In the evolving landscape of industrial manufacturing, one thing is certain—your operation’s gas demand won’t stay the same forever. Whether you’re in food packaging, aquaculture, electronics, chemical processing, or pharmaceuticals, increased production capacity often brings an increase in nitrogen or oxygen gas requirements. That’s why Canada Gas Solutions has engineered the Field Expandable System (FES) — a scalable and future-ready solution for onsite PSA nitrogen and oxygen gas generation.
WHAT IS THE FIELD EXPANDABLE SYSTEM (FES)?
The FES is a unique, PSA gas generator design that allows customers to expand gas output capacity by simply adding additional adsorber towers to the existing system frame—without having to purchase a completely new standalone system. This innovation is aimed at supporting businesses that anticipate growth but want to avoid redundant investments and system overhauls in the future.
HOW FES SYSTEMS COMPARES TO CONVENTIONAL MODULAR SYSTEMS
Most gas generation systems on the market today are limited in scale or will provide limited scalability. By contrast, Canada Gas Solutions’ FES design allows your system to grow with your operations. Whether you need to double, triple, or even quadruple your system’s flowrate, you can do so seamlessly—by simply integrating new adsorber towers into your existing system frame.
REAL-WORLD COST COMPARISON: FES VS. CONVENTIONAL SYSTEMS
Let’s break it down with an example:
- A twin tower psa nitrogen generator system might cost approximately $47,000 CAD for a medium range flowrate application/project.
- If your production needs to double in two years, buying another unit would bring your total investment to around $94,000 CAD.
Now consider a Field Expandable System:
- The initial cost of an FES unit capable of 2x expansion may be slightly higher—around $50,000 CAD.
- When the time comes to expand, you only need to invest $28,000 CAD to add another set of adsorber towers, make necessary piping modifications, reconfigure the control system, and commission the updated system.
Total cost with FES: $78,000 CAD
Compared to conventional: $94,000 CAD
Not to mention lower installation overhead and zero duplication of controllers & controls, valves, piping or system frames. Note : This is an example for explanation only. Actual savings vary based on system size and application requirements.
DESIGNED FOR OPERATIONAL FREEDOM AND LOWER MAINTENANCE COSTS
Another key advantage of Canada Gas Solutions’ FES design is that it’s built entirely using non-proprietary components. This gives end users the freedom to maintain and service the system themselves, without being tied to a single-source vendor. Parts are widely available, and maintenance can be handled by in-house teams or local service providers—helping to keep long-term maintenance costs as low as possible.
This level of independence and flexibility is rarely found in proprietary modular systems, which often lock customers into expensive service contracts and limited parts availability.
SCALABLE COMPRESSION & ENERGY EFFICIENCY
Designing for future expansion also means planning compressor capacity wisely. FES system performs best when paired with:
- A compressor system with turn-down/turn-up capability to optimize energy usage during varying demand, or
- A scalable approach, where additional compressors can be added in the future as more adsorber towers are integrated.
This ensures the entire system grows efficiently and cost-effectively with your production requirements.
A SMARTER LONG-TERM INVESTMENT
FES systems are designed with the end user’s growth, flexibility, and cost-efficiency in mind. By investing in a scalable system from day one, you avoid unnecessary duplication, reduce capital, and eliminate the logistical headaches of installing entirely new PSA systems down the line.
Whether you’re planning an expansion in 6 months or 3 years, the Field Expandable System by Canada Gas Solutions gives you the flexibility and confidence to grow without overcommitting resources too early.
