Single Vertical Slide Doors

LoTemp vertical lift doors perfectly suit applications with limited side-slide space—typically the case in refrigerated loading docks and narrow corridors. The vertical slide doors are adaptable to both interior and exterior contexts and are available in standard sizes. Interior installments require adequate ceiling height for door lift.

LOTEMP Features

Standard Features

Steel and HDPE frame

LoTemp sliding doors are clad with 26-gauge white stucco embossed steel interior and exterior over an aircraft-grade anodized aluminum internal frame, with reinforced mitered corners. Sliding doors are insulated with a minimum of 4” of R32, non-CFC foamed-in-place polyurethane foam insulation.

LoTemp sliding doors also feature a wood-free design with the use of white HDPE (high density polyethylene extrusion) for the header, casings, jambs and mirror image backframes. Wood creates multiple adverse conditions because of warping, swelling, rotting, and the harboring of bacteria, molds and fungus. Use of wood in cold storage doors can lead to problems maintaining a good perimeter seal and passing critical health inspections. HDPE is a maintenance-free solution that provides exceptional resistance to moisture, fading, insects, splintering and warping. Consistent density and no voids in the material eliminates the possibility of bacteria, molds and fungus growth and creates a strong durable frame. HDPE has no wood fillers and high color stability. The strength, durability and overall appearance of HDPE means no additional steel cladding of the frame is required.

Adjustable bulb seals and bottom door sweep

Adjustable reinforced neoprene bulb seals are mounted on all LoTemp sliding door casings and header for a positive seal, correcting wall irregularities. The bottom of each door has a sweep sill of grease-resistant reinforced gasket.

Grooved-wheel track system

An aircraft-grade anodized aluminum track holder, with a “V” grooved wheel on UHMW triangle down and in-door track system, creates a positive seal at the frame and floor of each LoTemp sliding door. Combined with a carrier that incorporates a heavy-duty, non-derailing system, and an angle bracket, this track system provides users with a sturdy and reliable door operation. Floor-mounted stayrollers protect LoTemp sliding doors from damage and limit operation.

Exterior/interior handles

All LoTemp sliding doors are equipped with an exterior bow handle and interior recessed handle as a standard.

Heater cables (freezer models)

LoTemp sliding freezer doors feature full-perimeter heater cables in the door, ready for connection to a 120V/60Hz, single-phase AC line. The heat at the bottom of the door in conjunction with the four-sided bottom gasket creates a warm “chamber” under the door which eliminates the need for in-floor heaters.

Dual-speed operator, chain, and controller (power models)

LoTemp power sliding doors feature a dual-speed operator, requiring connection to 110V – 575V, 1 phase, 60 cycle (with one leg of 3-phase capped). Each power door operator uses a brushless technology motor which is totally enclosed for life. Chain adjustment assembly for a #40 roller chain is standard on all power door models.

Power doors additionally feature a controller with overload protection, providing smooth, quiet operation with programmable acceleration and deceleration, as well as programmable obstruction-sensing. The NEMA 4 control box operates sliding doors at an average speed of 30” per second per panel to open and 18” per second per panel to close. Two remote pullcord switches operate open/close controls.
