Precision gas mixing should not require expensive pre-blended cylinders or inflexible hardware. At Pneucleus, we offer the tools you need to mix gases correctly and in real time – right at the point of usage.
Our mass flow controllers, offer 40ms response times, customer specified control ranges, and easy software integration. Whether you’re working on fuel cells, fine-tuning laser systems, or scaling up industrial processes, Pneucleus systems stabilize faster, use less gas, and will give you complete control over each blend.
Mix what you need, when you need it, without compromise.
Conventional gas mixing systems impose unnecessary limits, both operationally and economically. Most configurations suffer from the following:
- Slow stabilization, wasting gas during ramp-up, and increasing process time.
- Pre-mixed gas cylinders are expensive, provide only fixed ratios and incur ongoing supply costs.
- Narrow flow ranges make it impractical & difficult to achieve ppm-level traces within bulk flows using the same equipment.
- The lack of traceability complicates compliance and affects process consistency.
From laser systems requiring ppm-level control to hydrogen fuel cell modelling, typical gas mixing wastes gas, produces inconsistent results, and reduces productivity.
We create gas mixing systems that adapt to your process, not the other way around. Whether you’re adjusting ppm-level traces or balancing large flows, our equipment is designed to provide quick, precise, and repeatable process control.
Dynamic Range
Mix everything from fractional parts per million to liters per minute on a single platform. Turndown ratios of 100:1 allow you to blend trace and carrier gases without changing hardware.
Fast Stabilization
Our InSitu-Sense™ sensors monitor flow directly in the gas stream, providing closed-loop feedback with milli-second reaction times. This implies faster blend lock-in and less wasted fuel.
Smooth Valve Control
Tri-Planar™ valves reduce overshoot and pressure transients over a wide range of settings. The end effect is consistent delivery, even during fast ramping or low-flow mixing.
Digital Integration
Complete control via serial-addressable communication allows up to 99 mass flow controllers to be on the same bus. Automate sequences, monitor blend composition in real time, and record each cycle for traceability and compliance.
Our Manifold-Mount gas mixing systems are intended for precision-critical applications where speed, repeatability, and control are required. Here’s how we improve outcomes across industries:
- Fuel cells – Mix hydrogen/nitrogen blends dynamically to simulate real-world situations. Pneucleus controllers allow you to adjust ratios in real time to speed up modelling, improve reaction efficiency, and reduce hydrogen waste during process cycles.
- Laser gases – Maintain consistent ppm levels with dopants such as halogens, CO₂, or rare gases. Fast stabilization and a 100:1 turndown ratio decrease overshoot, protect optics, and reduce gas consumption during warm-up and during process runtime.
- Environmental Simulation – Reproduce atmospheric mixes with accuracy, regardless of environmental influences or material responses, Pneucleus systems offer traceable, reproducible gas delivery under changing conditions.
- Biotech and Fermentation – Mix O₂, CO₂, and N₂ on demand for cellular development or metabolic adjustment. Our multi-channel systems offer precise, real-time gas control, which saves gas and ensures culture viability.
If you’re building a next-generation fuel cell or a high-throughput environmental simulation system, Pneucleus has or can easily create scalable hardware configurations to meet your flow, blend, and integration requirements.
