About this file

This document is a York Air Handling Unit (AHU) Performance Report for the VA WPB Cancer Center RTU-3 project. The report provides comprehensive technical specifications for a single outdoor-rated XTO-57x66 model unit with a 7,100 CFM airflow capacity and operating weight of 4,424 lbs at sea level altitude.

The unit features enhanced thermal performance construction with high humidity outdoor air (OA) capability and comprises seven segments in sequence: Mixing Box (MB), Rigid Filter (RF), Cooling Coil (CC), Fan Supply (FS), Access (XA), HEPA Filter (HF), and Discharge Plenum (DP). All major casing segments utilize 2-inch foam insulation with champagne urethane exterior paint (3,500-hour rating), 16-gauge G-90 galvanized steel exterior, and 20-gauge 304 stainless steel interior. The cooling coil operates at 112.5 gpm fluid flow with entering fluid temperature of 44°F and leaving temperature of 56°F, achieving air cooling from 93°F dry bulb to 52.5°F. The supply fan is a Lau DDPG2 direct-drive unit powered by a 15 HP Baldor premium efficiency motor operating at 1,800 RPM, delivering 7,100 CFM at 8.09 inches water gauge total static pressure. The unit includes a pre-filter (MERV 8) and primary filter (MERV 14) in the RF segment, an 11.5-inch HEPA filter (99.97% efficiency) in the HF segment, UV surface decontamination lighting in the CC segment, and a CD50 aluminum airfoil control damper in the MB segment. Electrical requirements include 460/3/60V service at 18.1 FLA for the main disconnect with 40 AMP maximum overcurrent protection, plus 120/1/60V circuits for UV and control components. The unit ships at 4,129 lbs and measures 187 inches length, 78 inches width, and 69 inches height on the shipping skid, with an overall cabinet footprint of 181 inches by 66 inches width and 57 inches height.

Statement of Compliance

Air Handling Unit AHU's meet IBC seismic requirements for non-critical equipment (Ip = 1.0) for locations with design spectral response Sds <= 0.43.

Units must be rigid mounted.

The anchorage of the unit to the ground or building structure needs to be evaluated by and is the responsibility of the engineer of record.

Specification of seismic requirements is the responsibility of the project design engineer. If formal certification is required, please contact your sales representative and/or application engineer for review. Certain application and site requirements may require additional cost and/or lead time.

Component locations are listed as Segment Hand (Unit Hand): ex. Left (Right). See Submittal Drawing for additional details.

Air handling unit parameters vary depending on conditions. Parameters such as airflows, air pressure drops, and coil capacities are shown for design conditions.

Notes Skid Width: Total width of the shipping skid, including any items that may extend beyond the cabinet (this includes any door handles, coil connections, drain connections, lifting lugs, mounted pipe-chases, electrical/control components, tie-down brackets, side dampers).

Skid Height: Total height of the shipping skid, including any items that may extend beyond the cabinet (this includes any base-rails, shipping wood-blocks, roof peak, discharge flanges, mounted gas-furnace flue pipes).

Skid Length: Total length of the shipping skid, including any items that may extend beyond the cabinet (this includes any mounted rain-hoods, discharge flanges, tie-down brackets, shipping wood-blocks, front dampers, split connectors, electrical/control components, outrigging extensions, isolation dampers, inlet baskets).

Shipping Weight: Represents the estimated shipping weight with a tolerance of +/- 10% for values greater than 5,000 lbs. Values less than 5,000 lbs. may have higher percentage variation but not any consequential shipping impact. Shipping weight does not include ship loose and/or field-installed items but does include estimate for shipping materials and/or opening covers.

Operating Weight: Represents the estimated operational weight with a tolerance of +/- 10% for values greater than 5,000 lbs. Values less than 5,000 lbs. may have higher percentage variation. Operational weight estimate includes unit shell, internal components and structure, and known ship loose and/or field-installed items (weather hoods, pipe chases, factory-provided filter media and estimated fluid weight in coils). Actual operating weight will be heaver due to additional field installed materials including but not limited to field-provided filter media, piping, control devices, and/or inertia base concrete.
