NeoCharge helps Sofrilog expand cold storage and freezing capacity without adding NH3 charge

  • Monday, 10 March 2025

Unlock greater capacity

Discover how Sofrilog, a leader in logistics and refrigerated transport, expanded their cold storage and freezing capacity without increasing ammonia charge. With NeoCharge, Sofrilog achieved innovation in refrigeration efficiency, ensuring compliance and cost-effectiveness.

Read the full case story

The NeoCharge sensor was easy to install on the existing evaporators and makes it easy for us to understand how each evaporator is performing. With the complete system retrofitted to NeoCharge, we can add a new freezer to our daily production and enlarge the cold room running overnight. This is the most effective way to realize our production expansion plan while using the present charge.

About Sofrilog

Headquartered in Normandy, France, Sofrilog specializes in logistics and refrigerated transport across Europe and Morocco. As a family-run business, Sofrilog delivers tailor-made solutions to the cold storage and food processing industry, consistently seeking innovative technologies to enhance their systems.

The challenge

Sofrilog aimed to expand the cold room and freezing capacity of their ammonia-based refrigeration system at a nearby brioche factory. The goal was clear, to increase capacity while keeping the ammonia charge below 1.5 tons, minimizing costs and maintaining performance.

The solution

Sofrilog partnered with Danfoss to retrofit their system with NeoCharge injection control. This involved upgrading five air coolers and four freezing tunnels with ICM20B electronic valves and EKE450 controllers. The result is a system with reduced recirculation and optimized charge control, enabling expansion without additional ammonia.

The result

With NeoCharge, Sofrilog can add an extra freezer with the same capacity, using saved ammonia to expand the system. The system delivers optimized performance with a continuous control of circulation rate improved cooling efficiency, with air temperature reduced by approximately 1°C. Lower cold room temperatures overnight reduce electricity costs, maximizing energy efficiency.
