CLEANROOM / PHARMACEUTICAL DOORS

APPLICATIONS
Environmental Traffic Control:
Clark Cleanroom/Pharmaceutical doors are designed for interior openings where frequent operation and maximum attractiveness are required for control of temperature, humidity, sound, dust and dirt. Perfect for clean rooms, pharmaceutical, processing areas and computer rooms.

CONSTRUCTION
Face Mounted Frame:
Vertical casings and header are Arctic white reinforced pultruded fiberglass, easy to clean, corrosion free and never need painting. 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 24 Ga. #304 2B stainless steel. All seams to be sealed. Meets FDA, USDA-MID and Agriculture Canada requirements.

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. Panel facings are chemically fused to the insulation to provide vapor tight construction.

Vision Panel:
The Clark vision panel comes with a standard view size of 30" x 36" safety laminate pane to provide maximum vision through the door. The vision frame is tapered to resist dust and for easy cleaning.

Track:
Double "J" track and hardware factory mounted on header. Double "J" track prevents door panel from lifting out of position. 4 wheel trolley assembly provides long wear on track.

Seals:
Grease resistant, reinforced knife type seals around the full perimeter of opening with "skirt" type seal on bottom or door panel. Concealed glide roller assembly holds the door tight to the frame when panel is closed.

Hood:
Tapered, low profile, full width 18 Ga. #304 2B stainless steel hood over track/operator.

Auto-Close with Hold Open Provision:
Manual doors are fitted with an adjustable tension spring closer to gently return the door to the closed position. Moving the door panel to the full open position will engage the hold open position, allowing the door to stay open until nudged out of the hold open state.

POWER DRIVE
Model 1000:
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 operation with "soft" start and stop. Operates at average speed of 20 inches per second. (2) remote pushbuttons 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. Electric overload protection.

Clark 9600 Hydraulic Operator - Single or Dual Speed
The Clark 9600 Hydraulic Operator is designed for rapid opening with the simplicity of hydraulics. The 9600 incorporates the Clark 10000 operator transmission and combines a 1 HP electric motor, hydraulic pump and control valve into one compact unit. High starting torque provides fast, smooth acceleration to a precise stop. The single speed unit operates at 25 inches per second per panel and the dual-speed at 60 ips to open and 30 ips to close.
