The most important function of a cold storage door is to reduce cold air leakage for energy savings. After years of cold storage door usage testing in Europe and America, the following three points are the most important for energy loss in cold storage:
Since 1987, the DYNACO FM2 high-speed cold storage door has maintained a "zero accident" record. The absolutely soft bottom edge ensures complete safety of DYNACO high-speed doors. The world-patented rack and pinion drive technology means the door closing process no longer relies on the traditional weight of the door bottom edge. The curtain surface has no hard materials, ensuring complete protection of pedestrians and goods when the door closes at high speed. Especially in cold storage working environments, high-speed closing prevents indoor and outdoor temperature exchange and achieves energy savings. In addition, every DYNACO high-speed door comes with photoelectric protection and wireless anti-pinch function at the door bottom, providing multiple safety guarantees for the customer's working environment.
The soft high-speed cold storage door safety has passed EU CE standards, standard number: EN12453, test number: EN12445. The complete self-repair function is DYNACO's signature global patented technology: every FM2 high-speed cold storage door is equipped with a derailment automatic repair system. Even when the door is hit, no manual restoration is needed, minimizing downtime and maintenance costs.
The FM2 high-speed cold storage door uses the world's most advanced door edge rail technology to achieve high sealing performance, reducing heat loss for maximum energy savings, while abandoning traditional blade and brush sealing systems. The curtain zipper closely combines with the guide rail to completely eliminate gaps, achieving true sealing in design and preventing air inflow and outflow.
The FM2 high-speed cold storage door is installed with anti-freeze heating cables in the slide rails on both sides, and an insulation device in the control box, completely eliminating icing problems in the slide rails and greatly extending the door's service life. The door body anti-freeze heating wire has low power consumption and a service life of over 15 years.
The FM2 cold storage door opening speed is 2.4m/s, closing speed is 1.2m/s. The world-patented rack and pinion technology not only ensures extremely high opening speed, but the 1.2m/s closing speed is the highest closing speed in the cold storage door industry. Tests show that at a cold storage temperature of -25°C: for two 3m×3m high-speed doors with the same opening speed, the one with 1.2m/s closing speed saves nearly 10,000 yuan in electricity costs per year compared to the one with 0.8m/s closing speed.
Soft cold storage door, EU standard class 1, up to 300 Pascal; standard number: EN12424; test number: EN12444.
The service life of DYNACO high-speed cold storage doors is at least 1 million closing cycles, and some have actually reached 7-8 million cycles. Based on daily usage frequency of 700-800 times, the lifespan of DYNACO cold storage doors is at least 5 years.
The powerful self-detection control system and rich interfaces for expanding functions can maximally meet customer needs for different control functions and automatic functions of the door. All functions are programmed into the PLC via computer, featuring high performance, high reliability, high stability, and high-precision positioning. It also has soft start and slow stop functions, ensuring smooth door operation and extending service life. With built-in fault recovery function, the system automatically recovers 10 seconds after power is restored. The control box can be installed inside the cold storage door. The DYNALOGIC control box is equipped with open/close buttons, emergency stop switch, and a power switch. Protection rating: IP54.
The DYNALOGIC III control system can simultaneously interlock up to 16 DYNACO high-speed doors. DYNACO will develop customized solutions based on customer requirements.
The inverter-driven motor ensures smooth and stable door operation. This technology ensures slow start and slow stop of the door, greatly extending the motor's lifespan. The protection rating of the DYNACO FM2 high-speed cold storage door operator is IP65, and it can work at -35°C low temperature.
To better improve the energy efficiency of the FM2 cold storage door, customers can choose insulated curtain material. This curtain has a PVC surface layer with insulation material filled in the middle, significantly reducing heat transfer on the curtain panel.
