Repair Chemical Feeders for Heating and Chilled Water Systems

Contractor needs to provide all labor, materials and work necessary for retrofitting heating and chilled water chemical feeders with bypass filter feeders in multiple buildings, in accordance with this Performance Work Statement (PWS) at Peterson AFB, CO. As our HVAC systems age, solids (dirt, metals, etc.) in the systems build up over time and filtering out solids will protect equipment in system. The replacement cartridges can be added to our supply stock and chemical feeder will be included in our HVAC maintenance schedule. Tasks: - Isolate flow on existing chemical feeder. Demo and dispose of existing chemical pot feeders at each location. Typical connection is downstream from the expansion tank in system. - Provide and install feeder filtration unit at each location. Unit shall be Neptune VTFC-2 model or approved equal. Unit features include ¾” inlet and outlet, filter built in support for cartridge filter, maximum pressure 200 psi, maximum temperature 200 deg F, fill opening 3-1/2” and 2 gallon capacity. Connect to existing heating/chilled water supply and return lines. - Provide all modification to existing piping to make connections for new system functionality including supply inlet and outlet along with piping to drain. - Filters shall be the same size for standardization across the projects. Provide initial high temperature, 20 micron cartridge filter for each system, and a case of 10 for bench stock. - Reinsulate reworked piping. This work will be performed for the following buildings on Peterson AFB: Bldg 1 Heating Water System (Escort Required) Bldg 1 Chilled Water System (Escort Required) Bldg 590 Heating Water System Bldg 1030 Heating Water System Bldg 1030 Chilled Water System Bldg 1013 Heating Water System Bldg 1470 Heating Water System (Escort Required) Bldg 1470 Chilled Water System (Escort Required) Bldg 2025 Heating Water System Bldg 2025 Chilled Water System Bldg 218 Heating Water System
