experiments on your own factory floor.
Doing the Heavy Lifting in Our Own Labs
We do not think a customer should be the test subject for a new process. That is why our engineering team at our headquarters in Sweden took the risk on instead. We set out to validate argon leak testing at 200 bar in our own controlled test environments, so the technology was proven before it reached anyone’s factory.
For our R&D team, that meant designing custom high-pressure tooling, sourcing durable valves and building mechanical fail-safes able to take the repetitive stress of a high-speed production line. We tested the gas behaviour, mapped the compression cycles and verified detection accuracy to confirm the argon system held its sensitivity under pressure.
Turning Experimental into Operational
The validation process wasn’t just
about proving it was scientifically possible in a lab; it was about proving it
was practical for everyday manufacturing. We needed to ensure that your
operators could run these high-pressure argon tests safely, reliably, and
efficiently shift after shift.
By absorbing the trial-and-error phase
ourselves, we worked through the engineering problems before they reached a
customer. We refined the gas recovery process, improved fixture durability and
confirmed measurement accuracy at pressure. We documented every step, and that
became a complete validation package. So when an auditor asks how you know your
200 bar test is safe and accurate, the data and the engineering proof already
exist.
What This Means on Your Factory Floor
So what does this mean for your
production line? It means you get a tested system rather than a prototype. If
your product needs a sensitivity that sits between pressure decay and helium,
and it operates under extreme pressure, you do not have to build a system from
the ground up.
You can integrate a high-pressure
argon system knowing the safety protocols, cycle settings and detection
parameters have already been tested and documented. What you receive is an
automation-ready system with the evidence behind it.
Advancing your quality control should
not mean taking a leap into the unknown. We took the technical risk so you do
not have to. If you are testing at high pressure and want to see the evidence
before you commit, ask us for the 200 bar validation summary.
