The Crown Coliseum in Cumberland County, NC, is home to the Fayetteville Marksmen minor league hockey team. It also became the home to a brand new Zero Zone ColdLoop™ Ice Arena Chiller.

After years with an old R-22 system, Cumberland County turned to Zero Zone for a new chiller using ammonia. Ammonia is an industrial-grade refrigerant. “Ammonia as a refrigerant is an excellent choice,” Industrial Sales Manager John Collins explained. “It is perfectly suited for a low-temperature chiller application: highly efficient and very reliable.” Ammonia is a future-proof refrigerant with no ozone depletion potential (ODP = 0), no global warming potential (GWP = 0), and high performance. It is one of the most prominent natural refrigerants, which is appealing as an environmentally responsible option.

Cumberland County also chose many excellent cost-saving features: highly efficient screw compressors, evaporative condenser, PLC control system, variable frequency drives (VFDs), and, most notably, a heat reclaim system. Their heat reclaim system repurposes compressor discharge heat to warm the subfloor under the ice, ensuring that the subfloor will not freeze or crack. Heat reclaim systems repurpose the waste heat that otherwise would be released at the condenser without benefitting the arena.

Most importantly, the chiller produces high-quality ice for the hockey team. The Fayetteville Marksmen skate confidently because their home ice is formed by a ColdLoop™ Chiller.
