Custom Vacuum Chambers That Actually Fit Your Process – Here’s What We Can Build For You

I’ve said it before, but it’s worth repeating: nobody’s real-world application matches a generic catalog chamber. That’s why at Chendun, we stopped trying to fit customers into boxes – literally. Instead, we build custom vacuum chambers, complete with the right pump, the right plumbing, and the right little details that make your process actually work.

Let me walk you through what we can do. Not theoretical – stuff we’ve already delivered.

First, we handle the whole package – chamber, pump, and all plumbing

Some companies sell you a bare chamber and say “good luck.” We don’t. We’ll supply the vacuum pump (rotary vane, dry screw, Roots, whatever your application needs) and all the connecting lines, valves, and fittings. No chasing down missing adapters at 4 PM on a Friday.

More importantly, we’ll recommend the right material and vacuum level based on what you’re actually doing. Not over-specced to jack up the price, not under-specced to win the bid and leave you stuck.

Four material choices – including fully tempered glass

We don’t believe in one material for everything. Here’s what we offer:

• Acrylic (Plexiglass) vacuum chambers – Perfect for low vacuum (down to around 10 Torr), especially when you need to see inside. No corrosion worries. Lightweight. Great for classroom demos, food packaging tests, or anyone who just wants to watch the process.
• Mild steel / carbon steel chambers – Strong, affordable, and we can coat or plate the inside for corrosion resistance. Good for medium vacuum and industrial environments where stainless is overkill.
• Stainless steel chambers (304 and 316) – This is our workhorse. 304 for clean, dry applications. 316 when you have moisture, acids, or aggressive chemicals. We can electropolish the inside for high vacuum or leave it as-welded for rough vacuum work.
• Fully tempered glass chambers – Need to watch a reaction or a degassing process under vacuum with no optical distortion? Tempered glass is tough, clear, and safe. We can build square, rectangular, or cylindrical glass chambers with sealed edges and vacuum-rated ports.

You tell us your vacuum pressure requirement – down to 10⁻⁶ Torr or just 200 Torr – and we’ll pick the right material and wall thickness. Simple.

Any shape you need – really, any shape

Round, square, rectangular, hexagonal, domed, stepped, or something completely odd. We can customize the shape of the vacuum chamber or sealed box to fit your product, your production line, or your space constraints. Don’t let a standard cylinder force you to redesign your test. Tell us the dimensions and shape you want – we’ll build it.

Custom ports, KF fittings, and electrical feedthroughs – no more kludges

Ever tried to add a sensor to a chamber that has only one useless port? Frustrating. We start by asking: what needs to go in or out of your chamber?

• KF (quick-flange) fittings in any size – 16, 25, 40, 50. You want them on the lid, on the side, on the back? Done.
• Electrical feedthroughs – power cables for heaters, signal wires for thermocouples, even coaxial for RF. We use ceramic-sealed, vacuum-rated connectors so you can power and monitor your sample without breaking vacuum.
• Extra ports for future use – because we know your process will evolve.

We recently built a chamber for a battery tester that needed twelve individual wires going in. Twelve. We made a custom multi-pin feedthrough flange. No leaks, no hassle.

Temperature and humidity control – inside the vacuum

Yes, you can have both. We add heating elements (mica heaters, silicone mats, or cartridge heaters depending on temperature range) and temperature controllers with PID tuning. For cooling, we can run chilled fluid through internal coils or use Peltier modules for smaller chambers.

Humidity is trickier, but we have a solution: a controlled water vapor injection system with a heated line. We’ve done everything from 20% RH to 95% RH under reduced pressure. Just tell us your target – e.g., “85°C / 85% RH at 50 Torr” – and we’ll size the vapor generator.

Atmosphere control – purge or fill with any gas

Sometimes vacuum isn’t the end goal – it’s the means to remove air so you can backfill with something else. Argon, nitrogen, helium, even reactive gases. Our chambers come with gas inlet and purge valves, plus a vent port. You can cycle between vacuum and gas fill as many times as needed.

We’ve built “atmosphere chambers” for customers who want a controlled environment at sub-atmospheric pressure – like 500 Torr of nitrogen with 5% hydrogen. No problem.

Shelves and perforated trays – because your sample needs to sit somewhere

Standard chambers often come with one fixed shelf. That’s rarely enough. We’ll build custom shelves – multiple levels, removable, with or without holes.

Speaking of holes: we can perforate the shelves (openings of any size and pattern) so that vacuum reaches your sample from all sides. This is critical for drying powders, degassing foams, or testing circuit boards where every surface matters.

And yes, some customers use the holes to mount vacuum pressure gauges or other electrical components directly onto the shelf. We’ll add threaded inserts or pass-through holes exactly where you need them.

Vacuum degassing equipment – tailored to your material

This is our specialty. Whether you’re degassing epoxy resin, silicone rubber, transformer oil, or food slurry, we can build a custom vacuum degassing system.

What does “custom” mean here? It means we ask:

• What’s your material? (Viscosity? Contains solvents? Abrasive?)
• What’s your batch size? (500 mL or 500 liters?)
• Do you need heating during degassing?
• Do you want continuous flow or batch processing?

Then we design the chamber size, the pump capacity, the stirring mechanism (if needed), and the fill/discharge ports. We’ve done small benchtop units for jewelry casting and huge tanks for industrial epoxy – the same principles, scaled up.

Why we can do all this – and why it’s better

Here’s the honest truth: we’re based in China, and we use the full industrial supply chain here. That means we get raw steel, glass, pumps, fittings, sensors, and controllers fast and affordably. That savings goes to you. We’re not reinventing the wheel – we’re assembling the best wheels at a fair price.

We’ve reached a point where our vacuum chambers and complete systems are genuinely leading in the industry. Not because of magic, but because we listen, we customize, and we test before shipping.

Choose Chendun – we both win

We’re not trying to be the biggest. We’re trying to be the most helpful. When you work with us, you get a chamber that fits your process, not the other way around. You get a partner who answers the phone when something weird happens.

That’s the “win-win.” Your application works. Our reputation grows.

So whether you need a simple acrylic box with a KF fitting and a humidity probe – or a fully tempered glass chamber in a custom hexagon shape with heated shelves and gas backfill – reach out. Tell us your messy details. We’ll build exactly what you described, and probably a few things you forgot to mention.
