About this file
This is a Notice of Intent to Single Source for HVAC replacement OEM (Original Equipment Manufacturer) parts at Joint Base San Antonio (JBSA) Fort Sam Houston (FSH). The solicitation covers two equipment systems: a BAC cooling tower (Model FXV-641, Serial U107989601) and a Temtrol air handling unit (Model WF-DV15, Serial T000827-007-00). The BAC cooling tower line items (CLIN B3820, line items 0001–0014) include 14 part categories with quantities totaling replacement components such as metal fan shafts (4 each), square steel keys (4 each), flinger collars (4 each), induced draft bearing kits (8 each), bearing shields (4 each), cooling tower motors rated at 25 HP (2 each), aluminum sheaves (2 and 4 each), sheave hardware kits (2 and 4 each), bushings in various styles (2, 4 each), and a BACross fill kit (2 each). All specifications emphasize heavy-duty construction, corrosion resistance, and compatibility with wet cooling tower environments.
The Temtrol air handling unit line items (CLIN B1029, line items 0015–0022) include 8 part categories with 1 quantity each for most items. These parts include a Double Width Double Inlet (DWDI) centrifugal blower wheel at 18 inches (Class II heavy-duty construction), a DWDI inlet cone at 18 inches, pillow-block ball bearings rated at 1-15/16 inches (2 each), precision-ground fan shafts at 1-15/16 inches by 36 inches, motor sheaves, motor sheave bushings, fan/shaft sheaves, and fan/shaft sheave bushings. All parts are specified by exact model numbers, dimensions, material compositions, and performance standards including dynamic balancing to ISO G2.5 standards and straightness tolerances. The single-source justification reflects the specialized, application-specific nature of these OEM components designed exclusively for the identified equipment models and serial numbers.
