CROSSFIT AARHUS
Big CrossFit Box had ventilation challenges
Menu
CrossFit Aros is a classic crossfit box with room for all types of members – and where members become a part of a large community. CrossFit Aros opened its doors in December 2018 in Aarhus, and since then the number of members has been increasing quickly and currently counts 250 persons.
Shortly after its opening, they stumbled into quite a challenge. The authorities’ requirements to the ventilation were stricter than first anticipated.
“As a relatively young company, we did not like the idea of tying our money in a big chrome ventilation system that costs a fortune. So we ended up with the solution of big fans,” owner of CrossFit AROS, Claus Aagren explains, who already knew about the effects of big fans from his days in the U.S. “More specifically we reached the solution of installing three big four meter HVLS-fans from Nordicco in the ceiling, which could cover the whole arena. And the authorities gave us the green light.”
According to CrossFit Aros, they now get the feeling that air is well circulated around the large room. During the installation, it was decided to place the three large HVLS fans in the middle of the facility. However, the area is divided into 4 specific workout zones. Because of this setup, an internal discussion sparks once in a while about the specific placement of the big fans. Some employees are curious as to whether the fans would be able to give even more air to the hardcore training zones if you placed them directly above a training zone.
In Claus Aagren’s mind the ‘non-permanent’ aspect is definitely a plus: “Only time will tell whether or not we choose to test out a new position of the fans in the future. Another good thing about this solution is that it isn’t 100% permanent. The ceiling fans can be removed relatively easily and moved to a new location in the arena if that is what we wish to do.”
”We are located in a huge facility – a former warehouse – of 1.200 square meters and with 6 meters to the ceiling. So the air has a tendency to stand still in here. We knew we were challenged with regards to ventilation, but the authorities’ requirements were harsher than we had predicted. So all of a sudden, we faced two options. Either installing a classic ventilation system, which costs anywhere between 500.000 to 1 million kroner (DKK) – or find an alternative quickly!”
The solution meant that CrossFit Aros could avoid spending hundreds of thousands DKK on a large traditional ventilation system. Instead, they solved their ventilation challenge for less than 100.000 kroner. The solution has remedied most of the problems with the air in the large facility. And Claus Aagren is particularly happy that he solved the problem in a way that left room to invest in the things that give direct value to their members.
When asked what CrossFit Aros’ employees have to say about controlling their 3 big fans, Claus Aagren responds promptly: “In relation to the control box, it is incredibly simple. It works impeccably in day-to-day operations. It’s so easy to handle. So we also play around with the fans sometimes, for instance to feel the difference between forward and reverse mode – and of course with the speed of them.”
