Let’s leave the world of technology behind us for a moment and take a relaxing break at a spa. Here at the edge of the swimming pool, it is warm and cosy. The water invites you to take a dip and fall off the planet. Simply lay back and enjoy the soft sound of the waves lapping against the edge of the pool. Take a deep breath and relax …
Ok, that’s as far as this text can go without talking about fans, so back to business. That’s because the GreenTech EC technology from ebm-papst plays a decisive role in many swimming pools around the world in creating a comfortable and tranquil relaxation experience. It ensures the right temperature and extracts unwanted humidity. Ridvan Cehic is Managing Director of Mollerus GmbH, a company with just 13 staff based in Meersburg on the banks of Lake Constance, and knows how important the benefits of EC technology are for his sector.
“We specialise in systems for hotels and private users”, he says. “Here, we supply fully automatic ventilation blocks that are completely tailored to the needs of swimming pools.” His devices take all the necessary measurements in the room that are required to regulate the air supply and extraction via the continuous, speed-variable fans. The ventilation blocks control the temperature using heat recovery, with the system removing humidity using outside air or a heat pump, depending on the installation situation.
“We listened very closely when selecting the fans.”

An oasis of tranquillity in the spa Mollerus’ devices are all produced for continuous operation. They have to run for at least five hours per day to create the right climate conditions. The running time also depends upon how long the pool or spa is open, for example, as well as whether the pool is covered or not. To allow guests in search of relaxation to enjoy the pool in comfort, disruptive noises must be prevented at all times.
“We listened very closely when selecting the fans”, says Cehic. “We came to the conclusion that using multiple smaller fans in our units would generate less noise than a large fan of the same output.”Aside from a few exceptional cases, no additional noise reduction measures were required – a clear cost advantage. The second advantage of this decision was that Mollerus could offer its ventilation blocks as modular systems, with up to eight energy-saving GreenTech EC fans. “This means we can provide our customers with precisely the right unit for any size of room”, says Cehic. The EC blowers designed for Mollerus run quietly, ensuring a relaxing atmosphere and allowing spa guests to enjoy their visit.
