“In Europe, over 250 ice rink operators have started to use a

vortex process technology, to lay and resurface ice rinks.

This technology removes micro-bubbles from water by

spinning the water into an ordered vortex movement.

Through this process, micro- bubbles are driven to the

inside of the swirl and then released. As a result of the

process, with less micro-bubbles and impurities in the water

- than through the traditional process of heating the water

to make the ice – the ice is harder, faster, more transparent

and produces less snow.
