Vortex Water Treatment

By September 27, 2017December 26th, 2021Briefs

What is it?

Vortex water treatment is specifically designed to reduce energy use during the resurfacing of ice rink slabs. An ice slab is the core feature of an ice rink, and the quality of the ice surface is critical. The ice surface needs to be free of imperfections for good skating. Resurfacing the ice slab is an ongoing operation and is traditionally done by spraying hot water onto the rough ice surface. Hot water is traditionally used because it produces a higher quality surface by allowing air bubbles to escape during the extended freezing time.

How does it work?

Vortex water treatment uses a specialized nozzle that generates a vortex, which removes the bubbles from water as it is sprayed onto the ice surface. This means cold water can be used, which saves water-heating energy and ice-making energy.

What are the most appropriate applications?

Ice rinks. There may be other applications, but the technology is specifically designed for ice rinks.

What are the savings?

The savings are great – verified savings of 79% for natural gas and 28% for electricity[1].

What are the non-energy benefits?

Having a high quality ice surface is the cornerstone of ice rink businesses, so the impact of efficiently resurfacing ice slabs goes far beyond energy savings.

What is the cost?

The cost of the technology is approximately $28,300.

What is the status/availability of the technology?

This technology is readily available.

What kinds of incentives/programs are available?

Right now, this technology would typically be evaluated under Custom Rebate programs. Incentives will vary depending on customer specifics.
