COIL OPTIONS
25mm double skinned panels provide better
acoustic and thermal properties over conventional
AHU’s.
Fan impellers are selected for optimum efficiency
and noise characteristics. Motors are IE2 to BS 5000
direct drive and high efficiency belt drive.
DX & chilled water coils are available, call Nuaire
for further details.
Note: Undressed coils are also available.
REDUCE INSTALLATION TIME
IMPROVED LIFE CYCLE/NO SYSTEM
OVERLOADS
WARRANTY
All components are pre-assembled, wired and
tested at the Nuaire manufacturing facility. Units
are delivered conveniently in sections for easy site
assembly.
Ecosmart Boxer has a 5 year warranty.
Ecosmart is pre-programmed to automatically give
a soft start function which prevents electrical
overloading and minimises mechanical wear.
SIMPLE PRECISE COMMISSIONING
LONG LASTING
Minimum and maximum ventilation rates precisely
set and limited at AHU requiring no throttling
dampers.
Each section is manufactured from a highly rigid
pentapost framework with heavy gauge AluzincY,
corrosion resistant steel panels.
ENERGY EFFICIENT
CONSTANT PRESSURE CONTROL
AVAILABLE
All models have Ecosmart controls built in, which
provide the most energy efficient and cost effective
solution.
For further information contact Nuaire.
ANCILLARIES & COMPONENT OPTIONS:
Weather terminals.
Silencers.
Dampers.
Vertical and horizontal heat exchangers.
Base frames.
DX Coils.
Monometrer.
Filter sizes 1 & 2 = G4 panel,
sizes 3 - 7 = G4 bag or G4 bag & F7 bag.

ECOSMART BOXER UNITS SIZE 3 TO 7
AIR HANDLING UNIT SPECIFICATION
The Air Handling Unit shall be configured and arranged as detailed on the
drawings and in accordance with the schedule of equipment. The units shall be
manufactured from a highly rigid pentapost framework with 25mm double
skinned infill panels. The panels shall contain inert high density infill.
Panel materials are heavy gauge Aluzinc corrosion resistant steel. The units shall
provide exceptional thermal and acoustic insertion. The general construction is
to class A leakage.
The fan impeller and motor shall be selected to provide the most energy
efficient solution conforming to part L regulations and shall be direct or belt
drive with IE2 high efficiency motors to BS5000 as standard. The fan impeller
shall be a high efficiency forward or backward curved centrifugal design,
manufactured in galvanised steel.
The Fan unit shall have a 5 year warranty.
The unit and ancillaries shall be of the Ecosmart Boxer type as manufactured by
Nuaire Ltd.
All other components shall be in accordance with the manufacturer’s
specification.
CONTROL SPECIFICATION
The Air Handling Unit shall be supplied with one of the following control
options:-
1. ECOSMART CONTROLS The compact Ecosmart control system complete with all necessary controls to
facilitate the operation of the ventilation system. It shall be come complete with
an integral factory fitted Ecosmart PCB which will control the fan unit within the
desired design parameters and provide the interface between all external control
devices and the unit itself.
ECOSMART SYSTEM OPERATION
The Ecosmart controls will enable the unit to automatically vary its speed as it
receives signals from one of the interconnected sensors. When the signal is
received the fan shall either increase speed gradually until the required level is
achieved or it will work on a trickle and boost principle. This will then and move
the fan duty point from trickle/background ventilation rate to the required boost
ventilation rate. Both the trickle and boost rates are infinitely variable, easy to
adjust and remove the need of a main balancing damper.
2. BMS INTERFACES
The fan unit shall be provided with the following integrated BMS interfaces
• 0 - 10 volt contacts to provide a full BMS interface. This will enable the
following functions:Switch the unit on/off.
Switch from low speed to high speed.
Full speed control facility.
Switch the heating function on/off.
Switch the cooling function on/off.
• 2 No. Volt free contacts to provide fan run and failure indication to provide
system status.
• An integrated commissioning/speed control to accurately commission the
system, with minimum and maximum speeds easily adjusted via a miniature
dial, as recommended in Part L. This will enable the unit to be configured to
run between set parameters thus saving motor power and limiting noise.
• Commissioning set up - The fan unit shall be provided with an integrated
commissioning/speed control to accurately commission the system, as
recommended in Part L, minimum and maximum speeds easily adjusted
via miniature dial. The commissioning set up facility directly controls the
integrated speed control/frequency inverter.
3. NO CONTROL IS AVAILABLE
(Example code BHS7NC-E).
The Air Handling Unit shall have the following energy saving components
integrally mounted, pre-wired to interface with the purpose made PCB, all
components pre-wired, configured and factory fitted by the manufacturer: • Integral Frequency inverter/speed controller.
• Integral maximum and minimum speed adjustment for commissioning.
• Integral adjustable run on timer.
• Integral BMS interfaces – summer/winter switching, heating control,
0-10V speed adjustment.
• Volt free failure and status indication.
• Integral air off temperature adjustment.
• Facility for remote temperature control.
• Integral background ventilation switch (trickle switch).
• Multiple IDC sockets for interconnection of sensors or fans using pre-plugged
4-core low voltage cable.
• Volt free frost alarm/heat demand interface.
• Frost protection/hold off stat.
114
029 2085 8200
COIL TYPES, HX AND CONTROLS
The control for the coils shall be fully integrated and shall maintain a constant
off coil temperature. The system shall have frost protection which shall, at
temperatures below 4 degrees C, fully open the 3-port valve and only start
the fan when the temperature at the filter has risen above the designated set
point. Unit to have contacts which will act as frost alarm and/or signal boiler
to switch on.
