A green plant for refrigerated logistics in the heart of Lombardy
Like in The Betrothed, we are once again on the shores of Lake Como, but instead of villains, we find cold storage rooms, electrical panels, and CO₂ gas coolers.
Final Customer’s Need
The customer, already equipped with an initial part of the facility, decided to continue the expansion by choosing CO₂ technology—a sustainable, efficient solution perfectly aligned with the environmental goals of Stefani Spa.
Plant details
The refrigerated structure covers approximately 25,000 m³, divided into fresh and frozen storage rooms, processing and packaging laboratories, and areas dedicated to handling and shipping.
Installed power capacity:
Installed products
To support the system, 46 CO₂ air coolers have been installed:
The setup is completed by a powerful OSTRO C 90 EC gas cooler, featuring K65 coils and AISI 304 manifolds, capable of dissipating up to 1 MW of thermal energy under hypercritical conditions thanks to high-efficiency electronic motors.
Why Choose CO₂?
The transition from R407F to CO₂ was not just a technical decision but a strategic one as well.
The benefits are clear:
Reduced costs associated with fluorinated gases
Lower environmental impact
Easier maintenance, with long-term cost savings
Compliance with F-Gas regulations
The word to the costumer
Reliability and competitiveness were the main reasons for the choice. The confirmation? The customer opted for Stefani machines once again for this second phase.
“Once again, we chose Stefani for its build quality and performance consistency. The support we received and the facility’s efficiency reaffirmed our decision.”
