WO 1909045 -- CNIC-64 - NRW 1012, Repair Relief Valve on Chiller #2 LOTO chiller relief valve and water. Repair by replacement (1) leaking relief valve and check for proper refrigerant charge. Return Chiller #2 to operational status and perform operations

This contract, issued by Navfac Washington for the Department of the Navy, involves the repair of a leaking relief valve on Chiller #2 at building 64 in Bethesda. The scope of work requires the mobilization of a refrigerant recovery specialist to recover and weigh existing refrigerant, the installation of one OEM Daikin relief valve using manufacturer-specified torque and sealant, and a comprehensive leak check using dry nitrogen. Following the repair, the contractor must evacuate the chiller to 500 microns or less, perform a vacuum decay test, and recharge the system with the recovered refrigerant. The contractor is responsible for starting and commissioning the chiller to ensure proper operation and providing a detailed report of findings to Invicta personnel to facilitate subsequent Daikin Factory support. While the recovery and recharge of existing refrigerant are included, any additional refrigerant required will be quoted separately or provided by others. The project concludes with the removal of all debris and recovery cylinders from the work site and final demobilization.
