ENCLOSURES
A.
Frame Supported Hot Aisle Containment Enclosure (for all Cabinet Systems)
1. [Hot Aisle Containment Enclosure] Provide required components to enclose
the hot aisle between adjacent rows of equipment cabinets. The hot aisle
containment enclosure system shall include a frame supported overhead
exhaust duct that is independent of the cabinets to isolate and exhaust hot
air into an overhead drop ceiling or return ductwork, two Aisle Containment
Doors to seal both ends of the hot aisle, and individual cabinet to floor seal
kits to seal the space between the bottom of the cabinets and the floor. The
hot aisle containment enclosure system supports a closed return air path
within the data center or computer room.
2. [Frame-Supported Exhaust Duct] The frame supported exhaust duct shall
consist of metal posts and beams that construct a cabinet-independent frame
and translucent panels which connect together to form an enclosed overhead
duct. The frame shall have four corner posts with an open span between
posts that is 12 feet (3.6 meters) to 20 feet (6.0 meters) long for cabinet
rows. The beams over the cabinet rows shall allow a mix of cabinets up to
52U high to be placed within the rows and shall include a built-in 2” (51 mm)
vertical adjustment to level the beams. The frame will cover either 48” (1220
mm) wide two tile aisles or 72” (1830 mm) wide three tile aisles. The lateral
supports over the contained aisle shall adjust up to 16” (400 mm) in width to
accommodate varriances. Each exhaust duct panel shall be a translucent
polycarbonate panel that extends vertically 60”H (1524 mm) toward the
ceiling. The panels shall be attached to/between the lateral supports to form
a continuous duct over the hot aisle. The panels will be field fitted to the
ceiling height and shall be sealed at the top between the panel and the drop
ceiling to block bypass airflow. If cabinet heights vary, additional individual
panels shall be used to seal the space between the tops of cabinets and the
bottom of the overhead frame supported duct. If cabinets are omitted or do
not fill the entire space between posts, additional translucent, full height
blanking panels shall be used to seal the space(s) between cabinets.
3. [Aisle Containment Doors] The aisle containment door shall be a double
sliding door. The door frames and track shall be aluminum extrusion. The
center panels shall be a full-height, transparent polycarbonate material. The
doors shall have an auto closing mechanism and a magnetic seal, but shall
also detent open for easy access to the hot aisle during maintenance. The
REQUIREMENTS

doors shall be sealed on the top, bottom and sides when closed, and there
shall be no separate mechanical threshold under the door when opened.
Double-sliding doors shall open to 42” wide (1067 mm) and shall be sized to
span 48” to 72” wide (1220 mm to 1830 mm) aisles, two to three tile aisles.
Doors shall attach to the top of the cabinets with flush or offset brackets
(ordered separately) and will attach to the floor. Floor attachment hardware
shall be hidden within the door assembly. The manufacturer shall offer an
installation template and standoff panels as optional accessories.
4. [Cabinet To Floor Sealing Kits] The cabinet to floor sealing kits shall include
a front-mount and side-mount bracket with flexible sealing material sized to
match each cabinet. The cabinet to floor sealing kit shall be used on the front
and side of each cabinet that is elevated above the floor on leveling feet or
casters. The kit shall seal the space between the bottom of the cabinet and
the floor to prevent bypass airflow around the contained hot aisle. If the
cabinet manufacturer does not offer a specific sealing kit for the cabinet,
adhesive expandable foam tape or an adhesive foam panel may be used to
seal the gap between the bottom of the cabinet and the floor.
5. [Cabinet To Floor Sealing Kits] The cabinet to floor sealing kits shall include
front/rear-mount and/or side-mount brackets sized to match each CPI FSeries TeraFrame Cabinet or GF-Series GlobalFrame Cabinet. The cabinet
to floor sealing kit shall be used on the front/rear and sides of each cabinet
that is elevated above the floor on leveling feet or casters. The kits shall
combine to seal the space between the bottom of the cabinets and the floor
to prevent bypass airflow around the contained hot aisle.
6. [Material/Construction] The frame shall be steel and aluminum. The door
frames and track shall be aluminum extrusion. The door panel shall be
transparent polycarbonate material. The overhead ceiling panels shall be
translucent polycarbonate material. Components shall assemble with
hardware.
7. [Color/Finish] The metal components of the containment solution shall be
painted black with epoxy-polyester hybrid powder coat paint unless otherwise
specified. Aisle containment door frames may be clear anodized aluminum
extrusion or painted to match the cabinets.
Choose the cabinet color: black or glacier white
8. [Performance Specification] The Frame Supported Hot Aisle Containment
Enclosure shall be designed and tested to support a minimum of 3000 CFM
(5097 CMH) of exhaust airflow per cabinet. At .05 inH20 (12.5 Pa) of
pressure, the leakage will be less than 5%.

Communication Equipment Rooms
02/13/16
Chatsworth Products Inc.
1. Provide all components of the hot aisle containement enclosure (frame
supported exhaust duct, aisle containment doors, floor-to-cabinet sealing
kits) from a single manufacturer.
2. Install the frame supported exhaust duct using the manufacturer’s installation
instructions. The frame must be secure to the structural floor. The duct must
be field fitted to match ceiling height and secured to the frame. The duct must
be sealed between the top of the panels and the drop ceiling or overhead
exhaust ductwork.
3. Install aisle containment doors using the manufacturer’s installation
instructions. Doors must be secured to the frame that supports the overhead
duct (not the cabinets) and the floor. Installers shall provide appropriate floor
installation hardware as defined by local code or the authority having
jurisdiction (AHJ). Additional installation brackets or panels may be required.
4. Bay cabinets together side-by-side using baying kits and seal kits and/or
expandable adhesive foam tape to block airflow between cabinets. Each
cabinet should be equipped with an air dam kit and filler/blanking panels to
block front-to-rear bypass airflow through the cabinet/around equipment. Also
use raised floor grommets to seal openings in the raised floor to prevent the
loss of cold air.
5. Install full height blanking panels using the manufacturer’s installation
instructions. Full height blanking panels must seal spaces between cabinets
where cabinets are omitted or on the ends of cabinet rows if cabinets do not
fill the entire space between frame posts.
6. Install additional overhead filler panels using the manufacturer’s installation
instructions. Overhead filler panel must seal spaces above cabinets between
the tops of cabinets and the overhead duct.
7. Install cabinet to floor sealing kits around the base of the cabinets using the
manufacturer’s installation instructions or use expandable adhesive foam
tape or panels if no specific kit is available. When cabinets are elevated on
leveling feet or casters, the space between the bottom of the cabinet and the
floor must be sealed to block airflow under the cabinets.
