The many personal skating records at the qualifying tournament (WKKT) in Thialf (26-28 December) were not partly achieved by turning a number of air vents. This is argued by Marc Winters, director of the Frisian skating stamp, in response to ‘recent questions from the skating world and in the media’.
There has been an alleged ‘tailwind’ since the rosters in Thialf turned a quarter turn in mid-November. “The performance of the skater is always a combination of many factors and at the core these are the shape of the day, the air pressure and the quality of the ice floor,” Winters says. “Besides the fact that Thialf received positive feedback from many participants about the ice quality during the CHP, the exceptionally low air pressure was a major factor, especially on the second and third competition day. In our view, turning the grids has had no influence on this. ”
According to Winters, the air handling system in Thialf is not designed to create tailwind on the runway. It is intended to create an optimal climate for the skaters and to create an air curtain between the boarding and the grandstand to neutralize any influence of the public on the track.
The adjustments to the air vents have been made to ‘close holes in the air curtain’, according to the director. These were created because no grids were installed in several places around the track over a number of meters during the renovation and partial new construction.
“By blowing diagonally instead of straight up, these gaps are closed”, Winters explains. “Rotating the grids is aimed at preserving the existing air circulation above the track and not at creating extra circulation. The settings of the air treatment have also not been changed in the sense that blowing would be harder or softer. That is definitely not the case. ”
