It includes a subcooling unit in the refrigeration circuit and no additional systems like water spray, external subcooling or adiabatic gas coolers are needed. …
MembreCIMCO Refrigeration
CIMCO Refrigeration, as Canada's largest industrial refrigeration contractor and a leader in natural refrigerant-based technology, has significantly increased its commitment to climate-friendly ice rink refrigerants. Recognizing the importance of reducing greenhouse gas emissions, CIMCO no longer produces recreational ice rink packages that utilize high-GWP refrigerants, including HFO blends like R513a. The company's President, David Malinauskas, emphasizes CIMCO's recognition of the industry's role in eliminating super-polluting refrigerants such as hydrofluorocarbons (HFCs). The new offerings align with the Kigali Amendment and Montreal Protocol, exceeding the stringent regulations set by the California Air Research Board (CARB) that require new ice rinks to use refrigerants with a GWP of less than 150. CIMCO has embraced climate-friendly refrigerants like CO2 and ammonia, which have zero or negligible GWP, establishing them as the new industry standards. CIMCO's commitment to environmentally conscious practices is exemplified by its construction of numerous sustainable ice rinks across North America. Notable projects include the Evergreen Brick Works rink in Toronto, a renowned leader in urban sustainability, and the Oak Park Ice Rink in Stockton, CA, which will become the state's first CO2 ice rink. With a redesigned product lineup, CIMCO now offers four climate-friendly ice rink refrigeration packages, along with heat-recovery technology to assist ice rinks in further reducing their carbon footprint. Malinauskas expresses enthusiasm for collaborating with ice rink owners and operators throughout Canada and the United States. Whether it involves constructing new net-zero facilities or transitioning existing facilities towards a climate-friendly future, CIMCO is dedicated to working together to achieve sustainable solutions. With its unwavering commitment to environmentally friendly refrigeration practices, CIMCO Refrigeration continues to lead the industry in promoting climate-conscious ice rink refrigerants and contributing to a greener future. …
