SINGLE HORIZONTAL SLIDE DOORS

APPLICATIONS
Clark SHS doors are the most popular of Clark's cold storage line. Primarily used to provide rapid access to cold storage, processing or other temperature critical areas where side room is not a problem. These doors are ideal in high traffic areas and can be used in interior or exterior applications.

CONSTRUCTION
Face Mounted Frame:
Vertical casings and header are Arctic white reinforced pultruded fiberglass. Casings and header are factory drilled and marked for rapid field assembly and perfect alignment.

Panel:
Door panel is constructed with 18 Ga. #304 2B stainless steel perimeter channel, joined at corner sections with aluminum-magnesium cast corners, and clad with 26 Ga. G-90 galvanized steel, white painted with non-directional stucco embossed pattern. Finish paint to be Imperial white modified polyester with a dry film thickness of 1.0 mil inclusive of primer coat. All seams to be sealed. Meets FDA, USDA-MID and Agriculture Canada requirements.

Track:
Duo-wedge double "J" track and hardware factory mounted on header. Door glides down and in on inclined track for positive seal and immediate clearance of gaskets when opening. Double "J" track prevents door panel from lifting out of position.

POWER DRIVE
Model 10000:
TEFC fractional HP synchronous AC motor coupled to 20:1 worm gear in oil bath totally enclosed for life. Adjustable, precision machined torque limiter designed to slip on overload only. Smooth, quiet operation with "soft" start and stop. Operates at average speed of 20 inches per second. (2) remote pullcords for open/close controls. Control voltage 24 vac. Entire system NEMA 4 standard. Full height, instant reverse safety edge - non-electric. Drive chain to be fully enclosed in galvanized steel drive track. Manual safety release.

Insulation:
Clark doors are filled with environmentally friendly, NON-CFC polyurethane insulation "R" - 7.8 per inch that provides outstanding strength and rigidity to the door as well as excellent thermal and acoustical performance. The insulation is injected to fill the door without voids. Steel facings are chemically fused to the insulation to provide vapor tight construction.

Features:

• Manual safety release.
• Adjustable, grease resistant, reinforced bulb type seals on perimeter
• Freezer doors are heated at gasket areas to prevent freezing.
• 4-wheel trolley assembly provides long wear on track.
• Instant reverse full height safety edge.
• Enclosed drive chain and sliding shoes.

CONTROLS

• Pullcord control is standard supplied with heavy duty cast aluminum 24 vac switches (heated inside freezer application).
• Time delay option available to automatically close the door.
• Induction floor loops are available to automatically reverse the door if the opening is obstructed or to automatically close the door after the traffic has passed through.
• Radio and infra-red controls are available as a vehicle operated system of door control.

Let us help you select the right operator and control sequence for your application.

Model 10000: Single speed at 20 inches per second (ips).
Cobra™: High speed- up to 60 ips.
Cobra™-DS: Dual speed.

Clark Door operators are designed to operate under heavy load and provide years of trouble free service.

All operators are supplied NEMA 4- water tight and dust proof for harsh environments - perfect for wash down areas. Precision ground shafts ride in sealed bearings. Motors are protected by thermal overload relay. Doors disconnect easily from drive when required.

Pullcord open/close control is standard. Installing the correct control sequence will facilitate traffic and protect the door. Pushbuttons, radio control, timers, floor loops, keyed switches, motion detectors, proximity sensors can be incorporated to provide the smoothest, fastest, safest control sequence for your application.
