Across industries—from food packaging and laser cutting to hospitals, labs, 3D printing, power plants, aquaculture, and beyond—nitrogen or oxygen gas is often the invisible backbone of operations. Traditionally, many facilities meet their gas needs through high-pressure cylinders or bulk cylinder manifolds. While this model has worked for decades, it’s far from efficient, and it may be costing your operation far more than necessary. At Canada Gas Solutions Inc.(CGSI), we help companies understand their gas consumption patterns and transition to on-site nitrogen or oxygen gas generation systems that deliver long-term cost savings, operational efficiency, and sustainability.
THE REALITY OF INDUSTRIAL GAS CYLINDERS
Industrial steel gas cylinders come in a wide range of sizes and pressure rating. The most common cylinder size in industrial settings has a water volume capacity of 49 litres and a working pressure of 150 barg (cylinder volumes & pressure ratings can vary manufacturer to manufacturer). These cylinders typically contain around 7–7.3 cubic meters (247–257 cubic feet) of gas.
When these cylinders are manifolded together—often in groups of 4, 8, 16 or more—they form what’s known as a bulk pack, with 16 cylinders delivering up to approximately 4000 cubic feet of gas at full 150 barg pressure. But this is where inefficiencies start to add up.
Hidden Wastage: Pressure Matters
If your process requires a minimum pressure of, say, 250 psig, you can only use the bulk pack until it drops to that level. The remaining gas—often around 30 cubic feet per cylinder—becomes unusable unless you’re charged based on actual usage which is vary rare. The higher your required process pressure, the greater the wastage.
UNDERSTANDING YOUR TRUE GAS NEEDS
Say you’re using one bulk pack (16 cylinders) every 8 hours—that’s approx. 500 cubic feet per hour (cfh). While this gives you a rough idea of average usage per hour but average flow rates don’t tell the whole story.
To design the right on-site gas generation system, it’s essential to understand:
- Peak Flow Rate
- Duration of Peal Flow Rate
Accurate digital flowmeters can help capture these metrics when installed with a data logging system. Once you know your true process gas needs, we can start designing an on-site gas generation system that replaces your rental bulk packs or cylinders altogether.
TWO APPROACHES TO REPLACING RENTAL BULK PACKS
Depending on your application and daily routine, there are two primary system configurations that can replace rental bulk pack cylinders.
1. Continuous Flow & Pressure System
Ideal when your process needs are at a steady flow of 500 cfh at 250 psig.
Main System Components:
- Screw Air Compressor (air- or water-cooled)
- Refrigerated or Desiccant Air Dryer
- Dry Air Receiver Tank
- Gas Generator (PSA, VPSA, or Membrane)
- Low-Pressure Gas Storage Tank
- Gas Booster Compressor
- High-Pressure Gas Storage Tank
2. Bulk Pack Charging System
Idea when gas flowrates are not steady. This system runs at night to fill cylinders or manifolds that you own as part of the on-site gas generation system for use during daytime operations.
Main System Components:
- Screw Air Compressor (air- or water-cooled)
- Refrigerated or Desiccant Air Dryer
- Dry Air Receiver Tank
- Gas Generator (PSA, VPSA, or Membrane)
- Low-Pressure Gas Storage Tank
- Gas Booster Compressor sized for desired fill rate
- Cylinder Manifold (Sized based on required gas storage capacityto meet your process gas flow needs)
WHY MAKE THE SWITCH?
- Cost Savings: Most companies recoup the cost of their system in 6–24 months.
- No More Deliveries: Eliminate dependence on scheduled deliveries and cylinder handling.
- Reduced Wastage: On-site systems deliver gas at the pressure you need—without leftover gas.
- Operational Uptime: Say goodbye to downtime due to late deliveries or empty cylinders.
- Sustainability: Reduce your carbon footprint by eliminating transport-related emissions.
CANADA GAS SOLUTIONS: YOUR PARTNER IN THE TRANSITION
We provide turnkey solutions tailored to your needs. Whether you want a complete system or just a component—like an on-site gas generator, gas booster compressor, high pressure cylinder manifold, low-pressure & high-pressure gas storage tanks—we can supply any piece of the puzzle.
Already have an on-site nitrogen or oxygen system? We can help upgrade your low-pressure setup to a high-pressure cylinder charging system to meet new or growing gas demand—without replacing your existing investment. Consult your options with CGSI.
If you’re still renting cylinders or coordinating bulk pack deliveries, it’s time to ask: How much is this costing me? Connect with Canada Gas Solutions today for a consultation. We’ll evaluate your current gas usage, show you how to transition, and help you build a system that fits both your technical needs and your budget.
