The Reliable Cold Remedy.The Fast-Fold® Freezer door gave birth to the idea of high-speed doors in cold storage environments-- and the rest is history. It was the very first door to be used in cooler and freezer applications, and its time-tested durability and dependability have made it the best selling high-speed door for cold storage environments. Your choice of three different defrost systems assures your Fast-Fold Freezer door will remain virtually frost free, whatever the nature of your cold storage application.
FastOpens at up to 84 inches per second for improved traffic flow.
Threshold SafetyWith its full height, clear PVC panels, the Fast-Fold Freezer provides great visibility and added safety for interior applications where fork trucks and other equipment are crossing the threshold in both directions, crossing the door’s traffic lane, or both.
Energy EfficientInsulated head and side frames, along with sealed panel assembly, combine with fast opening and closing speeds to reduce energy loss.
Virtually Frost FreeThree different defrost system options help reduce frost build-up.
Durable & Low MaintenanceEngineered to last million cycles with minimal maintenance.
Takes a HitWithstands fork truck impact with little or no damage, virtually eliminating door down time.
System 4™ Door Controller (Standard)Incorporating state-of-the-art motion control technology, the System 4 controller combines the flexibility and performance of AC Drive technology with the ease and precision of digital control.
ACTIVATORSThe System 4 door controller is designed to operate with many different types of activators, depending on the application and operating environment.
Floor Induction Loop (Optional)Activation loops embedded into the concrete on both sides of the doorway substantially reduce operator error in opening and closing doors. With no moving or exposed parts, floor induction loops are extremely reliable.
Motion Detectors (Optional)Motion detectors operate on microwave technology. They detect pedestrian and vehicle motion in a prescribed area. The detector sends a signal to the controller to open the door.
Presence Sensors (Optional)Presence sensors detect pedestrians and vehicles in the area of the detector. Motion is not necessary. The sensor signals the controller to open the door.
Radio Controls (Optional)A radio control consists of a transmitter and a receiver. The vehicle operator activates the transmitter which sends a signal to the receiver. The receiver then signals the controller to open the door.
Push Button (Optional)The push button is generally used with pedestrian traffic and is typically mounted on the wall near the door. Pedestrians push the button as they approach the door, which signals the door to open.
Pull Cords (Optional)The pull cords are switches mounted on the ceiling. Pedestrians and vehicle operators pull the cord as they approach the door, signaling the controller to open the door. Vehicle operators generally have to slow down to pull the cord.
Multiple Activators (Optional)The System 4 door controller permits many activators to be used in multiple combinations. For example, a door can be opened by forklifts through induction floor loops and by pedestrians through a push button, each with independent closing times to allow for pedestrians passing through the door.
Roller OptionsRyflex™ model GS (1-7/8 inch) rollers are standard. Other size Ryflex™ rollers are available, including G and BFGS.
Panel OptionsOptional overlapping panels with rope tie connectors available.
Optional Insulated panels available.
Defrost System OptionsThree different defrost systems are available to satisfy the vast majority of freezer applications. The systems help minimize frost buildup and maintain visibility.
Defrost Options Include:
AirlocksIn airlock applications, one controller with various activators permits doors to be interconnected so only one door is open at a time.
