The Real Cost of Conveyor Components: Why Interroll’s Modular Platform Lowers Your TCO

Interroll’s modular conveyor platform will save you money—not just on parts, but on installation, maintenance, and energy over the system’s lifetime.

That’s not a marketing claim. After tracking procurement for a mid-sized logistics integrator for six years, I’ve seen the numbers. We switched to Interroll’s standardized roller drives for our sorter upgrades in 2023, and our total cost of ownership dropped by about 18% per line. The savings came from three places they don’t put on the brochure: installation speed, reduced spare parts inventory, and energy consumption.

I’m not a design engineer, so I can’t speak to the finer points of belt tension calculations. But from a procurement and operational reality perspective? The modular approach fundamentally changes your cost profile.

How Interroll’s modularity affects real-world budgets

Let’s take a typical sorter upgrade project. In 2023, we were replacing a non-modular system across two lines. The old setup required 12 different roller sizes, three distinct drum motor configurations, and proprietary controls. Every time a roller failed—which was about quarterly—we needed to order a specific part, wait for it, pay for expedited shipping (honestly, the markup was painful), and lose production time.

After switching to Interroll’s platform, we standardized on two roller sizes and one drum motor variant for 90% of the system. The result: we cut our spare parts inventory by 40%. (Note to self: we still need to audit the 2024 numbers, but I recall it being around $12,000 in freed-up capital.)

The hidden $8,400 annual savings from energy efficiency

The biggest surprise came from energy cost. I compared the old system’s power draw with the Interroll EC310 drive controls over a six-month period. The older system was using about 23% more energy at partial load—which is where most conveyors spend their time. Interroll’s drives run at optimized efficiency even when the line is running at 60% capacity.

Our facility runs two shifts. Annual electricity savings: roughly $8,400. That’s 17% of what we used to spend on power for those lines. (I really should write a full cost-savings report for management.)

But here’s the thing: modular isn’t for every situation

If your system requires highly customized, low-volume components—say, for a niche manufacturing process—a modular platform might not be the best fit. Interroll’s strength is in standardized, high-volume applications where you can benefit from global support and proven reliability. For a one-off specialized setup, you might be better off with a local specialist who can tailor each part.

The vendor who said, “This project might be outside our sweet spot—here’s who does it better” earned my trust for everything else. That’s the “expertise boundary” principle: a good supplier knows where they excel and where they don’t.

So, should you switch to Interroll?

If you’re managing a fleet of conveyor lines with common configurations and you value reduced downtime, lower spare parts inventory, and energy savings—yes, absolutely. The ROI is real, and the data supports it.

But do your own TCO calculation for your specific setup. Don’t take my word alone. Run the numbers. Bottom line: I’d rather work with a specialist who knows their limits than a generalist who overpromises.
