Carrier - As the only system manufacturer Carrier displayed its CO2 rack system available for local market. ‘Mini CO2OL compact’ with capacities 18-185kW for MT and 3-70kW for LT. According to Carrier representatives this year there will be more pilot projects with CO2 as a result of ongoing discussion going in right direction. The interest comes not only from international companies but also local brands. Recent accidents related to ammonia leak in China, help shifted the attention to CO2 systems also for cool room applications. According to Carrier a step by step approach is necessary with proper infrastructure, trained technicians and enough hands on experience. To address this need in the market, Carrier is operating a CO2 showroom in Shanghai.
Carel - The supplier of valves and controls for CO2 and ammonia solutions showcased components for CO2 transcritical Booster (pRack pR300T) and CO2 Cascade Subcritical (pRack pR300) systems. Carel also show exhibited its control solutions for both small and large footprint stores.
Danfoss - Danfoss exhibited a series of state-of-the-art refrigeration technologies with natural refrigerants and their applications in China. This year, the company displayed its star product the ICF Flexline valve station. The valve is designed for both low and high pressure refrigerants and for industrial refrigeration applications. It is especially suitable for CO2 and for industrial refrigeration secondary cooling systems with ammonia and CO2. Also on display was ADAP-KOOL System Manager AK-SM 800, control system for supermarkets accessible from a web-browser or mobile device, securing food safety, robust operation and energy savings for stores using conventional or natural refrigerants.
Dorin - This year the compressor manufacturer showcased its CDS Range and CD400 Range of CO2 compressors for subcritical and transcritical applications. The CD400 Range offers displacement from 9.48 to 30.5 m3/h.
GEA Refrigeration - GEA exhibited pair of CO2 compressors: The GEA HGX12e subcritical CO2 applications for industrial and commercial refrigeration; and the GEA HGX46 CO2 T compressor, a semi-hermetic six-cylinder reciprocating compressor with drive motor for part winding start that can be used both in transcritical and subcritical systems.
