Carnot CO2 Transcritical, NH3/CO2 Cascade & Full CO2 Refrigeration Systems – Specializing in R744 Refrigerant

Carnot Refrigeration

Carnot Refrigeration is a Canadian company headquartered in Quebec and established in 2008 with the goal of addressing the HVAC&R industry's failure to provide industrial and commercial clients with a thermodynamic option that would diminish environmental impact. Carnot Refrigeration makes a conscious effort to design refrigeration systems and heat pumps that cut down on the use of polluting refrigerants. It has taken the lead in its field by creating high-efficiency refrigeration systems designed by specialized engineers and manufactured in an environmentally controlled plant or at a constraint-free site. Carnot Refrigeration is experienced in meeting the needs of sports facilities (arenas), supermarkets, distribution centers and the agri-food industry.
