Seeking to provide area residents and visitors with a new type of holiday activity, the City of Farmers Branch and the Dallas Stars made plans to create a seasonal, recreational ice skating rink. The venue would be constructed on a 100 percent outdoor site, unshaded from rain, sun and temperatures that ranged from the low 30s to the high 70s. To create and maintain a quality ice surface that would be available for use throughout the season, the Dallas Stars facility team sought a system that would be reliable and redundant. With the chiller plant to be located close to the rink, quiet operation was also important to maintain a pleasant environment for skaters. In order to be ready for its November opening, the construction project needed to be completed in just three months.
The Dallas Stars began researching solutions for the new ice rink. Aware of the tight timeframe, Trane immediately met with the organization’s facilities team to gather a complete understanding of the group’s objectives and designed an intricate package to meet their requirements. The Trane proposal offered a complete solution that utilized the technical knowledge of its engineering team, unique equipment solutions, project management guidance, and the expertise of its local service team. After reviewing competitive proposals, the Dallas Stars selected Trane as their project partner.
“Constructing an outdoor ice rink was brand new to us, so we did our research,” said Don Fernandes, facilities manager, StarCenter-Farmers Branch, Dallas Stars Hockey.
“We liked the comprehensive proposal offered by Trane,” said Mark Servaes, general manager, StarCenter-Farmers Branch, Dallas Stars Hockey. “Plus, they came highly recommended.”
Creating a unique solution for fast installation
The Dallas Stars facilities team began by grading the land so the ice surface would be level. Trane moved forward to design an all-inclusive mobile chiller plant that would be elevated to keep it out of the mud of the new construction site. Trane engineers considered equipment options, evaluating each selection to ensure it was sized correctly to provide the performance needed to maintain quality ice without shielding. The service team fabricated the system on a pad, mounted to a trailer that could be moved into its ﬁnal placement. Factory-installed features, including a pre-wired, factory-tested pump package, buffer tank, ﬂow switch and water strainer helped to speed installation.
Providing efficient, reliable, quiet operation
Two temporary 120-ton Trane® CGAM air-cooled scroll chillers were selected for the needs of the seasonal ice rink. The CGAM scroll chillers offer a combination of high efficiency, low sound operation and compact size. The simple design of the chillers provides maximum reliability, with all major components easily accessible should service be required. The quiet operation of the Trane CGAM chillers helps ensure little disruption for skaters and visitors of the nearby StarCenter.
Offering high-quality, leak-free, ﬂexible ﬂooring
The system included ﬁfteen 63 ft IceMat® ﬂooring panels from CALMAC®, a portfolio of Trane, for the 6,363 sq ft ice rink; a 600 gallon buffer tank, which utilizes a 45 percent glycol solution; and a 30 HP vertical inline pump. Ideal for temporary or permanent rinks, the set up circulates glycol through the ﬂooring tubes, and as the mats cool, sprays water mist on the rink, which freezes within hours to cover the mats. Engineered to meet stringent standards, the mats create a smooth surface for ice skaters. In addition, the IceMats are made of high-quality materials making them corrosion-resistant, leak-free and pressure-capable, and are backed by a three-year limited warranty. CALMAC IceMat rink ﬂoors also provide a greater heat-exchange surface area than conventional indirect or direct refrigeration piping systems, enabling the mats to make high quality ice even when air temperatures are high.
The prefabricated, easy-to-install IceMat ﬂoors unroll much like a carpet, helping to lower construction costs. With each mat modular in design, the CALMAC® IceMat® rink ﬂoors offer the Dallas Stars the ﬂexibility to increase or decrease the size of the outdoor rink at any time.
The Dallas Stars and Trane constructed the ﬁrst-ever outdoor arena in Farmers Branch, Texas, providing high-quality ice even when temperatures reached the mid-70s. With Trane engineers accurately predicting performance needed, the temporary Trane chillers provided the redundancy desired for reliable operation of the arena, with low noise levels to maintain the pleasant entertainment environment. The all-inclusive mobile chiller plant and easy-to-install CALMAC IceMat ﬂoors enabled the Dallas Stars to open the seasonal ice rink in time for the holidays.
“Once the system was up and running, it was ﬂawless. Plus, I don’t think the chillers used more than 140-tons at any one time,” said Fernandes. “The chillers were really quiet. They were located close to the rink and they were no noisier than a home air-conditioning unit.”
“We plan to construct the rink again next year. It was well used by the community and visitors. Plus, we increased revenues by about $50,000,” said Servaes. “We had a good relationship with our account team and a true business partnership with Trane. We never felt we were working alone on the project.”
