Epta, a leading system manufacturer of CO2 commercial refrigeration systems, was commissioned by supermarket chain Simply to install the first full CO2 system in one of its stores located in Bilbao, Spain. The CO2 transcritical booster solution for normal and low temperature cabinets and cold rooms aims to reduce the store’s energy costs and carbon footprint, while maintaining optimum performance in a warm climate. + PHO

Epta operates worldwide in developing tailor-made refrigeration solutions for retailers seeking future-proof alternatives. In Spain, HFCs are subject to taxation, thus Epta provided a turn-key CO2 alternative in collaboration with Norelefri, the company responsible for installing the system.

EPTA’s ECO2-Small for high efficiency and reduced CO2 emissions

The Epta ECO2-Small refrigeration system, designed for small and medium sized supermarkets, enables retailers to increase their store’s efficiency as well as reduce energy costs and carbon emissions. In addition, investments costs are also reduced thanks to tax exemptions granted in Spain when not using HFC gases.

The power pack ECO2-Small, produced in the Italian factory of Costan- Limana, features the following:

  • Compact booster transcritical compressor rack (2380 x 780 x 1800mm)
  • 2 semi-hermetic compressors, low temperature for a total of 24 kW
  • 3 semi-hermetic compressors for 114 kW, positive temperature

Both positive and negative compressors work with a frequency control that allows power modulation and adjustment depending on the real demand of the store. Gas condensation is realised by an external gas cooler equipped with Carel Chillbooster adiabatic air cooling system.

The air conditioning and refrigeration have been integrated, optimising the consumed energy and therefore increasing the total efficiency of the store. Electronic controllers Carel pRack pR300T constantly refine operations of all functions including the distribution cassettes, refrigerated cabinets and coldrooms.
