Large CrossFit Box solved ventilation challenges by installing large ceiling fans

Large HVLS fan

CrossFit AROS is a CrossFit box with room for a broad mix of members – and a place where members become part of a larger community. The box opened in Aarhus in December 2018. Since then, membership has grown rapidly.

Worth knowing about the solution

  • 3 Northern Air® HVLS ceiling fans installed
  • Chosen as an alternative to a traditional ventilation system
  • 4,5 metres in diameter
  • Installed in 2019
  • Used in a large CrossFit hall of 1,200 mwith a ceiling-height of 6 metres
  • Quiet operation without uncomfortable drafts
  • Give the sensation of a 5°C temperature decrease on warm days

An unexpected ventilation challenge

Shortly after opening at the end of 2018, CrossFit AROS ran into a major ventilation challenge when the authorities imposed stricter requirements than anticipated.

“As a relatively young company, we weren’t exactly thrilled about tying up a lot of money in a big, elaborate ventilation system that cost a fortune. So we chose an alternative solution with large ceiling fans,” says CrossFit AROS owner Claus Aagren, who was already familiar with the concept of ceiling fans from his time living in the US.

“More specifically, we ended up installing three 4.5-metre ceiling fans from Nordicco, which could cover the entire hall. And the authorities gave us the green light.”

A much cheaper alternative

“They are incredibly simple to control. Everything works smoothly in day-to-day use, and they’re easy to operate. So we – the staff and I – also play around with them from time to time, for example to feel the difference between forward and reverse mode, or to see what difference the speed makes.”

“We’re based in a huge 1,200 m² warehouse with six metres to the ceiling, so the air has a tendency to stand still in here. We knew ventilation would be a challenge, but the authorities’ requirements were more extensive than we had expected. Suddenly, we were faced with either installing a conventional ventilation system costing between DKK 500,000 and DKK 1 million, or finding an alternative.”

From DKK 1 million to under DKK 100,000

The solution meant that CrossFit AROS could avoid spending up to DKK 1 million on a large traditional ventilation system and instead address its ventilation challenge for under DKK 100,000.

The solution has addressed the biggest air circulation issues in the large hall, and Claus Aagren is particularly pleased that it has left room in the budget to continue investing in the things that create direct value for their members.

Members’ feedback matters

CrossFit AROS places great value on community, Claus Aagren explains:

“Community matters to us. You don’t just come here to train for an hour. You’re also here to make good friends, exchange ideas and learn from each other.”

That is why the members’ response to the large, highly visible ceiling fans was also an important part of determining whether the solution was a success. Ultimately, it is about user satisfaction:

“Our members are really happy with them – and with the way they work. It’s obviously a very visible solution, but we’ve had a really positive response from our members. That’s great!”
