"Our instruments need it," says Florian Rittweger, Sales Manager at Thomann, succinctly summing it up. Wooden instruments like guitars and violins are particularly sensitive to excessively dry air. Without regulated humidity, they risk cracking, warping, or loss of sound. Wind instruments also benefit indirectly, as their wooden components, such as reeds, are also sensitive to moisture. The optimal relative humidity is between 40–50% for stringed instruments and 35–40% for wind instruments. Besides protecting the instruments, presentation in the sales area also plays a crucial role. "Sufficient humidity binds dust, and the resulting clean surfaces enhance the appeal of the display," explains Florian Rittweger. "Humidification helps ensure that the sales area remains visually attractive. Customers experience a pleasant, fresh atmosphere that invites them to linger—a factor not to be underestimated in brick-and-mortar retail." But controlled humidity isn't just important for the sales floors: "Above all, we want to create attractive, comfortable workplaces and protect the health of our employees," explains Alexander Schell, Head of Construction Projects, regarding the continuous expansion of humidification systems in Thomann's administration, call center, and customer service areas over the past few years.

For humidification, Thomann uses a Condair Direct room humidification system. This solution employs small, high-pressure nozzles that transform water into a micro-fine mist at up to 70 bar. This barely visible mist is immediately and completely absorbed by the room air, ensuring a consistent increase in humidity. The system is controlled by hygrometers that continuously measure the humidity in the room. As soon as the set target value is undershot, humidification activates automatically until the optimal humidity level is reached again. This can be done room by room or individually for specific zones, allowing for customized humidity levels in different retail spaces, offices, or meeting rooms, for example. For Florian Rittweger, this is a crucial advantage in sales: “Different instruments require different humidity levels. Direct room humidification allows us to control this very flexibly.” Before nebulization, the water is completely demineralized and disinfected. This takes place in a pre-treatment system that is part of the Condair humidification system. The integrated, multi-stage water treatment system is housed in portable containers, which are exchanged every six months by the manufacturer for fully serviced and cleaned systems. “As users, this means we don’t have to worry about maintenance ourselves and can be confident that hygiene and operational reliability are always guaranteed. That’s particularly important to us,” emphasizes Alexander Schell. In addition, the humidification system is certified by the German Social Accident Insurance (DGUV) and is regularly tested and recertified on-site by the Association of German Engineers (VDI) according to VDI 6022, Part 6. These integrated, multi-stage water treatment systems are housed in portable containers that are exchanged every six months for fully serviced and cleaned systems as part of the manufacturer’s standard service.
