Ai Fu special cold quickly spiral industrial doors

Germany Ai Fu (EFAFLEX) are imported refrigerator door complete system: with insulation, cold, insects, wind, dust, noise, fire, anti-odor, lighting and many other features, make sure you have high quality requirements. Using worm reducer: Good structural insulating envelope performance, styling and beautiful novel, compact advanced structure, easy to operate, durable, rigid, sealing, and (heated door seal design, no frost, no condensation) can be maintained at 30 degrees below zero speed on and off, effectively blocking airflow exchange, the annual festival refrigeration costs thousands of dollars. Hoist flexibility is the best choice for medical, cold storage. Products since 13 years running, never fails phenomenon has never been linked command is not executed phenomenon. Speed: TK-100 designed for industrial applications tailored uninterrupted use: Turn speed 2.5m / s, the closing speed of 1.0m / s door Material: double insulation for steel (hot dip galvanized), the standard height of 225mm internal filling polyurethane insulation material, thickness 200mm inside and outside handle connected by bridge, insulation coefficient 0.91-1.52w / m2k (in line with DIN EN 13241-1 standard). Top of the door at both ends of the drive shaft for the patented anti-wear product received spiral track, after the top of the door panel volume between the door no contact, no friction, no wear, the hole above the closing volume way round. High-strength spring system: Always make the door in to accompany the steady state, the transmission mechanism 250,000 times maintenance.
