Cylinders, Microbulk, or Bulk? How to Choose the Right Gas Storage Method

Posted on: July 10, 2025

When it comes to storing and delivering industrial or specialty gases, the right gas storage system can improve safety, streamline production, and reduce long-term costs. But that system isn’t the same for every operation.

At ILMO, we work closely with ops teams, engineers, and plant managers across Illinois to help them select the most efficient and cost-effective storage option based on how they use gas, not just how much.

In this article, we’ll walk you through the key differences between cylinders, microbulk, and bulk gas storage methods, and offer expert insights to help you decide which is best for your operation.

Pros and Cons of Storing Gas in Cylinders

Cylinders are the traditional go-to for lower-volume needs, variable demand, higher delivery pressure, or limited space. They’re a practical choice for shops and facilities that require flexibility and ease of access without the need for fixed infrastructure. For example, a welding shop that needs to move equipment around the floor frequently may find that cylinders provide the most efficiency.

Advantages of Cylinder Storage:

• Minimal setup, no specialized infrastructure required
• Easy to swap or move between locations
• Ideal for varied or infrequent usage

Disadvantages of Cylinder Storage:

• Frequent handling and change-outs may be required
• Safety risks of frequent cylinder handling
• Risk of downtime if cylinders run empty unexpectedly
• Manual inventory tracking and risk of cylinder loss

How can you tell if you’ve outgrown cylinder storage? When change-outs begin interrupting production, you’re seeking a lower cost per unit on gas product, or lost cylinders start adding up, it’s worth exploring other options. Safety is another great reason to explore microbulk or bulk storage—every cylinder change-out comes with risk, and these larger storage systems help eliminate it.

Advantages of Microbulk Gas Storage

Microbulk systems serve customers with steady, mid-range usage who want to reduce manual labor, improve gas tracking, and gain more control over their supply.

Where microbulk fits:

• You’re using enough gas that cylinders are a hassle
• You want fewer deliveries and improved uptime
• You don’t use enough product to justify a full bulk tank installation

Benefits of Microbulk Gas Storage:

• On-site fill canisters reduce change-outs and eliminate cylinder rental fees
• Safer environment for teams (no cylinder change-outs necessary)
• Better inventory tracking with optional telemetry
• Less residual gas waste and more precise usage data

Many customers are surprised to learn that microbulk is available at their scale. It’s a highly efficient solution that often delivers lower total cost of ownership compared to both cylinders and bulk—without requiring a significant footprint or infrastructure overhaul.

Pros and Cons of Bulk Gas Storage Systems

For large operations with continuous gas use, such as hospitals, food processors, or high-throughput manufacturing, bulk storage is a clear winner in value, efficiency, and convenience. These systems are engineered to handle large volumes with maximum automation and minimal touchpoints.

When bulk makes sense:

• Gas consumption is high and steady
• Uninterrupted supply is business-critical
• You want to eliminate handling altogether

Benefits of Bulk Storage:

• Achieves the lowest unit cost over time on your gas product
• Safer environment for teams (no cylinder change-outs necessary)
• Integrated delivery with scheduled fills
• Compatibility with automated systems and monitors

Possible Disadvantages of Bulk Storage :

• Requires specialized infrastructure, and oftentimes, longer installation lead times
• Longer contracts are usually required
• Risk of product waste with low or variable usage
• Less flexible if needs change
• Refill schedules may prioritize supplier logistics over yours

For high-volume gas users with continuous demand, nothing beats bulk gas storage in safety, efficiency, and value. But while bulk tanks make logistics easier for suppliers and look cost-effective on paper, they aren’t ideal for every customer’s needs. If your operation experiences fluctuating usage or requires infrequent product refills, you could be wasting enough product to cancel out the up-front cost-per-unit benefits. Our experts can help you make the right decision that gets you the most value for your money and keeps you up and running at all times with the proper gas supply.

Ultimately, we believe the system should match the operation, not the other way around. We’ve helped customers scale up to bulk when it made sense, and we’ve helped others downsize from oversized systems that weren’t delivering value.

Choosing the Right Fit: What to Consider

To determine the best storage system, we start by asking a few essential questions:

• What is your weekly/monthly gas usage?
• Is usage steady, seasonal, or highly variable?
• What are the operational risks of running out?
• Are cylinder fees, change-outs, or delivery schedules impacting productivity?
• Would real-time usage tracking or automated reordering improve your efficiency?
• What are your delivery pressure needs? 

With those answers, we can build a storage strategy tailored to your operation.
