Installation of Breathing Air Dryer and Compressed Air Dryer

1. DESCRIPTION OF SERVICES. The contractor shall install a new Desiccant Air Dryer for facility Breathing Air and a Non-cycling Refrigerated Air Dryer for the compressed air in the Building 90225 Compressor Room.

1.1. BASIC SERVICES

1.1.1. The contractor shall remove of and dispose of the following defective existing equipment: Zander Echochill Cycling Refrigerated Air Dryer ZCD-800A and Zander Breathing Air Purification Unit BSP6. These equipment items are located in the building 90225 Compressor room (See attachment 1 for location). The Zander Echochill Cycling Refrigerated Air Dryer ZCD-800A will require deconstruction prior to removal, due to the limited space and pathway into the compressor room from its double doors. See Attachment 2 for (not to scale) general layout of the room.

1.1.2. The contractor shall install Aircel Model BHD-150 Breathing Air Dryer or equivalent, to include NEMA 4 Electrical Enclosure, CO monitoring system, Pre-filter, After-filter, and Final-filter. The system shall produce breathable air in compliance with the special qualifications listed in section 4. The system will need to be retrofitted with the existing airlines in the compressor room, and all electrical components will need to be retrofitted to the those currently existing in the compressor room. Full system start up, and operational training on proper use of the components, as well as, servicing/routine maintenance training shall be provided for shop personnel.

1.1.3. The contractor shall install Ingersoll Rand D1190IN 460/3/60 Nema 1 Refrigerated Non-Cycling Dryer or equivalent. The system may have to be assembled after getting all pieces and components into the compressor room. The limited space and pathways evident in attachment 2 limit the size of the components that can be carried through the room. Site survey of room is recommended prior to install as the attachment is not to scale. The system shall process the compressed air produced from both the compressors located in the Compressor room in compliance with the special qualifications listed in section 4. The system will need to be retrofitted with the existing airlines in the compressor room, and all electrical components will need to be retrofitted to the those currently existing in the compressor room.
