• NEMA-4 Motor with frequesncy inverter providing maximum opening speed of 75″ per second and 30″ per second to close (depending on door size)
• PVC insulated curtain resistant to extreme temperatures -30˚C to +40˚C (-22˚F to +104˚F).

TNR’s line-up of high speed roll-up doors includes a rapid roll-up door which can sustain temperature ranges from +0ºC to -20ºC (32ºF to -4ºF) suitable for cold rooms, chill rooms and freezers. Fast reaction system minimizes temperature losses in cold rooms when door is open thus providing substantial savings in energy consumption. Ice build-up is avoided on components and walk-through areas. This door is ideal for the industrial sector including food processing facilities (meat, fish, packaging) and logistic services. Mechanical Components PVC insulated curtain resistant to extreme temperatures -30ºC to +40ºC (-22ºF to +104ºF). • Guides are anodized extruded aluminum with EPDM profiles to achieve better insulation
