For over three decades, CTT Systems has been on a mission that most passengers don’t even know they need. Its solution reduces fatigue, supports immune function, and preserves taste during air travel by tackling an invisible culprit: dry air. As the leading producer and designer of humidification and anti-condensation systems for aircraft, the Swedish company has revolutionised cabin comfort for everyone from business jet owners to commercial airline passengers.

CTT has built its reputation on expertise in a highly specialised field. Now, after a decade of exhibiting at Aircraft Interiors Expo (AIX) alongside Collins Aerospace, CTT is stepping into the spotlight with its own stand, within the show’s new Business Jet Zone.

We spoke with Eric Beverage, Senior Director of Sales Americas, about CTT’s journey with AIX, how they’re educating the industry about the company’s innovation, and why it’s so desperately needed in the cabin – one of the driest places on earth!

What distinguishes CTT from other companies in the aircraft interiors sector?

Eric Beverage:
CTT has a single focus: humidification and anti-condensation systems for aircraft. That’s all we do, and we’ve become the experts in that space. We’re a publicly traded Swedish company with about 80–100 employees, offering certified systems for both retrofit and OEM installations. Our uniqueness comes from our specialisation – one product area, executed exceptionally well.

Why would a company be looking for your solutions? What’s the need you’re addressing?

Eric:
Cabin air at cruising altitude is incredibly dry – often dropping to just 3–5% humidity after a few hours, compared to 40–50% in a typical home. That environment contributes to fatigue, dehydration, and the overall “worn out” feeling after long flights. Our system integrates with the aircraft’s environmental control system to maintain a much more comfortable 22–23% humidity throughout the cabin, which has a significant impact on how passengers feel during and after their journey.

We initially focused on business jets and VVIP aircraft, where passenger wellness is a major priority, but the advantages are universal. Better humidity means a noticeably better cabin experience for anyone onboard.

Your market spans both business aviation and commercial airlines. How does that split work?

Eric:
We capture probably about 95% of the business aviation market. High net worth individuals have greater ability to change their environment, and they do.

On air transport, we’re still educating a lot of airlines on the benefits, but we have a strong portfolio already. We’re an optional standard from the OEM for the Airbus A350, the Boeing 787, and the Boeing 777. Airlines that have chosen us have often taken our system in an aftermarket or retrofit solution to create an even better environment for their passengers.

When did CTT start attending AIX, and what were some standout moments?

Eric:
CTT has been attending AIX for roughly 10 years now. Up until this year, we exhibited with Collins Aerospace. That’s where I come from as well; I was a Collins employee for about 18 years before joining CTT.

Our standout moment at AIX would probably be Air India. That was our first big collaboration project – the customer relationship began at AIX, and now we have our systems on a lot of their aircraft.

What initially drew CTT to AIX in the first place?

Eric:
There are a lot of benefits to AIX. First, obviously, networking with current and future clients. Second is technology; you have to keep up with what others are doing, whether that’s your competitors or your partners.

AIX is a complete showcase for air transport, and to be able to meet as many clients as you can in those three days? That’s huge for any supplier. It’s really about networking, innovation, and being cabin-focused. I like to say “cabin-focused” rather than “interiors,” because there are a lot of companies like CTT – we’re a non-tangible cabin product supplier. You don’t really see our product, but you feel our product.

How have you seen the industry change over recent years, and how is CTT adapting?

Eric:
From a passenger standpoint, business aviation clientele and owner-operators are looking more for comfort, technology, and convenience. They want a smooth transition from their house to their yacht to their airplane. They don’t like interruptions – whether that’s connectivity, comfort interface in the cabin, or just scheduling.

I’ve noticed over the last couple of years that clients are less focused on the style of the cabin, and more focused on the quality and comfort of the cabin. That’s where we come in.

Sustainability is one of CTT’s values. How do your solutions help the environment?

Eric:
Our sustainability story is really driven by our anti-condensation system. At altitude, ice forms inside the aircraft shell and later melts into water, soaking insulation and adding unnecessary weight – which means higher fuel burn. Our system removes that moisture before it can accumulate, typically saving 100–200 kilos per aircraft. It also protects sensitive components like antennas and electronics, reducing maintenance needs and extending their lifespan.

What should people expect from your stand at AIX 2026?

Eric:
We’ll be showcasing our expanded OEM partnerships, particularly our new collaboration with BBJ: all BBJ 737s will come with our humidification and anti-condensation system. Visitors can also see demonstrations of how our systems integrate with next-gen aircraft environmental controls.

Our primary focus at shows is typically around continuing to educate people on the benefits of humidification and their environment in the aircraft – whether that’s a business jet or commercial aircraft.

AIX celebrates its 25th edition next year. Looking ahead another 25 years, what opportunities do you see?

Eric:
For ourselves, obviously, I would hope for a healthier environment in terms of air quality and climate within the cabin. If you’re going to be in an enclosed capsule for as long as you are – especially from a business jet perspective where clients spend a lot of time in their aircraft – our goal is to make it the best quality environment possible from an air standpoint.

In general, it’s about technology, innovation, and the conveniences of everyday life. The general public’s expectation is that if you’re going to pay as much as you do to fly, you should have the conveniences you would if you were sitting at your house. Your connectivity, your service, the quality of food – everything you would expect from a five-star hotel or a very nice yacht, they expect on their aircraft.

I really think it’s innovation that will drive the next 25 years.

You’ve been exhibiting at AIX for 10 years now. What advice would you give to someone exhibiting for the first time?

Eric:
AIX is a very large and diverse trade show, so just be prepared to meet and speak to all types of aircraft owners and operators. Whether that’s airline, business jet owner-operators, charter operators, freight operators, or even government-related owner-operators.

And don’t forget about vertical lift or rotorcraft aircraft. Even in the last 10 years, you get a very big, diverse group of people that come to AIX.

Just be prepared. It’s not just an airline show anymore!

In three words, how would you sum up AIX?

Eric:
Innovative networking, cabin-focused. There are a lot of words you can sum it up with, but those three capture it.
