ANNEXURE-III
TECHNICAL SPECIFICATIONS
1. AIR HANDLING UNITS
The scope of work shall comprise of supply, installation, testing & commissioning of double
skin construction air handling units of the capacity & type indicated on drawings as well as
Bill of Quantity. The air handling units shall comprise of casing housing filter, coil & fan
section. Additional sections, if required, like mixing box, second row of coil, additional filter,
dampers etc would be indicated in drawings and bill of quantities. Computerized fan
selection print outs shall be submitted along with the technical data sheets. Air handling
unit shall be selected for the lowest operating noise level and fan performance rating,
power consumption data along with operating points clearly indicated shall be submitted
prior to supply for Client/Consultant approval. These will be verified at the time of testing
and commissioning of the installation.
1.1 Casing
The casing shall be formed out of two layers of minimum 24 gauge GI sheets with 25 mm
or 50 mm thick pressure injected PU foam insulation of 40 kg/m 3 density (K factor not
exceeding 0.02 Watt/sqm) in cavity space. The structural framework shall be constructed
out of 1.5 mm thick aluminum box section with self-drill screws. Outer sheet shall be
provided with 0.63 mm thick PVC guard film. Neoprene gasket shall be provided for sealing
the frame with panels which will be concealed after fixing. No gaps shall be visible between
the panel and frame work. Outward opening access doors of double skin construction shall
be provided for both coil and fan sections. Actual number of access doors shall be as called
for in the approved shop drawing. Door hinges shall be manufactured from hard nylon or
die cast aluminum. For doors provided downstream of the fan, especially in high static
AHUs, additional clamps shall be provided along periphery of door to maintain constant
pressure and ensure proper sealing. A micro switch interlocked with door including power
wiring shall be provided such that fan motor stop running upon opening the door. Base frame
shall be constructed out of aluminum or galvanized steel as per manufacturer’s
recommendation. Each partition shall be of sufficient thickness and provided with stiffening
arrangement to prevent deflection and vibration during AHU operation. All internal surfaces
including internal fittings such as dampers shall be with beveled edges and without sharp
corners to prevent operator injury. There shall be no screws projecting into AHU or air
stream. Water resistant marine light with power cabling shall be provided inside the AHU for
service & maintenance.
AHU’s with mixing boxes shall be specified in Bill of Quantities and include outdoor air and
return air dampers.
Insulated condensate drain pan using 19 mm thick cross linked polyethylene/nitrile rubber
and fabricated from 18 guage stainless steel sheet shall be provided. It shall be isolated
from bottom floor panel for ceiling suspended units externally insulated for floor mounted
units.
In case a opening is made at site in AHU panel, then a GI C-channel cut at 45 degrees shall
be provided all around to prevent entry of PUF into air stream. Double lip & tight fitting rubber
grommets shall be provided at all openings in AHU casing such as coil connection, cable
entry etc.
All outdoor application, TFA units and those with ducted return air shall be provided with
thermal break and casing with 50 mm thick insulation. The supplier shall provide a written
guarantee that no sweating on pane surface shall be observed in ambient conditions of 35
0C and 92% RH. Any additional precaution to demonstrate satisfactory compliance to above
requirement shall be included in AHU design.
The nameplate mounted outside on the AHU casing shall provide relevant details including
AHU model, fan model, motor KW, current drawn, air quantity and total static pressure.
