Vertical Doors Offer A Tall Range Of Flexible Configuration

Vertical doors, with their wide range of styles, sizes, and options, meet the needs of many cold storage applications through the flexibility of their design.

Confined door openings are managed with ease since they require only minimal amounts of wall space to either side. Variations of door width allow for multiple door openings or special-use doors on the same wall.

Three different vertical door styles provide a design to fit the need. Full-lift doors move as a single rigid door, providing a highly secure and impervious shield between internal and exterior conditions. Sectional doors come in two styles, the standard height matching the door opening and a high-lift version that maximizes the clearance space inside the door opening by traveling as high as possible before turning back, a good fit between the clearance of a full-lift door and a standard sectional.

Vertical door placement and style is not the end of flexibility for vertical doors. Size presents another vector of flexibility. Standard door sizes run up to 12 feet by 12 feet, but larger sizes are engineered through the use of multiple panels and cam-locks that form larger door units. These larger than standard door units have the same rigidity, strength and temperature rating of any single panel.

Flexibility continues with a wide range of options.

Vertical doors can operate manually, mainly for smaller doors or doors that are seldom used, or powered lift at 18 inches per second. Powered lifts may be actuated by pull cords, radio control, motion detectors or loop detectors, determined by the facility needs. In freezer applications, the interior control panel is heated. All R-Plus powered doors include an air-activated instant reversing edge along the entire bottom length of the door panel. Track and operator are assembled and tested at the factory prior to shipping.

R-Plus sectional doors have easily replaced grease-resistant neoprene bulb-type seals and foam gaskets are placed between door sections. On freezer installations, all four sides of each panel are pre-wired with UL-approved heat cable, also completely replaceable, ensuring smooth operation that avoids freezing problems.

Windows are available in both heated and non-heated versions to match the application. The triple-pane windows are standard in 14-inch by 14-inch size, but other sizes are available by specification. Windows can be placed for safety considerations or for natural light collection.

Personnel doors are available with R-Plus full-lift doors. These doors allow quick passage for individuals, and even for small pallet jacks and other small wheeled tools. Using a small entrance for personnel access makes it easier to maintain the integrity of the interior environment, lowering energy usage and costs.

Door cladding is available in different gauges in baked-on enamel steel in a variety of colors; aluminum; and stainless steel for greater durability.

Configuration flexibility is the signature of R-Plus vertical lift doors. There are styles, sizes and options to match any need, ask Nick Stahl (1-800-238-4093) for his recommendations.
