F. NETWORK MANAGEMENT CARD

The unit shall include a network management card to provide management through a computer network through TCP/IP. Management through the network should include the ability to change set points as well as view and clear alarms.

G.COOLING COIL AND CONDENSATE PAN

1. Chilled Water: Cooling coil shall use raised lance type corrugated aluminum fin and (12.7 mm (1/2 in) OD copper tube coils. Fin shall be a minimum of 0.0055 in thick. Tube wall shall be a minimum of 0.016 in thick. Coil tube sheets shall be a minimum 1.2 mm (18 gauge) G90 galvanized steel. Coil shall be rated for a maximum pressure of 2757.9 kPa (400 psig). Coil headers are equipped with drip plates in the bottom to route the condensate accumulating on the header tubes to the condensation pan. Coil is configured in a counterflow arrangement to optimize heat transfer efficiency.

2. Direct Expansion: Cooling coil shall use raised lance type corrugated aluminum fin and 12.7 mm (1/2 in) OD copper tube coils. Fin shall be a minimum of 0.0055 in thick. Tube wall shall be a minimum of 0.016 in thick. Coil end supports shall be a minimum 1.2 mm

(18 gauge) G90 galvanized steel. Coil shall be rated for a maximum pressure of 3447.3 kPa (500 psig), and the coils are certified in accordance with UL207. Coil header is equipped with a drip plate in the bottom to capture and direct the condensation accumulating on the suction header tube to the drain pan. Coil has 6 circuits complete with brass distributor and copper distribution tubes.

H.VARIABLE SPEED COMPRESSOR / VFD ASSEMBLY (AIR-COOLED ONLY)

1. Compressor: The unit shall be configured with a variable speed reciprocating hermetic compressor using a matched VFD. As a result, the compressor speed can be varied through a range between 30 and 85 Hz to accommodate varying load conditions. VFD firmware is written to include oil return protection in cases where pipe velocities may drop to low speeds during low loading periods.

2. Compressor is electrically protected through the VFD.

3. Compressor utilizes a noise cap for noise reduction.

4. Sight glass provided for air cooled system oil charging.

I.3-WAY MODULATING VALVE (CHILLED WATER ONLY)

1. A floating point valve shall be microprocessor controlled to automatically direct the proper amount of chilled water in the cooling coil to maintain desired conditions. A shut-off valve located in the bypass line may be manually adjusted for 2-way flow if so desired.

2. Three way control valve shall be rated for 300 WOG with brass body and stainless steel ball.

3. Valve Actuator: Actuator shall be direct connect rotary floating point style actuator with potentiometer feedback, and should be capable of being replaced without disconnecting piping from the valve. Ability for manual operation is also provided.
