Why Teledoor
The Teledoor design offers quality construction for years of trouble-free service, resulting in low maintenance and easy repairs when required. The heavy duty construction provides proven reliability and performance for high-use applications.
The space-saving, energy-conserving Teledoor has an attractive appearance with its high-quality, two-coat baked acrylic finish over embossed, galvanized steel. By stopping air infiltration in winds up to 25 mph, Teledoor offers significant energy savings over competing brands.
Advantages in low maintenance costs
Teledoor has removed the major causes of maintenance and replacement costs by eliminating expensive counterbalancing springs, multiple hinges, pivot joints and roller guides used in other industrial doors. The door is the only one of its kind found in the industry.
Maintenance required on a Teledoor is simply periodic inspection, adjustment of the magnetic brake and lubrication of cables, chain coupling and operator controls.
Designed for easy repair and minimal operation disruption
Repairs to damaged panels can be made with relative ease and speed, usually by the owner’s maintenance staff. Damaged panels can be easily removed, repaired and restored to service with minimal downtime, and severely damaged panels can be made serviceable until replacement panels arrive.
In-house testing simulated an accident by driving a forklift into a door curtain as it was opening. Even though the impact dislodged the curtain from the side guides and severely dented several panels, the curtain continued upward to the fully open position. Other vertically opening doors do not have this capability and would normally have been rendered inoperative by such impact, blocking opening to traffic. Clearly, the design of Teledoor enhances the probability that the door will continue to function after such an impact.
Space-saving advantages
The compact unit requires little space allocation, allowing for traveling cranes and other types of overhead equipment. The standard, left-hand mounted, inheader door operator provides for minimal jamb and head clearances.
Energy-saving advantages
Favorable energy-saving ratings were earned in full-scale tests by independent agencies. Thermal transmittance tests per ASTM C-236 yield a 0.51 U-Value. Air infiltration tests per ASTM E-283 show superior draft exclusion, with leakage limited to 0.93 cfm/lin. ft. of perimeter, and no air leakage through the curtain at 25 mph wind load.
