About this file
This is a Statement of Work for the procurement of a Generon 6800 CP Series cabinet-enclosed membrane nitrogen generator. The Naval Air Warfare Center Propulsion Systems Evaluation Facility at Patuxent River, Maryland requires one unit to convert dry, unfiltered compressed air into nitrogen gas for a test rig, with installation within a 3 ft. by 6 ft. footprint. The generator must deliver 240 SCFM of nitrogen at 96% purity when supplied with 115 psig compressed air at 75°F, with a minimum discharge pressure of 90 psig and capability to maintain 100 SCFM at 99% purity. The unit must operate with unfiltered compressed air at pressures between 100 and 150 psig with a pressure dewpoint of 38°F or below, feature a minimum 10-year membrane life at 100% duty cycle, include automatic purity control adjustment from 96% to 99%, and accommodate variable downstream pressures between 0 and 150 psig with continuous, intermittent, or fluctuating flow demands.
The cabinet enclosure must not exceed 3'-0" wide by 6'-0" long by 10' high and include internal pre-filtration equipment, an automated inlet shutdown valve, output purity indication, purity assurance system with off-spec diversion capability, NEMA 4 control panel with local HMI, stainless steel piping, forklift slots for handling, and comprehensive documentation including P&IDs and maintenance manuals. The equipment must be accessible for maintenance when positioned within 6" of walls or storage tanks, comply with NEC standards, operate on 60 Hz AC power, and meet stainless steel piping requirements. Delivery is required 12 weeks after contract award to Naval Air Warfare Center Aircraft Division, Patuxent River, Maryland 20670, with FOB Destination shipping included. The warranty covers 12 months from startup or 18 months from delivery, whichever occurs first, and the compressed air flow shall not exceed 550 SCFM for the specified 240 SCFM nitrogen output at 96% purity.

STATEMENT OF WORK
(10 February 2026)
Membrane Nitrogen Gas Generator
BACKGROUND
The Propulsion Systems Evaluation Facility (PSEF), Patuxent River, MD has a requirement for a membrane nitrogen generator to convert dry, unfiltered, compressed air to nitrogen gas to supply a test rig. The membrane nitrogen generator will be installed indoors within a 3 ft. x 6 ft. footprint.
TECHNICAL REQUIREMENTS
CLIN 0001: GENERON 6800 CP SERIES CABINET ENLCOSED MEMBRANE NITROGEN GENERATOR
MEETING SPECIFICATIONS BELOW: Quantity - 1
a) Membrane type nitrogen gas generator with minimum membrane life of 10 years at 100% duty cycle.
b) Nitrogen discharge gas flowrate of 240 SCFM (Standard Cubic Feet per Minute, referenced to 68°F at 14.5 psi) at 96% (by volume) purity level with dry, unfiltered compressed air supply of 115 psig at nominal 75°F.
c) Minimum nitrogen discharge pressure of 90 psig for a 115 psig air supply pressure.
d) Fully automated control of purity levels from 96% to 99% based on user adjustable setpoint input.
e) Minimum flowrate of 100 SCFM at 99 % purity level for inlet pressure of 115 psig.
f) Flowrate adjusts automatically to meet demand.
g) Nitrogen gas discharge flow compatible with continuous, intermittent, or fluctuating flow demand and variable downstream pressure between 0 and 150 psig.
h) Operates with unfiltered compressed air at compressed air supply pressures between 100 psig and 150 psig at pressure dewpoint of 38°F or below.
i) Nitrogen Generator is housed in a cabinet enclosure with maximum overall dimensions of 3’-0" Wide x 6’-0" Length x 10’ Height
j) Includes pre-filtration equipment internal to cabinet enclosure to handle moisture and particulates
k) Includes an automated membrane inlet shutdown valve to protect membrane from moisture and particulate contamination.
l) Includes Output purity level indication
m) Cabinet includes forklift slots suitable for unloading from delivery truck, transport, and positioning during installation.
n) Includes purity assurance system with automatic valve to divert Off spec (below setpoint purity level) nitrogen to Off spec port for customer routing to atmospheric vent
o) NEMA 4 control panel with local HMI (Human Machine Interface) for operator interface
p) Shipping to 20670 included, FOB Destination
q) Includes port for customer to route the oxygen enriched waste gas to atmospheric vent at ambient pressure.
r) Includes documentation: P&ID (Process and Instrumentation Diagram), operating manual, and maintenance manual.
s) Access for controls and routine maintenance are compatible with cabinet installed with 3 ft. side positioned within 6” from a wall, and a 6 ft. side positioned within 6” of a nitrogen storage tank, leaving only two sides available for controls and access for routine maintenance.
t) Compressed air flow shall not exceed 550 SCFM for 240 SCFM, 96% purity, nitrogen gas output.
u) Meets NEC (National Electric Code) Standards
v) 60 Hz AC power compatible
w) Stainless steel piping
x) Warranty for 12 months from startup or 18 months from delivery, whichever comes first.
DELIVERY SCHEDULE
Delivery 12 weeks after contract award.
