The TECH-ROLLTMrubber curtain is available in SBR black rubber, MSHA black rubber (mining spec) and EPDM blue rubber. The rubber is 1/4-inch thick and reinforced with a polyester centre that ensures flexibility and durability in temperatures between -40°C and + 50°C. Its strength resistance is 2,000 psi.
Indotech’s TECH-LOCKTM are continuous the full height of the door to create a weather-tight seal. The system creates a frictionless movement of the door’s curtain within the guides when the door is opening and closing.
The bottom bar is made of steel and equipped at the center with a pintle hinge that allows the release of the curtain in case of impact, this ensures a fast and easy re-installation of the curtain.
The steel guide rails are designed with adjustable compression springs that allow the release of the curtain in case of impact and are ajustable to adapt to various windloads. In addition the guides can be opened for full inspection of the door’s curtain and ease of maintenance.
Wind bars are an optional feature that are used to reinforce the door’s curtain in locations that have severe weather conditions and/or exceptional wind loads.
The extra-strong coil springs (25,000 to 100,000 cycles) are mounted on the outside of the main C-channel cross member and assembled on a 1-1/4 inch (32mm) steel shaft.
The TECH-ROLL series of electric operators are high-performance industrial operators designed for intensive use and require minimal maintenance. They are equipped with a clutch system and the possibility of an over-sized brake that allow the door to run smoothly. In addition, the operators are equipped with a chain hoist and power safety switch in cases of emergency.
Optional protection system that prevents the door from closing in the event of mechanical failure. This security system is unique to Indotech
