Born to Freeze

          Refrigerated warehouses are becoming more and more popular, providing the needed back-up support for fresh and frozen food home delivery.                           However, actual F-gas regulation is imposing severe hurdles in deploying HFCs for these applications, while end users are constantly looking for an alternat ive to ammonia based refrigeration system. CO2 trans-critic al units were never coming into the picture mainly due to the lack of large components, such as compressors: this made it impossible to cost-effectively apply CO2 trans-critical technology to such large duties systems. However, with the usual strong focus on market requests, DO RIN has once again shaped the future and recently developed and launched the largest CO2 trans-critical compressors range, with displacements u...

CO2 refrigeration equipment COP has been one of the main limiter for the use of this natural refrigerant in warmer climate zones , with HFCs technology claiming to provide better seasonal energy efficiency figures for typical Southern European climate profiles. The use of DORIN compressors in conjunction with ejector technology and parallel compression has completely over-turned the previous situation: thanks to utmost compressors performances and to the introduction of new system concepts, CO2 is now able to over perform other technologies in all climate zones, including Southern Europe . These developments led leading GDO stake holders to turn in favour of CO2 refrigeration equipment also for their assets located in Southern Europe, e.g. Italy, one of those being Carrefour.  Thanks to their focus on environment friendly solutions, DORIN has partnered with ENEX and REFSYSTEM in the realization of several Italian supermarket point of sales owned by CARREFOUR , featuring DOR...
