Standard Components

A. CABINET CONSTRUCTION

1. Exterior panels shall be 18 gauge metal with 5 lb/ft

(80 kg/m

) density foam insulation.

Insulation complies with UL94-5VA ASTM E84 flame spread and smoke developed

rating of 25/50. Front and rear exterior panels shall be 18 gauge perforated steel with

69.5% open free area, and equipped with a keyed lock to provide a means of securing

access to the internal components of the unit.

2. The frame shall be constructed of 16 gauge formed steel welded for maximum strength.

All units shall provide full service from the front and rear, allowing units to be placed

within a row of racks.

3. All exterior panels and frame shall be powder coated for durability and attractive finish.

Exterior frame and panel color shall have color values: L = 74.50, a = -.53, b = +8.20.

4. Units shall include casters and leveling feet to allow ease of installation in the row and

provide a means to level the equipment with adjacent IT racks.

B. VARIABLE SPEED DIRECT DRIVE MIXED FLOW DC FAN ASSEMBLY

1. Fan: The unit shall be configured for draw-through air pattern to provide uniform air flow

over the entire face of the coil. Each unit shall include six 200 mm mixed flow direct drive

DC axial fans. Three fan assemblies shall be designed to provide 400 CFM (680 m

/hr)

each across the evaporator coil for total unit airflow of 1200 CFM (2039 m

/hr). Three fan

assemblies shall be designed to provide 283 CFM (480 m

/hr) each across the condenser

coil for total unit airflow of 850 CFM (1440 m

/hr).

2. Variable Speed Fans: Fans shall be variable speed capable of modulating from 30-100%.

Fans shall soft start to minimize in-rush current when starting.

3. Fan Protection: Each evaporator fan assembly shall consist of a plastic injection molded

bezel with integral fan discharge finger guard. Inlet of the fan should include a cage type

finger guard.

4. Operation and Service: The unit should be capable of operation in the event of a fan

failure. Evaporator fans shall be replaceable while the unit is in operation.

C. POWER SUPPLY

1. Input Power Feed: Single power input should be a locking NEMA or IEC plug connection

suitable for the input power selected. Unit power consumption is not to exceed 2950 watts

during normal operation.

2. Fan Power Supplies: Dual internal DC power supplies are capable of running all fans at

80% capacity in the event of a power supply failure. Power supplies shall be hot-
