03
New Inspiration
Units are compatible to various Air Volume incorporating VFD’s, Control Panel,
Heat Recovery Wheel Multi stage Filtration, UV Lamp and Heating Provisions.
Floor Mounted Horizontal / Vertical Double Skin Air Handling Units, FCU, ECU
and Wet Scrubbers.
Rigid Framework of Extruded Aluminium Alloy Anodized which is Anticorrosive
and filled with Polyeurethene foam. The structures have chamfered ends which
avoids any sharp corners. The three way Corner Joints used are of Fiberglass
reinforced Nylon or Die cast Aluminium. For Outdoor application the sections
and the Corner Joints are available with thermal break. The special extruded
sections with L shaped grooved in suitably with gaskets are for air tight joints.
The three way joints allows easy dismantling of the panels for easy
transportation and assembling at site.
Underdeck housing skid
The frame work provided is of heavy duty Galvanised steel structure
interconnected with Die Cast Aluminium corners to form suitable rectangular
frame work. The Air Handling Unit structure is mounted on top of this skid. This
will ensure easy drainage of condensate water from the tray located beneath
Cooling Coil. Galvanised Steel Structure reinforcement is provided beneath the
location of Fan and Motor assembly for rigidity.
Double Skin Panels
The Panels have outer skin of high quality Pre Painted GI Sheet to avoid
scratches and marks. The inner skin is of Plain Galvanised Steel / Aluminium /
Stainless / Pre Painted / Pre Coated Sheet. Polyeurethene foam closed- cell of
density 45 Kg /m3 is achieved by pressure injection of the Chemicals in exact
ratio or Rockwool / Glass Wool to ensure excellent thermal & sound insulation
and potential condensation. The thickness can be of 25/45/50 mm. The panels
are secured to the frame work with FG closed cell rubber gasket.
Return Air Chamber can be provided with dampers as an optional item for
connecting Return air and Fresh air.
04
Filters
The filter section is designed for easy removal of filters. Filter Frames are made out
of heavy guage Galvanised sheet. Pre filters are made of non woven filter fabric in
multiple pleated form to provide more filtration area fitted within extruded
Aluminium frame with bonding agent. The filters are capable of filtering dust
particles up to 10µ having 90% to 99.99% efficiency, 5µm, 3µm, 1µm and 0.3µm.
initial efficiency of these filters with atmospheric dust is greater than 98%. By pass
damper along with quadrant & manual locking can be provided as optional feature.
Cooling coil
The cooling coil is manufactured to achieve maximum cooling performance by using
Aluminium fins with Zigma corrugation and mild ripples / Hydrophilic Blue Fins
designed for minimum air pressure drop. Cooling coils have 12 fins per inch. The
copper tubes brazed with hair pin bends to reduce the usage of U bends. The end
support plates of the cooling coils are made with Galvanised sheets / Stainless Steel
Sheet of adequate thickness based on site requirement. Copper tubes (Plain / IGT)
are expanded to obtain proper bonding with the fins by hydro pneumatically / bullet
expansion. The cooling coil headers are made from MS / Cu pipe. Cooling coils are
normally with 4 Rows for comfort application. Based on design conditions cooling
coils can be provided 6 / 8 Row as optional. Pre Heat / Reheat Coils with Hot Water/
Steam can be provided as optional item. The maximum horizontal length of the
finned coil is determined by the working width of the interior of the air handling unit
and expressed in mm. The depth of the heating/cooling unit is composed of a
specific number of rows of tubes facing the direction of air flow. The number of
rows is calculated according to the air flow conditions at the inlet and outlet of the
unit, based on the cooling or heating energy used by the equipment.
Condensate Drain Pan
Condensate Pan is fabricated with Stainless steel Sheet with gradient towards the
drain outlet to avoid water stagnation in the tray. The insulation is carried out with
high efficient closed cell elastomeric foam / Polyurathene Foam. Suitable Heavy
Steel / Stainless Steel bridges are provided to support the cooling coil. The drain
pan is easily accessible for periodic cleaning.
Drift Arrestor
When the velocity across the coil is 2.5m/s more or when the water content of the
air is greater than 10.5 g/kg of dry air, a specially designed GI / PVC Drift Arrestor is
placed to arrest carryover of mist particles and allow clean and cool air to pass
through.
05
Fans
This section is composed of a centrifugal fan with an anchor bedplate, drive and electric
motor or plug-fan. The centrifugal fan motor assembly is mounted on Silent bloc
bushings and the discharge outlet is joined to the opening in the enclosure by means of a
flexible fire retardant synthetic seal. This allows the unit to run without external
transmission of the small vibrations normally caused by fan motor assemblies.
Centrifugal fan
There are three types of fans that cover all needs: the forward and aerofoil models for
low pressures and the backward for medium and high pressures.
Plug fan
Plug fan built into an acoustically insulated air handling unit. A plug fan supplies air at the
fan section outlet with a low and even air speed in certain situations. Therefore, be an
advantage to position air handling components on the outlet side of the fan. Single inlet
plug fan with open outlet into the air handling unit. The fan impeller is fitted directly to the
motor shaft. This fan type has low sound power levels in the lower frequencies. Efficiency
up to 75%. The motor is supplied with a Single speed motor.
EC Fan
The EC fan is equipped with a Single Inlet Centrifugal Impeller with High Efficiency
Backward curved blades and external rotor EC (Electronically Commutated) motor,
energy optimized for operation without spiral housing for high efficiency and favourable
acoustic behaviour. The high efficiency backward curved impeller with rotating diffuser,
made of high performance composite material / welded aluminium sheet material, with
external rotor motor balanced together statically and dynamically. The EC fan is capable
of being fitted in horizontal or vertical position in the AHU, depending on the application.
Direct Driven Fans
DIDW Direct driven centrifugal fans with forward curved impellers suitable for AHU, FCU
and other OEM product requirement. It comes with a single-phase, 4-pole and 3-speed
capacitor motor capable of delivering good airflow and pressure at the 3 different
operating speeds.
Single Inlet Single Width Fan
SISW centrifugal fans with high efficiency non-overloading backward curved impellers.
The fans are suitable for supply or exhaust applications in commercial, process and
industrial HVAC systems
06
Belt Drive Assembly
Standard cross section "V-belt" drive with 1.2 service factor. Adjustable
pitch motor pulley and fixed pitch blower pulley
Heat Recovery / Energy Recovery
Heat Recovery Rotating regenerative air-to-air recovery unit Specially designed to
transfer sensitive (temperature) and latent (humidity) heat from the exhaust air to
the supply air. The supply air stops in one of the halves of the heat recovery unit,
while the exhaust air circulates in counter flow through the other half. When the
impeller turns, the small air flowing channels comprising the impeller are alternately
in contact with clean air and with return air, transmitting heat and moisture from
one circuit to the other.
Dampers
AHUs are equipped with Heavy Duty, multi blade and low leakage dampers to
modulate and control the air flow. Dampers are prepared for either manual or
motorized operation.
Ultraviolet Lamps for Cooling Coils
The system is designed for installation into air handling units for the purpose of
surface disinfection using ultraviolet germicidal irradiation.
Designing of Static Pressure
Adding the various pressure drops for the unit for an air velocity of 2.4 m/s:
• Air mixing section (M) 30 pa
• Extended surface filter section (F) 72 pa
• Heating unit 2 R 35 pa
• Cooling unit 4 R 85 pa
• Cooling unit 6 R 120 pa
