SUBJECT: Item Description, P26-005 Desiccant Machine

1. 76 PMXG is requesting the utilization of funds for Desiccant Machine with the following specifications.

2. The requested descriptions/specifications are outlined below.

Vacuum Test Engine

· Connect apparatus to F107 engine and adjust pressure to 27.7 +/- 0.3 inches of H2O.

· Maintain pressure for 5 seconds before recording the flow rate.

· Shall be able to detect flow rate as little ≤ 0 ± 0.010 scfm.

Pressure Test Engine

· Connect apparatus to F107 engine and adjust pressure to 27.7 +/- 0.3 inches of H2O.

· Maintain pressure for 5 seconds before recording the flow rate.

· Shall be able to detect flow rate as little as 0.045 scfm.

Size of Engine Engine Length: 49.35”, Width: 15.56”, Height: 23.61”

System Performance Requirements

· System shall be capable of vacuum and pressure calibration using internal regulators and indicator gauges.

Calibration and Communication

· The contractor shall provide calibration instruction and allow calibration of the system using in house apparatus (PMEL).

· The system shall include ports for data acquisition and communication, enabling monitoring of flow and pressure during test operations.

· Flow and pressure gauges must be accurate to detect flow rate and is clearly readable.

Safety and Electrical

· The entire assembly shall operate on standard 110V AC power and include a grounded plug.

· The system shall include proper grounding mechanisms to prevent static discharge during operation.

· Emergency shutoff functionality shall be included.

Control and Regulation Requirements

· The system shall include clearly labeled and accessible valves/ switches to control including but not limited to

· Vacuum Pump

· Shop Air

· Vacuum Regulator

· Pressure Regulator

· Mode Selector Valve

· Instrument Power

· Control logic must support Mode 1 (vacuum) and Mode 2 (Pressure) operations.

· The operator interface shall be simple and intuitive, providing no more than two selectable options: Vacuum Test or Pressure Test.

· If implemented as a software interface, the selection process shall be limited to two inputs only (e.g. two buttons, two menu options, or toggle), with no unnecessary sub menus or advanced settings.

· The system shall include a fail safe default state that ensures the system powers on in a neutral/ off condition until one of the two modes is selected.

Document and Deliverables

· Contractor shall deliver:

· Operator Manual

· Calibration Procedure

· Wiring and Pneumatic Diagram

· Training Material

· Contractor shall also perform an onside demonstration and functional check with government personnel upon delivery to meet all requirements of the Statement of Work (SOW).

Data Acquisition and Communication

· The current setup has two connections, "SWAGELOK PAT D-QF 4-B-316" on the inlet cover and a "9/16-18 thread" on the engine service island.

· The new apparatus connections shall include AN4- hose connections with stainless braided hosing.

· The connections on the hosing shall be SWAGELOK QC-4 quick connect fittings, featuring KEY 1 (as one hose for pressure) to SWAGELOK SS-QF4-B-4PF connection (the engine side) and Key 2 (second hose for vacuum), with the other end being AN6 to AN4 reducer male to male.

· All hosing shall be a minimum of 5 ft in length.

· To connect apparatus to base airline a 1/4 NPT (male) quick connect is necessary.

3. Contractor shall provide delivery, installation, and performance verification for the Desiccant Machine IAW the Statement of Work (SOW).
