Blower Unit: This is the core component responsible for generating a high-velocity airflow. The blower is usually equipped with powerful fans capable of producing a strong curtain of air. Heating Element (Optional): In some cases, especially in extremely cold environments, air curtains may incorporate a heating element to ensure the air blown into the cold storage area remains above freezing temperature, preventing frost buildup. Control System: Modern air curtains often feature intelligent control systems with sensors that detect door openings and adjust airflow accordingly. This helps optimize energy efficiency by activating the air curtain only when necessary. Mounting Hardware: The air curtain is typically mounted above the entrance of the cold storage area using brackets or suspension systems. Installation may vary depending on the specific design and requirements of the facility.
