Sliding Plenum

Side Sliding Paint Booth
Flexibility:
Our plenum side sliding hangar door systems are available in many
configurations to meet your specific requirements. Having built side sliding
plenum door systems over 80' tall, hundreds of feet in width, with wind speeds
up to 200mph, we are confident that we can build a system that will meet your
requirements and your imagination.

Design:
Doors are designed using CAD and structural engineering software. Door
frame structure and connection designs are certified by an independent
engineer. Door frames are engineered using structural steel and cold formed
members per AISC and AISI codes. Door frame members adjacent to plenum
airflow feature structural steel tubing and steel pipe to reduce air turbulance and
drag.Wind loads are calculated using your location and building size for the
most accurate structural loading possible. We don't make an assumption on the
wind load by using an arbitrary standard, we check every time.

Construction:
Door components are manufactured to the highest standards and designed to
be completely bolt together, avoiding costly delays due to welding inspections
and the availability of certified welders in the field. Door components are also
designed to have as few connections as possible, simplifying and increasing
assembly speed on the job. This lowers the total installed cost for your door
system.

Support Wheels:
Our support guide wheels are machined in house on CNC lathes and
assembled using taper roller bearings to transmit the vertical forces imposed
by the weight of the door and the lateral forces imposed by wind and seismic
loads. Support wheels are supplied with grease fittings installed on the support
axles and taper bearing adjusters. Support wheels can be removed from the
door panel through the top of the wheel box, allowing bearing/axle maintenance
without having to remove the door from the track.

Top Guide Wheels:
Door top guide wheels are equipped with permanently lubricated roller
bearings to ensure long life and low maintenance requirements. Door top guide
wheels are mounted on a telescoping guide bracket that will expand and
collapse to absorb differences in guide rail height due to live and seismic
forces exerted against the building. Top guide bracket can be made to absorb
virtually any building

Drive System:
Drive motor(s) is installed onto a mounting plate that is adjustable for chain
tension. Drive motor has a worm gear drive gearbox and is equipped with a
motor brake that is directly mounted to the drive motor. Chain drive features an
overload clutch to prevent damage in the case of overloading. Overload clutch
is easily released, allowing manual operation in the event of a power failure.

Weatherstrip:
Weatherstrip is 1/8" cloth inserted epdm. Weatherstrip meets military
specifications for durometer, UV resistance and incidental exposure to paint
thinners. Plenum doors are designed with dual weatherstrip seals for an air
tight seal from the door to the building or paint booth. Retainer bar is fastened
by zinc coated self drilling screws every 8" for a secure seal without oil canning
of retainer bar. Retainer bar is easily removed for replacement of
weatherstripping if it becomes necessary. Leading edge bubble seals alow for
4" of compression.

Electrical Controls:
Door control panels are manufactured in house using only the highest quality
UL listed components. Door control systems utilize electromechanical relays
that are highly resistant to electrical interference and have no programming that
can become corrupted requiring service. Door control systems also utilize solid
state proximity sensors for limiting door travel. These sensors are water proof
and have no moving parts to wear out. Door control systems can be supplied
ranging from 12VDC to 600VAC. Variable frequency drives are available for
custom tuning or varying of door drive speed. Variable frequency drives come
with variable speed buttons with 3 adjustable speed settings standard, 5
speeds as an option. Door controls that are inside the paintbooth area are
installed into an explosion proof electrical enclosure. Drive motors located
inside the paint booth are supplied standard as Class 1, Div 2 hazardous
location approved. Class 1, Div 1 available upon request. Included with plenum
doors are the necessary rigid conduit and seal-offs to make a complete
hazardous location compliant installation.

Power Feed:
Standard power feed system supplied is a drape cord design. With no trolleys
to wear out or become tangled a drape cord system offers many years of
trouble free service.

Standard options:
Timer delay with safety noisemaker and/or strobe light, safety edge with delay
and/or auto reverse, personnel door frames and safety interlock sensors,
bumper door collection system, cable drive door collection system, explosion
proof drive system, air drive operating system, hydraulic drive operating
system. Door drive motors and control panels are fully assembled, wired and
tested at our facility prior to shipping.

Please call with your custom option requirements, we are here to create the
system that meets your needs and your imagination.
