Equipment Performance:
Air Enterprises had just completed another phase for this repeat user of Air Enterprises equipment in their West coast US facility. The decision to award the air handling units to Air Enterprises for an expansion in the Puerto Rico facility was made with confidence. Air Enterprises' all aluminum housing which interlocks with connecting aluminum extrusions was critical to address the high static pressures involved.

Units were guaranteed to maintain 1/2% leakage at design static pressures. Housing integrity, deflection and leakage were also critical to maintain the seal at the 99.97% efficient HEPA filters. All HEPA banks were field DOP challenged and scanned for sub micron particle integrity.

Unit components consisted of Class II and Class III DWDI fans with inlet vanes & stainless steel inlet screens, TEFC high efficiency motors with auto tensioning belt drive bases, dampers, 30%/95%/HEPA filtration, chilled water coils with stainless steel, sloped drain pans, and reheat coils. Factory-provided electrical features included a fluorescent lighting system and fan motor disconnects wired within all-aluminum conduit.

Complete factory testing services consisted of casing leakage, electrical integrity, unit air flow, and a sound analysis. Complete field supervision, start-up and owner orientation services were included.
