If you’ve ever been in a facility planning meeting, or even helped design a small industrial setup, you’ve probably heard the myth that auxiliary systems eat up way too much space—like they’re these giant, clunky setups that take over half the room before you even get to the main gear. Let me clear that up right now: as someone who’s been an auxiliary systems supplier for over a decade, I can tell you that’s not the case. The “space problem” isn’t with the systems themselves—it’s with how outdated people assume they work. A lot of the big, bulky auxiliary stuff you might be picturing? That’s old tech, from back when efficiency was an afterthought, not a core requirement. Today’s designs are totally different, and the space they need depends way more on how you plan for them, not the systems themselves. Auxiliary Systems
First, let’s get on the same page about what we’re even talking about when we say auxiliary systems here. For context, I work with everything from compressed air units, cooling and heating loops, power backups for critical processes, and even the smaller stuff like hydraulic pumps or filtration systems that keep the main machinery running. These aren’t the flashy, production-line machines everyone notices—they’re the behind-the-scenes gear that keeps the whole operation from crashing. Ten years ago, a lot of these came as single, standalone units that took up a whole corner of a warehouse or plant floor. You’d have a 10-foot-tall compressed air tank sitting by the loading dock, a separate cooling chiller taking up 200 square feet near the main assembly line, and then backup generators parked in a utility room that was only supposed to be for storage. That setup made sense once, but it’s a terrible use of space for modern facilities.
Now, let’s talk about the real shift: modular design. This is the game-changer most people don’t realize exists. Back when I started, every auxiliary system was custom-built for one specific space, which meant it was big, inflexible, and wasted a ton of room. Now? We build modular auxiliary systems that snap together like Legos—smaller, pre-engineered units that fit into tight nooks, under mezzanines, or even on the wall if you don’t have floor space. Let’s take compressed air, for example. A few years back, if a shop needed 50 CFM of air, you’d get one big 50 CFM unit that took up 150 square feet. Today, that same 50 CFM can be split into two 25 CFM modular units that fit side-by-side on a wall, or even stacked vertically in a 3×3 foot footprint. No more needing a whole separate utility room just for air gear. And here’s the kicker: this doesn’t mean you’re sacrificing performance. The modular tech actually uses less energy too, because you only run the units you need, not a giant single unit that’s always wasting power when it’s not at full load.
But wait—does that mean auxiliary systems never take up a lot of space? No, not exactly. It all comes down to matching the system to your actual needs, not a generic “one-size-fits-all” guess. Let’s break down the factors that do affect space, because it’s not the systems’ fault, it’s how you size or deploy them. First, load demand. If you run a 24/7 manufacturing plant that needs a continuous 500 CFM of compressed air, a single modular unit might not cut it, but even then, we can arrange those units in a tight, clustered setup that uses way less space than old bulk units. A few years ago, a 500 CFM compressed air system would take up over 800 square feet. Today, a modular cluster is under 400 square feet—half the space, same power, same reliability.
Another big factor is the type of auxiliary system. Critical power backup, for example, does need some dedicated space, but even that’s changed. Old diesel generators were huge, noisy, and required a separate, fire-rated utility room with ventilation. Newer generators can run on natural gas or even hydrogen, and they’re way more compact—some are even mounted in shipping containers that fit on a standard truck, so you don’t need a special concrete pad or a huge room to house them. And if you’re in a space where even that’s too much, you can go with battery-based backup systems, which take up a fraction of the space of diesel generators, plus they’re quieter and require way less maintenance. I had a client last year who ran a small medical device facility in a downtown office building—they couldn’t spare the 500 square feet a standard generator would take, so we put in a 10 kWh battery backup system that fit in a 5×5 foot closet. They have never had an outage, and they’ve got more floor space for their actual production line now.
Wait, but what about older facilities? A lot of the companies I work with have been in the same space for 20 or 30 years, and they’re retrofitting old machinery, not building new plants from scratch. That’s when space feels like an even bigger issue. I get it—you can’t just tear out a wall or extend the plant to make room for auxiliary gear. But here’s the thing: our team specializes in fitting auxiliary systems into existing spaces without major renovations. For example, we had a client that ran a small food processing plant—they needed a new cooling system for their packaging line, but the only open space was a narrow hallway that was only 2 feet wide and 10 feet long. Back in the day, a cooling chiller wouldn’t fit at all, but we built a custom modular cooling unit that’s low-profile, wall-mounted, and fits perfectly in that hallway. They didn’t have to touch any existing infrastructure, no construction delays, no lost production time. That’s the key right there—good auxiliary system suppliers don’t just sell gear, they work with whatever space you have, whether it’s a brand new warehouse or a 50-year-old factory with no extra room.
Let’s also talk about a common mistake people make when planning auxiliary systems: over-sizing. So many companies buy the biggest system they think they might need in 10 years, even if they only need 60% of that capacity right now. That’s when space gets wasted, because you’re putting a giant unit in a small space for no reason. I can’t tell you how many times I’ve had clients come to me complaining their auxiliary gear is taking up too much room, and when we look at their usage data, they’re only using 40-50% of the system’s capacity. If we downsize them to a modular system that matches their actual current needs, they free up 30-40% of the space they were using, and they save money on energy too. It’s a win-win.
Another point people don’t consider is integration. Back in the day, auxiliary systems were separate, so you needed space for all the different pipes, wires, and connections between them. Today, we integrate a lot of that into the system itself, so there’s no extra plumbing or wiring taking up space. For example, a modular compressed air system comes with the piping already run between the units, and the electrical connections are all built in, so you don’t need to add extra conduit or pipes in your facility. That cuts down on space and installation time too—we can get a system up and running in half the time it used to take, with way less disruption to your operations.
Don’t get me wrong—there are edge cases where auxiliary systems do take up a good amount of space. If you’re running a large data center, for example, you need big cooling systems to handle all the server heat, and those do take up a fair amount of floor space. But even there, modern cooling systems are way more compact than they used to be, and we can arrange them in raised floor spaces or on rooftops, so you’re not using valuable server room space. Rooftop mounting is another underutilized trick—most facilities have unused roof space that’s perfect for auxiliary systems like compressors, generators, or cooling units. We helped a client with a 100,000 sq ft distribution center put all their auxiliary gear on the roof, which freed up over 1,000 sq ft of floor space for storage. They didn’t have to change anything inside their facility, and the rooftop setup actually improved the system’s efficiency because the cool roof air helps keep the units from overheating.
I know a lot of facility managers are paranoid about adding more gear because they’ve had bad experiences in the past—you add a new system, and suddenly you’re tripping over pipes, losing floor space, and dealing with maintenance headaches. That’s why we make sure every system we sell is designed with accessibility in mind. Modular units aren’t cramped together so tight you can’t get to them—we leave enough space for maintenance, and we design the units so parts are easy to replace without taking up extra room. So you’re not sacrificing usability to save space.
Let’s circle back to the original question: Do auxiliary systems require a lot of space? The short answer is no—they used to, but that’s outdated tech. The real question you should be asking is how you plan for them, and who you work with to pick the right system for your space. If you’re designing a new facility, modular, integrated auxiliary systems will fit into your space without wasting a single square foot. If you’re retrofitting an old facility, there are ways to fit auxiliary gear into tight spaces without major renovations. The only time you’ll end up with a bulky, space-hogging auxiliary setup is if you go with outdated, over-sized systems from a supplier who doesn’t tailor to your specific needs.
At the end of the day, auxiliary systems are there to support your main operations, not take over them. If your supplier is selling you a system that eats up half your floor space for no reason, they’re not doing their job right. We’re always happy to look at your space, your usage, your current pain points, and put together a solution that fits exactly what you need—no extra space, no wasted energy, no headaches.
