Ageing fans threatened HACCP compliance
Food processing facilities require unwavering cold chain integrity. When 25-30 year old fans fail, temperature fluctuations compromise HACCP compliance and spike energy costs.
CS Gruppen A/S operates Denmark's largest food logistics network. Their Padborg facility processes 250-300 tonnes daily, handling 200,000 pallets per year. The facility freezes fresh meat at minus 30 °C and maintains storage at minus 18 °C for global distribution.
Facility expansion required immediate ventilation upgrade to maintain food safety standards while controlling operational costs.

Technical solution details
The freezing tunnel operates in four sections, each handling 100,000 m³/h air volume. This design enables rapid meat freezing using layered gratings with optimised airflow for maximum cooling efficiency. The controlled environment maintains precise conditions essential for preserving product quality throughout the freezing process.
The installation delivers reliable performance through carefully specified components. 4 ZerAx AZL-900 fans each deliver 25,000 m³/h, providing the air volume required for effective operation. HACCP compliance comes from consistent temperature control, while adherence to food safety standards ensures reliable cold chain maintenance. Energy optimisation reduces operational costs without compromising performance.
Proven performance in extreme conditions
The ZerAx® AZL-900 installation at CS Gruppen demonstrates proven performance in extreme cold chain environments. With 4 fans each delivering 25,000 m³/h, the system maintains precise temperature control essential for food safety standards while achieving 90% efficiency with IE3 motors rated for -30 °C operation.
