Caice Cheetah Fan Coil Units
Fan coil units are the ideal solution for
providing localised air conditioning to ensure
comfortable temperatures in spaces of any
size. The unit consists of a fan which passes
air over a heating and cooling coil to condition
the temperature of the space it serves.
The unit’s coil is supplied by the building’s low pressure
hot water & chilled water systems meaning that it can be
installed anywhere where a water & electrical supply is
available. The simple nature of the product’s operation
makes for easy and cost effective installation in either
new build or refurbished offices, schools, hotels, houses
& apartments.
Thanks to Caice’s expertise in acoustics, our fan coil
units set the standard in low noise operation. The
modular nature of the product means that units can be
customised with built-in attenuation which guarantee that
they will achieve your noise level requirements.
Available in five sizes & powered by the most efficient
fans, our units offer great energy efficiency and effective
air conditioning for any space.

Efficient & Cost Effective
Caice Fan Coil Units are designed and built for
efficiency offering reduced total cost of ownership
and full compliance with building regulations.
Our 300 series range features only Electronically Commutated
(EC) fans. These units are up to 70% more energy efficient at
providing the same duty when compared to their AC equivalent.
With only very negligible amounts of heat being generated whilst
running, this leads to better cooling performance of the fan coil
unit as a whole.
In real terms a typical saving of 60W per fan enables the building
designer to reduce costs by selecting smaller chillers, pumps &
pipework. Longer life expectancy also contributes to a reduction
in the whole life cost of the product.
Compliance
All of the efficiency characteristics of Caice’s fan coil units
naturally lead to full compliance with Document L of the Building
Regulations.
Our entire range of 300 series fan coil units surpass the required
rating of 0.60 W/l/s at all duties, typically operating below 0.40
W/l/s. EC fan motors can deliver typical cost
savings of 60 Watts per fan

Typical Performance
The five units in the Caice fan coil unit range have
been developed to provide effective thermal
performance even at low noise levels.
Based on a typical chilled water system running with a water
flow temperature of 6°C, a return and air off temperature of
12°C with a guide noise level of NR35, the following sensible
cooling duties can be achieved.
Variable Air Volume
When used in conjunction with a Building
Management System (BMS) our fan coil units
fully support Variable Air Volume (VAV) operation
leading to further efficiency gains.
Operating in this mode & triggered by sensors connected to
a BMS, the fan coil unit’s motor speed can be adjusted
using a 0 to 10V DC signal.
Responding to environmental conditions means that under
normal requirements the fan motors can often be run below
full design duty.
This is particularly beneficial when a space is unoccupied,
allowing a substantial reduction in speed leading to
significant energy savings along with reduced noise levels.
Equally fan speed can be increased to provide additional
heating or cooling for higher duty requirements when the
space is occupied.
Fan Coil Unit Size Sensible Cooling Duty
Size 1 1.71 kW
Size 2 3.09 kW
Size 3 3.91 kW
Size 4 5.24 kW

Acoustic Design Service
Where a fan coil unit is being installed in or
serving a noise sensitive area we understand
the importance of making sure that the unit
meets the acoustic design requirement. We
also appreciate that this is a complicated issue
with many contributing factors.
Our unique Acoustic Design Service offers our clients
unparalleled support in this critical area of product
selection and design. We will undertake post-order
acoustic calculations to ensure that all units are selected
to meet the acoustic requirements of a project where
possible. We also carry out a pre-tender design review
where we are specified on an equal or approved basis.
This is why we can say with confidence that our acoustic
design service will guarantee that our fan coil units will
achieve a stated noise criteria, regardless of the
complexity of the installation.
Acoustic Performance
With over 20 years experience in noise control,
our fan coil units offer the kind of unrivalled
acoustic performance you would expect from
any Caice product.
Integrated attenuation options, and acoustically treated
plenums specifically designed to complement our fan coil
unit core module enable us to offer units with reduced
noise levels. This opens up the opportunity to use fan coil
products in applications where more stringent noise level
requirements would otherwise be problematic.
For complete peace of mind our product selections are
backed by certified performance data in accordance with
BS 4856.
As with all of our acoustic air movement products we
offer in-house expertise to support our clients in selecting
the right unit for their needs. This means that whatever
the size of project we ensure that the most cost effective
product which will achieve the room noise design criteria
is selected.

Modular Design
Caice’s modular fan coil unit design allows a solution
to be built up from component options to suit the
needs of a project.
The modular offering consists of the fan coil core, a choice of
inlet & discharge plenums and a range of inlet and discharge
attenuators. Starting with a core unit, modules are added to
tailor the unit to suit the installation.
The design also allows for any unit to be re-engineered by
adding or removing components at any stage of the project
lifecycle to respond to changing requirements. This flexibility
offers significant cost savings over replacement of an entire unit.
This can be beneficial during the fit-out stage of a project where,
for example, changes in space usage can lead to reduced noise
criteria and the need to introduce attenuation.
Modules including a choice of inlet & discharge plenums
and attenuation. Return & fresh air plenums and an inlet
attenuator are shown.

Our Prestige Cheetah Fan Coil Units have
been specifically developed for residential and
hotel applications.
The units consist of the normal core unit, but also
incorporate our Prestige Discharge Plenum module. The
inclusion of the plenum adapts the unit for any scenario
where a rectangular discharge connection is required,
such as in hotels, residential apartments or an office
reception area.
In addition to providing a rectangular discharge, the
plenum also features a special acoustic lining which when
coupled with integrated attenuator modules can reduce
noise level values to as low as NR25.
Additional attenuation can be provided where very low
noise levels are required using the modular rectangular
inlet attenuators and extended length discharge plenums. Prestige rectangular discharge plenum
delivers noise levels as low as NR25
Low Noise Localised Air Conditioning is ideally suited to residential apartments
