The new refrigerated air dryer shall be sized to sufficiently dry the air at the same air flow rating of the air compressor and operate on 120 volts. The contractor shall install the new tank, compressor, and dryer in RM. G20. The contractor will install all required airline plumbing, valves and regulators, perform factory required start up on the new air compressor, replace the existing refrigerated air dryer and the existing air compressor in Rm G25A and remove the Ingersoll Rand air compressor in G21. The contractor will take possession of the removed air dryer, Quincy duplex compressor system, the Ingersoll Rand reciprocating compressor and properly dispose of the equipment. The contractor will work with VA Engineering employees to set up a temporary air supply while the compressor and dryer are being replaced. Air Dryers: The refrigerated air dryer to be installed with the compressor and new air tank shall be sized to match or exceed the SCFM of the air compressor, the replacement air dryer shall be sized to meet the needs of the control air system in G25A, the dryers shall have environmentally safe freon, the dryers shall operate on 120 volt 20 amp circuit and have a cord and plug for means of disconnect, the dryers shall be wall mountable, the dryers shall have a power switch and monitor status of the equipment and have an integrated alarm to report any dryer operational failures. Air Compressor: Scroll Enclosed Series system complete with multiple (3) oil less rotary scroll compressors, mounted inside of a rigid steel enclosure. The compressor unit shall operate on 480-volt 3 phase power system. Enclosures to have a powder coated finish and include sound deadening insulation. Noise levels shall not exceed 60 dba with all compressor units in operation. Each compressor pump shall have a 1750-rpm TEFC motor, V-belt drive, and air-cooled aftercooler. System to include the Variable Pump Drive Operating System controller for energy efficiency. OILLESS SCROLL COMPRESSOR PUMP Each compressor shall be belt driven oil-less rotary scroll single stage, air-cooled, oil-less construction with absolutely no oil needed for operation. The rotary design shall not require any inlet or exhaust valves and shall be rated for 100% continuous duty. Tip seals shall be of a composite PTFE material and be rated for 8,000 hours operation. Compressor bearings shall be external to the air compression chamber and shall be able to be re-greased in the field for extended life. Patented re-grease ports shall be located on the front side of the pump allowing service without removing the pump drive pulley. Bearings shall have an MTBF life of no less than 33,000 hours. Compressors with bearings that are not accessible for service have a limited life span and shall not be accepted. Pump crankshaft and main bearing housing shall be constructed of heavy duty Cast Iron for maximum durability. Compressors shall have an integral radial flow fan for cooling and shall not require any additional electric cooling fans. Maximum pressure is 145 PSIG. Each compressor pump shall be provided with a dedicated electric drive motor, discharge check valve, flex connector, air-cooled after-cooler, high temperature shut down switch. AIR-COOLED AFTERCOOLER Aftercoolers shall be provided for each compressor unit to reduce discharge temperatures. Aftercoolers are constructed of extruded aluminum and installed at the discharge of each compressor. CONTROL PANEL The controls shall be factory integrated with the compressor cabinet and UL listed.
