AMTR Freeze 2 - High-Speed Double Curtain Freezer Door

Intended use

AMTR Freeze 2 is a high-speed self-repairing roll-up door with a double curtain system, designed for extreme freezer environments where maximum thermal insulation and stable separation between temperature zones are critical. With opening speeds of up to 1.5 m/s, the door ensures efficient traffic flow in high-performance cold storage and logistics applications.

The system features a self-repairing double PVC curtain that automatically reinserts into the side guides after accidental impact, minimizing downtime and ensuring continuous operation in demanding conditions.

The double curtain construction, combined with an internal air layer, provides advanced thermal insulation with a U-value of approximately 1.4 W/m²K. This significantly reduces heat transfer and supports stable operation in environments with temperature differences of up to 40°C between zones.

To prevent ice formation and condensation, the door is equipped with an integrated heating system including heated guides, motor heating and control cabinet heating, as well as air drying support. This ensures reliable operation even in extreme low-temperature conditions down to -35°C.

Powered by a 3-phase motor with active brake (IP55) and controlled via a logic system with inverter or contactor configuration, AMTR Freeze 2 ensures precise and stable movement. With maximum dimensions of 4500 × 5600 mm and wind resistance up to Class 3 (EN 12424), the door delivers consistent performance in industrial applications.

Equipped with a dual IP67 multibeam safety barrier and double anti-jamming sensors, AMTR Freeze 2 complies with EN 12604 and EN 12453, ensuring safe and reliable operation.

AMTR freeze 2 curains

The AMTR Freeze 2 curtain is designed as a double-layer system for maximum thermal insulation and reliable separation between temperature zones. It is engineered for intensive use in extreme freezer environments.

Curtain types

The standard curtain consists of a double PVC structure (900 g/m², 0.9 mm each layer) forming a double curtain system with an internal air layer.

This configuration provides thermal insulation with a U-value of 1.4 W/m²K, ensuring stable performance in freezer environments with temperature differences.

This version is designed for food industry applications requiring compliance with hygiene standards.

The double PVC curtain is approved for food use while maintaining the same thermal performance of U = 1.4 W/m²K, ensuring safe and reliable operation in hygiene-sensitive environments.

The anti-static curtain is designed for environments where electrostatic discharge must be minimized.

It features a reinforced PVC structure (1700 g/m², 2 mm thickness) with improved durability and a thermal performance of U = 1.39 W/m²K, making it suitable for demanding industrial applications.

Control

AMTR Freeze 2 is equipped with an advanced control system based on a logic board with inverter or contactor configuration, depending on door dimensions. The system ensures precise, stable and reliable operation even in extreme low-temperature environments.

Pre-wired plug & play installation simplifies setup, while adjustable parameters allow optimization of door performance for specific operational conditions.
