This document is a technical specification file for Air Handling Unit 16 (AHU16), detailing existing equipment and components required for a facility's HVAC system.

The AHU16 system comprises several key components: a Wall Fan (WF-12) rated at 2,130 CFM with 2,890 static pressure and 635 RPM, and an Exhaust Fan (EF-20) rated at 23,632 CFM with 2.25 static pressure and 879 RPM. The prefilter section contains a 1-combination filter (22 inches) with 30,000 CFM air volume, featuring a Throwaway MERV 7 prefilter and Varicel SH cartridge filter. The steam coil section includes 2 coils (12 inches) with model 8JA0801C, capacity of 2,900,906-3,299,896 Btu/h, 30 PSI steam pressure, and a condensate load of 3,229-3.5,512 lb/hr. Materials include aluminum (C-6066) and copper (C25) fins with copper tubes and galvanized steel casing. The humidifier section features a future coil setup with 2 coils and 2 rows, stainless steel drain pan on the drive side. Cabinet dimensions measure 132 inches wide by 88 inches high, with multiple connection points for steam inlets/outlets, cold water inlets/outlets, and condensate drains positioned at specified coordinates throughout the unit.

Supporting documentation includes piping details for freeze-proof steam preheat coil connections with dual steam traps and capacity control valves at 1/3 and 2/3 capacity, plus humidifier piping connections using short absorption tubes with manual shut-off valves and modulating control mechanisms. A 1,000 PPH clean steam generator (model CS-001111 MVVAB) produced by Advanced Steam Technology provides steam supply, featuring stainless steel construction, 150 PSI ASME stamp rating, and integrated level controllers with high and low alarms.
