RR300 Chill-Freeze (High-Speed Door for Cold Storage and Freezer Applications)

RR300 Chill and RR300 Freeze are high-speed doors equipped with essential features for cold and freezer storage applications, delivering reliable performance even in extremely low temperatures. These doors are specifically engineered to meet the unique requirements of refrigerated environments, preventing frost and ice buildup even after hundreds of daily cycles.
Constructed with advanced cellular insulation, they minimize condensation and ice formation around the door. RR300 Chill (for temperatures above 0°C) and RR300 Freeze (for temperatures as low as -25°C) include heated side frames and an energy-saving airflow system to prevent frost and condensation. Additionally, both models help reduce energy loss, lowering overall energy costs.

Minimizes energy loss by using Climatex, a special heat-resistant curtain.
With an opening speed of 3.3 m/s, it minimizes energy loss while preventing condensation and ice formation.
