Are you looking for a solution for your industry or do you have a technical problem that needs solving?
A modern distribution centre for food products now operates in the region, relying on advanced industrial refrigeration solutions based on CO₂ refrigerant. The complete cold store solution for the investor Inter Alfa was designed by the MB Frigo Grupa engineering team on a turnkey basis, from the first sketch to commissioning and monitoring during operation.
About the investor
Inter Alfa is a company specialising in the distribution and storage of food products. The daily rhythm is marked by high stock turnover: trucks come and go continuously, and every pallet of chilled goods must be at the prescribed temperature at all times. In such an environment, the cold chain becomes the foundation of the business – customer and supplier trust rests on it. That is why the investor set high requirements: uncompromising reliability, energy efficiency and full traceability of temperature regimes.
The challenge: 8 cold rooms, three temperature regimes, 24/7 operation
A refrigeration system that supports high daily stock turnover and fast handling between temperature zones: 8 cold rooms at +4 °C and −18 °C and a handling and loading area at +10 °C – in continuous 24/7/365 operation for the next few decades.
The solution: industrial refrigeration based on CO₂ (R744)
Multi-compressor CO₂ unit with redundancy
Several compressors share the load, so the failure of one does not stop cooling, and an independent backup unit takes over maintaining the temperature regimes during servicing or unexpected downtime.
Room within a room
A special feature of the project is the cold rooms with racking storage, built so that one chamber sits inside another with a different temperature regime. This maximises space utilisation and shortens handling routes. Sliding cold room doors retain temperatures overnight, while double high-speed roll-up doors allow forklifts to pass quickly during working hours. Goods flow fast – and the cold stays where it should.
CO₂ (R744) as a long-term decision
The environmentally friendly refrigerant enables energy-efficient cooling and a long-term sustainable solution in the context of the F-gas regulation, with a permanently low refrigerant price. Dynamic control automatically adjusts the cooling capacity to the actual needs of the warehouse, keeping running costs at an optimum.
24/7 digital monitoring
The system is connected to the Carel BOSS monitoring platform: remote control from any device, instant alarms at any deviation, continuous temperature logging and automatic HACCP reports. The MB Frigo service team sees the system before a problem becomes a problem.
Value for the investor
Stable storage conditions, full control over the cold chain and reliable operation with high stock turnover. The CO₂ system eliminates the regulatory risk of future restrictions on F-gas refrigerants, the backup unit ensures operational continuity, and digital monitoring turns HACCP compliance from an obligation into an automated process.
Frequently asked questions
Why CO₂ (R744) for industrial refrigeration of a distribution centre?
CO₂ is a natural refrigerant with a GWP of 1, exempt from F-gas regulation restrictions. With energy-efficient operation and a permanently low charge cost, it is a long-term safe investment without regulatory risk.
What does a "turnkey" solution mean in industrial refrigeration?
MB Frigo Grupa takes over the entire project: from needs analysis and design, through manufacture of the refrigeration unit and construction of the cooled space, to commissioning, staff training and ongoing maintenance and remote monitoring.
How does the system ensure an unbroken cold chain?
The multi-compressor unit with redundancy and an independent backup unit ensure continuous cooling even during servicing or failure, and the Carel BOSS platform logs temperatures 24/7 and automatically generates HACCP reports.
