USNS MILLINOCKET (T-EPF3) Bill of Material

The Maritime Administration, Suisun Bay Reserve Fleet (SBRF) is seeking to procure Dehumidification

Equipment for maintaining internal areas of the United States Naval Ship (USNS) MILLINOCKET in the

National Defense Reserve Fleet anchorage.

Provide the following:

3 EACH - Munters HCD-600 Honeycomb dehumidifier or equal. With rotating SIGEL (Titanium Enhanced Silica Gel) desiccant wheel and drive. The dehumidifier will be provided with an electric reactivation heater assembly with automatic energy modulation control.

• SWSI forward curved type, direct driven reactivation fan with a 1-HP TEFC motor and manual balancing damper.

• The reactivation inlet airstream will be filtered with a metal mesh prefilter assembly.

• The desiccant wheel assembly will be supported on industrial rollers with an integral sealed bearing assembly.

• Perimeter and radial silicon industrial rated compression bulb seals will be provided on the entering and leaving side of the wheel to ensure performance integrity and prevent any cross leakage. The seal surface will have a laminated Rulon surface to minimize frictional contact and extend the life of the seals.

• Plenum construction will be 0.125-inch welded strain hardened aluminum with 1 inch of Armaflex insulation.

• The dehumidification system sections will be mounted on a temporary shipping base.

• The dehumidification system will be designed for indoor mounting and a 460/3/60 electrical power supply.

Standard Controls Package:

• NEMA 4 control enclosure with motor starters, control relays, power distribution blocks, transformers and control power terminal blocks.

• The system control logic (sequence of operation) will be accomplished with a Siemens S7-1200 series PLC and will be provided with the necessary discrete and analog 1/0 for functional operation of the desiccant wheel, reactivation, and process fan. Contacts will be provided for PLC interface, alarm notification and fault notification.

• A Siemens model KTP400 color touchscreen HMI will be provided for user interface with the PLC and visual display of the system status and operating parameters.

• The PLC will be provided with Modbus RTU Slave communications capability (integration to the customer building management system by others).

• The process fan enable signal will be set up with a 'constant process fan' design where the fan is always on when the system is enabled.

• System inlet and outlet connection types will be as follows - process inlet and outlet bolt pattern, reactivation inlet bolt pattern, and reactivation outlet bolt pattern.

• Process air MERV8 prefilter assembly. The filters will be mounted in a side-loaded configuration.

• Process fan will be a model 700-35, SWSI forward curved type, direct driven with a 2-HP TEFC motor and manual balancing damper. Fan assembly will be end-mounted (no plenum).

• (3) 7-3/4 24VDCto 115V relay to interface with Protec Controls start stop relay.

Munters' standard parts warranty.

4 EACH Munters HC-150 Dehumidifiers or equal

• Designed for a 115/1/60 power connection (30564-01)

• Durable housing with a welded aluminum construction

• Honeycomb rotating SIGEL (Titanium Enhanced Silica Gel) desiccant wheel and drive assembly.

• ETL Listed, conforms to UL Std 1995, certified to CAN/CSA Std C22.2 No. 236

• Hinged access panel for inspection and maintenance without disconnection of ducting or wiring

• Electric reactivation heater assembly with energy modulation

• Solid state control system and control indicating package with fan and overheat fault circuits

• Process and reactivation fan and motor assemblies

• Metal mesh inlet filters

• Process inlet insulation to retard external condensation, 1/2" thick

• Blast gate dampers shipped loose: 5" diameter for the process airstream and 4" diameter for the reactivation airstream

Please ship materials as soon as they are available. Do not hold to ship all together.
