Portsmouth Naval Shipyard will be issuing this solicitation for a basic contract, under which orders will be placed to rent equipment over a twelve month period. The unit is to be an air-cooled High Pressure Air Compressor with appropriate air purification system to be able to deliver 15-20 CFH air at 5000 psig. The compressed air to be dried to a dewpoint of (-) 60 degrees F at atmospheric pressure. (+ 20 degrees @ 4500 psig), and contain not more than 1 ppm/w Oil Vapor in the finaldischarge air. The air compressor shall have not less than 5 compression stages with appropriate intercoolers and after cooler so as to provide discharge air temperatures of 100 degrees F or lower. The compressor/dryer assembly shall be complete operating unit as described in this section when delivered. The unit shall be electric motor driven at 460VAC, 60 Hertz, with a maximum motor speed of 1800 rpm. The motor to be suited for outdoor operation in 0 degrees F temperatures without the need for additional shelter. The motor is to be air cooled, totally enclosed and size shall be up to 100 HP. The air compressor shall be able to continuously compress free air to 5000 psig, and have a discharge capac9ty of 15 to 20 CFH @ 5000 psig. The unit shall be enclosed in a weatherproof enclosure. The air receiver shall be at least 1.5 cubic feet and shall be attached to the unit to eliminate short cycling of the compressor. The receiver shall have a pressure relief valve and manual drain valve installed. Compressor andMotor Controls and Safety Equipment shall be installed as part of the unit. These shall include, but are not limited to: high pressure stop switch, high temperature cutout switch, stage safety valves, low oil pressure cutout switch, overload circuit breakers or fuses. The compressor shall meet ASME power piping requirements and electrical components are to meet NEC requirements for service intended. Safety controls shall include a full voltage magnetic motor starter, indicators and safety shutdowns for compressor and air system protection. Individual State Condensate Drains both automatic and manual drain valves shall be installed, with a condensate collection system consisting of a 15 gallon or larger sump equipped with a manual drain valve. Automatic condensate drains may be either timed or level sensing. Manually operated drain valves are to be installed as a backup in case the automatic drain fails. Air Purification Equipment consisting of a moisture separator capable of being blown down manually; one ormore oil/particulate filters (Coalescing oil/particulate filter(s) shall be capable of removing particulate matter as small as 15 microns. The filters shall contain replaceable cartridges and be comparable to CUNO Micro Clean Filter Cartridge No. 2278-B2 or U78-B2 or equal. An air drying method shall be installed to bring the final air quality to a dewpoint of minus 60 degrees F when measured at atmospheric pressure. Regenerative tower type dryers ARE NOT acceptable due to the excessive amount of controls and maintenance required on those devices. Air dryer assemblies shall be equipped with a back pressure-regulating valve (Priority Valve) at the discharge end of the dryer unit to prevent a large pressure drop across the air dryer assembly. All spare parts shall be furnished by the Contractor. The contractor shall be responsible for on site start up and all routine maintenance, i.e. change oil, filters, lubricant, coolant, etc. except for daily check of liquid levels. Equipment shall be delivered in first class operating condition with complete operating instructions. The equipment shall be wired electrically to enable a single point Shi0pyard connection. On the fin al high-pressure air discharge connection, the contractor shall have installed a inch IPS union tailpiece for connection to shipyard systems. The connecting tailpiece shall have 1 " 12 male threads on the union tailpiece so as to be adaptable to a shipyard furnished nut and tailpiece with the O-ring on it. The Contractor shall be responsible for equipment failure not arising out of abuse or negligence by the Government.
