Assa Abloy/Albany RR300 Chiller cold storage door

**Technical Specifications of Assa Abloy/Albany RR300 Chiller Rapid Roll Door**

**Heat Loss Seal**
When the door is closed, the seals on the top frame and the sliding rail prevent heat from escaping and maintain the required temperature.

**Climatex Insulation Curtain**
Made from high R-value insulation material for superior thermal protection.

**Heated Sliding Rail and Optional Blower Mode**
The sliding rail, made from aluminum, includes a 12V heating element to prevent frost or ice build-up. An optional air blower can be added to reduce condensation and prevent ice formation on the floor.

**Safety Features**
The door is equipped with electrical safety sensors and infrared sensors to prevent closure when obstacles are detected.

**Infrared Sensor at the Bottom Bar**
The sensor detects obstacles like goods or people and immediately returns the door to the open position.

**Top Roll Design**
The RR300 Freeze features a large diameter top roll for smooth operation, improving efficiency compared to older roll designs.

**Drive System**
Custom applications can include additional safety devices. Communication devices such as infrared sensors, radar detectors, push buttons, electromagnetic loops, or radio transmitters can be integrated into the control system, allowing for customization based on needs.

**Frequency Inverter Control**
Assa Abloy MCC technology is used for control systems, featuring a graphical interface and keypad. Diagnostic messages and troubleshooting information can be viewed directly on the screen.

**Impact-Resistant Bottom Bar**
The bottom bar is designed to automatically reset after a collision, protecting against damage and injury.

**Door Design**
Designed for maintenance and operation in extreme temperatures, the Albany RR300 Chiller minimizes energy loss and maintains a cold environment to ensure product quality.

- The Climatex insulation curtain is made from three layers of polyethylene insulation. Infrared sensors maintain and control the climate between normal and temperatures as low as -25°C or lower.
- The seal system reduces energy loss and controls the climate, unaffected by the surrounding environment.
- Low voltage operation for energy efficiency, with an air flow temperature control system.

**Fast Speed**
Ideal for high-traffic areas, the RR300 Chiller features quick and safe opening speeds to enhance productivity.

- Opening speed up to 3.3 m/s maintains cold storage temperatures.
- The impact-resistant bottom bar allows automatic reset after unexpected collisions.
- Slim sliding rail design, just 89 mm from the wall, saves space.

**Safety Assurance**
The RR300 Chiller incorporates reliable safety features to protect workers and products while improving performance in high-traffic areas.

- Soft, padded bottom bar automatically returns to the open position when encountering obstacles.
- Wireless safety system eliminates coil cables, reducing maintenance costs.
- Safety light grid – an infrared beam 1.8 m high across the door. If an obstacle disrupts the beam, the door automatically returns to the open position.

**Remote Monitoring Control**
Assa Abloy’s remote monitoring service offers additional protection for cold storage environments, allowing you to oversee door operations remotely.

**Drive System**
The drive unit is a braking motor reducer, which can be mounted on either side of the door.

**Control System**
A standard MCC frequency converter is provided.

**Manual Activation**
In the event of a power outage, the door can be manually operated using an emergency crank. Alternatively, a UPS can be installed to allow automatic door opening.

**Safety Devices**
The door is equipped with safety devices for both the product and users. Given the harsh environmental conditions, proper use might be impacted over time, and specific situations should be evaluated by an expert.
