SPECIFICATION FOR

PORTABLE NITROGEN PRODUCTION UNIT FOR FIRE SUPPRESSION

1. SCOPE:

1.1. This specification reflects those characteristics that are essential to the minimum needs of the Government for a “Turnkey” Portable Nitrogen Production Unit for Fire Suppression (NPU). This specification provides the performance standards for purchase of an electrically driven; Nitrogen Membrane Generating System. This system should be designed to supply a continuous flow of nitrogen of a minimum of 300CFM with a minimum working pressure of 85PSIG to 100PSIG, at a minimum nitrogen purity of 95% (Nitrogen Purity + Inerts). Feed air at a maximum of 625 CFM.

1.2. This contract includes setup, testing, startup assistance, training, and on-site technical support. It is the Government’s intent that a single (primary) contractor experienced in the production of membrane generating system technology in the marine industrial environment be awarded this contract and be responsible for the accomplishment of all work, including 3rd party certifications.

2. CONTAINER:

2.1. The NPU shall be a stand-alone, “Turnkey” system. All components for the NPU should be installed within a max 8’ wide x 8’ high x 10’ long insulated, able to withstand when ambient temperatures drop to 28°F. ISO container, designed to permit relocation by crane, truck, and forklift.

2.2. The components utilized for the design of this system are commercially available off the shelf (COTS) and should require only integration, assembly, operational verification and certification in final configuration to meet the contract specifications.

2.3. The proposed layout of equipment will be based on average component sizing across industry. Innovative designs that improve system function, capacity, size, weight, or cost are encouraged to be included by the offeror in response.

2.4. The NPU shall be designed for operation at sea-level altitude, in the weather exposed to sun, freezing rain, snow, sleet, high and low temperatures, high and low humidity, and other climactic extremes. The operating environment is marine waterfront; therefore, components and coatings must be selected for protection from this corrosive environment.

2.5. The NPU capacity at the outlet of the shipping container shall be capable of delivering minimum of 300CFM with a minimum of 95% purity while meeting all requirements for production, handling, and delivery of industrial grade Nitrogen. Operational performance design of the NPU should target the General Industrial usage.

3. SAMPLING REQUIREMENTS:

3.1. The NPU shall be NRTL certified. The offeror will obtain and provide independent 3rd party Nationally Recognized Testing Laboratory (NRTL) certification listing for the NPU and ensure NPU assembly is properly marked with NRTL certification marking.

4. SET UP SERVICES AND TESTING:

4.1. A certified technician for the nitrogen generator and all associated equipment shall be assembled, set-up and tested by the contractor in the area(s) designated as the test area by the receiving activity. The Contractor shall provide all personnel, equipment, and supplies necessary for the complete set-up and testing of the nitrogen generator.

4.2. Two (2) paper copy of shutdown, startup, operating, and maintenance procedures in English.

5. TRAINING:

5.1. Training can be performed on-site at the receiving facility upon arrival of the unit. Training will consist of operation of the unit to include proper maintenance of the system. Customer will be charged at the current daily service rate, plus travel and living expenses.

6. NOISE:

6.1. Obtain, provide, and install an active industrial noise suppression system inside of the NPU to ensure ambient noise levels outside <84db not to exceed <103db and inside of the containerized unit <104db not to exceed <120db.

7. SOFTWARE:

7.1. HMI: Displays oxygen content, feed pressure, Nitrogen pressure, run status, maintenance hours, standard factory set process control valve, Zirconium oxide oxygen analyzer.

8. REQUIREMENTS:

8.1. The NPU shall be a complete and operational system, delivered assembled, piped, wired, and tested. After delivery, the unit shall require only the connection of power, routing of condensate, and testing in accordance with this specification.

8.2. Provide calibration gas (GASCO 103L-159-10 or similar), calibration rig, and procedures to verify both in-situ (installed) O2 sensors can accurately measure a minimum purity of 95% that is calibrated to certified standards that have known valid relationships to nationally accepted industry standards.

8.3. Supply a continuous flow of nitrogen from minimum of 300CFM with a minimum working pressure of 85PSIG to 100PSIG, at a minimum nitrogen purity of 95% (Nitrogen Purity + Inerts).

8.4. If membrane required specific temperature range to meet operational conditions a process heater shall be installed on the inlet piping.

8.5. After the feed air heating step, the Feed Air is passed through another conditioning step. The feed air is passed through an Activated Carbon filter. The activated carbon is utilized to remove from the feed air any Hydrocarbons that may be present in the air stream as a result of the compression process. The filter has a built in .01 dust particulate wrap to ensure no carbon particulates enter the membranes.

8.6. All electrical components to meet an area classification of Safe No Hazard.

8.7. Power supply: 120 Volt, 1 Phase, 60 Hertz authorized to be supplied through a transformer on the 480 Volt supply, 480 Volt 3 Phase, 60 Hertz
