The vendor shall provide, install, and configure a complete rental breathing air package designed for continuous, uninterrupted operation. The system shall consist of two (2) air compressors in an automated lead-lag configuration, two (2) air dryers in a primary/standby manual switchover configuration, and a 1000-gallon receiver tank. The piping and valving must be sufficient to allow any single major component (compressor or dryer) to be completely isolated and removed for maintenance or in case of failure while the redundant unit continues to operate, ensuring no loss of air supply to the facility. 3.2.1.1. Compressor Configuration: The two compressors shall be piped in parallel to a common manifold. An isolation valve must be installed immediately downstream of each compressor, allowing either unit to be individually taken offline without interrupting flow from the other. 3.2.1.2. Dyer Configuration: The two air dryers shall be installed in a primary/standby configuration. • Under normal operating conditions, only the primary dryer will be online, receiving and treating the compressed air. • The secondary dryer shall remain completely isolated from the system via dedicated inlet and outlet valves. It will be depressurized and non-operational (cold spare). 3.2.1.3. Isolation for Maintenance: The piping and valving must allow for the complete isolation of any single component. The system must enable an operator to manually: • Isolate and remove either compressor by closing its dedicated downstream valve. • Isolate the primary dryer and bring the standby dryer online by manipulating their respective inlet/outlet valves. This switchover must be achievable without interrupting the operation of the running compressor. 3.2.1.4. Compressor Automatic Failover(Lead-Lag): The compressors shall be controlled by an automatic lead-lag sequence controller. This controller will designate one unit as “lead” and the other as “Lag.” • Primary Set Point: The Lead compressor will operate to maintain system pressure within the primary operating band. -- 2 of 12 -- STATEMENT OF WORK Low Pressure Air Compressor [LPAC] Spec #: Rev: Page 3 of 12 • Backup Set Point: The Lag compressor will remain in powered standby. It shall automatically activate if the system pressure drops to a lower set point (100 PSI), indicating a failure of the Lead unit. 3.2.1.5. Dryer Manual Failover: The switchover between the primary and standby air dryers is a manual operation performed by an operator. The compressor control system is to be independent of the dryer selection.
