Self-heating and self-repairing fast door for low-temperature cold chain, opening speed 2m/sec.

Mistakenly hit door curtains are automatically repaired (returned) to normal working condition, saving you additional repair costs and time.

Thermal insulation door curtain material: the use of strong pressure forming within the folder mesh high-strength fibre PVC-coated cloth, single-sided thickness of 0.9mm, the total thickness of 10mm within the tuning punch thermal insulation cotton, can be effectively and efficiently isolate the exchange of airflow inside and outside of the cold storage and flow, airtight thermal insulation. Anti-static, flame retardant, high abrasion resistance, non-toxic.

Aluminium alloy/stainless steel rail built-in heating system and self-heating high quality imported motors can melt ice efficiently to ensure that the door opens freely.

The box and side panels are made of once-formed high-strength aluminium alloy, corrosion-resistant, neat and beautiful.

Adopting optical limit switch, the limit is accurate, safe and reliable.

Sealing properties.

The pvc base has a double-row nylon brush sealing structure for more effective insect and dust prevention. The bottom adopts EPDM air sealing structure.

Anti-freeze function.

Both sides of the track are equipped with a heating tape insulation layer, which is used in the contact area between the track and the door curtain to prevent icing and to ensure that the door operates normally.

Safety performance:

• 1, Infrared safety protection:Installed in the two sides of the infrared radiation device, when there is an object below the door, so that the door to remain in the open state; the door body down if there is an object through the door, the door automatically open to open the door position, the object passes through the thick and then delayed descent.

  2, Bottom safety protection edge:When the door is descending, if the object is in the blind zone of infrared safety protection, when the airbag at the bottom of the door touches the obstacle below, it will quickly rebound to the open position, which effectively protects the object below or pedestrians to avoid accidents.
