Sérifroid Tunnel de surgélation SG900 Tw

Serifroid SG900 Twin Spiral Freezer Tunnel

The Serifroid SG900 Twin spiral freezer tunnel enables continuous quick-freezing with high consistency, while preserving product quality. It is suitable for production facilities seeking stable throughput and precise temperature control. Thanks to its twin-tunnel design, air circulates evenly around the products. This ensures a controlled temperature drop from start to finish of the cycle. Such control improves final texture, minimizes water loss, and guarantees a consistent appearance for every batch.

The stainless steel conveyor belt ensures smooth product transfer. In addition, the 80-mm polyurethane foam insulation significantly reduces thermal losses, enhancing energy efficiency. The system operates with CO₂ (R744) refrigerant, delivering excellent thermal performance while meeting environmental requirements. The SG900 Twin is equipped with automated regulation, allowing freezing parameters to be maintained without constant supervision. Operators only need to intervene to adjust recipes or throughput, simplifying operation.

Defrosting is quick and scheduled. In fact, a 20-minute cycle every 8 hours is sufficient to maintain freezer tunnel performance. This reduces downtime and supports continuous operation. Furthermore, the freezer unit can be easily integrated into existing lines, whether in bakery, meat processing, or ready meal production. The process consistency enhances overall efficiency while securing final product quality. The SG900 Twin is therefore a strategic investment for workshops aiming to increase capacity while ensuring stable, repeatable freezing results every day.
