Country of installation france-flag

Overview 

A leading French retailer has taken a significant step toward sustainability by refitting its supermarket in Lambesc, a picturesque town in Southern France. The goal: to embrace the future of refrigeration and heating with a single, innovative solution. 

The Challenge

Supermarkets face increasing pressure to reduce their environmental footprint while maintaining high performance in cooling, heating, and hot water supply. The retailer sought a system that could deliver on all fronts—efficiency, sustainability, and operational reliability—using natural refrigerants. 

The Solution

The store’s transformation centered around the installation of a unique Senna CO₂ rack, configured in a 3+2+3 setup. This advanced system powers: 

  • Medium Temperature (MT) Refrigeration: 150 kW capacity 
  • Low Temperature (LT) Refrigeration: 30 kW capacity 
  • Domestic Hot Water (DHW) & Space Heating (SH): Enabled by dual heat recovery 

To further boost energy efficiency, the installation incorporates combined liquid and vapor ejectors. This technology maximizes performance while minimizing energy consumption. 

Results & Impact

The outcome is a single, integrated Climate-Tech system that meets every operational need—cooling, heating, and hot water—using only natural refrigerants. The solution delivers: 

  • High Performance: Reliable operation across all temperature zones 
  • Energy Efficiency: Enhanced by advanced ejector technology 
  • Sustainability: Reduced carbon footprint through the use of CO₂ and heat recovery
