Key Features
- Insulated curtain (two layers of PVC-coated polyester with a polyester weave and conductive plus radiant insulation) helps prevent heat loss and condensation
- Thermally broken, actively heated Thermoguides keep a uniform temperature along the full guide height for smooth door movement
- Quad-sealed, insulated guides with quad brush seals prevent guide condensation and loss of conditioned air around the curtain
- Ambient or heated air curtain, depending on the application
- Opens at up to 80″ per second and closes at up to 40″ per second
- Self-resetting breakaway bottom bar resets from either side of the opening after accidental forklift contact
- Springless design with a direct-mounted gear drive and variable frequency drive for smooth starts and stops and minimal maintenance interruptions
