V ertical 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.

When a heater cable dies, the result can build up over a long period of time. This picture is the result of years of ice build-up on a freezer door in a restaurant walk-in cooler/freezer combo. Even inside a cooler, a dead heat cable built up this much ice by blocking the freezer door open and accelerating the blockage over time. The energy waste expense is now far greater than the cost of a heat cable replacement, let alone the loss of product quality for the restaurant.
