Project Overview 

In partnership with one of Spain’s largest installers, Enex Technologies delivered a state-of-the-art Cascade CO₂/NH₃ refrigeration unit, specifically tailored for the agrifood sector. The system was designed to meet the demanding requirements of freezing chambers operating at -22°C, ensuring both high performance and sustainability. 

The Challenge 

The agrifood industry requires robust refrigeration solutions capable of maintaining ultra-low temperatures, often in challenging outdoor conditions. The client needed a system that could deliver reliable cooling, maximize energy efficiency, and align with modern sustainability standards. 

The Solution 

Enex Industrial provided a custom Cascade system that combines the strengths of natural refrigerants—CO₂ and ammonia (NH₃)—with advanced engineering for optimal results. Key features include: 

CO₂ Module: 

  • Cooling capacity: 429 kW 
  • Evaporation temperature: -31°C 
  • Condensation temperature: -5°C 
  • Heat recovery: 50 kW (Water +40°/+50°C) 
  • Compressors: 3 x BITZER 

NH₃ Module: 

  • Cooling capacity: 550 kW 
  • Evaporation temperature: -10°C 
  • Condensation temperature: +35°C 
  • Compressors: 2 x BITZER OSKA 

This all-in-one solution is engineered to deliver high performance even in extreme outdoor temperatures, making it ideal for the agrifood sector’s most demanding applications. 

Results & Impact 

The Cascade CO₂/NH₃ unit has set a new benchmark for industrial refrigeration in Spain’s agrifood sector by: 

  • Ensuring Reliable, Ultra-Low Temperature Performance: Consistent operation at -22°C for freezing chambers 
  • Maximizing Energy Efficiency: Through integrated heat recovery and advanced compressor technology 
  • Promoting Sustainability: Use of natural refrigerants reduces environmental impact and supports compliance with evolving regulations
