Bellsolà - food industry: CAREL transcritical CO2 in warm climate

Bellsolà - food industry: CAREL transcritical CO2 in warm climate
Thanks to the partnership between Fredvic, SCM and Carel Industries, the Spanish Bellsola chain, as a part of one of the largest industrial groups in Catalonia, installed in its main production plant in Girona two completely green food refrigeration and cooling tunnels.
The freezing tunnel is a system that cools in an extremely short amount of time products requiring extremely low temperatures before proceeding in their productive process, as in case of pre-baked bread from frozen dough.
The concerned compressor racks were provided by SCM, a leader in delivering comprehensive packaged solutions that focuses on a vertical development, high components accessibility and compactness in space.
It‘s a two machines booster with an evaporating temperature of -42 °C and a low temperature refrigerating power of 275 kW. The total installed power is about 550kW.
The machines are installed in Girona, dealing with demanding environmental conditions for CO2 transcritical applications. The 38 °C maximum ambient temperature lead the working pressures to tap 100barg in the high-pressure circuit. An adiabatic cooling system (Chillbooster) was installed to optimize the machine operation even under these critical operating conditions.
The two units, made on PNC carpentry, feature an integrated gas cooler. Each unit is composed by 5 Bitzer 4NSL-30K low temperature compressors (-42 °C / -3.5 °F) and 5 4CTC 5-30K Bitzer compressors for midrange temperatures (-3.5° C / 38 °C / 95 bar)
The plant construction was entrusted to FredVic, a company in the field of refrigeration for more than 30 years demonstrating quality, professional skill, experience and a fully customized service based on innovation and power efficiency.
