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 fans are up to 70% more energy efficient at

providing the same duty when compared to equivalent AC

motor versions. This lower energy consumption means less heat

transferred into the airstream when the fan is running, and this

helps to maximise the cooling performance of the fan coil unit as

a whole.

Our EC fan coil units offer a typical energy saving of 60W per

fan. On developments using large quantities of fan coil units, this

energy saving may lead to significant savings in other areas, for

example reducing the cooling capacity of chillers in order to

minimise capital expenditure and running costs..

Compliance

All of the efficiency characteristics of Caice’s fan coil units

support compliance with the SFP limits in the 2013 revision of

Building Regulations Approved Document L. Our 300 series fan

coil units offer SFPs in the range of 0.20 to 0.40 W/l/s. EC fan motors can deliver typical energy

savings of 60 Watts per fan, compared

to equivalent AC motors

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 typical design temperatures for cooling (air on/off

23/12°C, chilled water flow/return 6/12°C), and 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.

We are also able to offer our units with an integrated low

cost controls package, enabling standalone and BACnet

operation.

Fan Coil Unit Size Sensible Cooling Duty

Size 1 1.71 kW

Size 2 3.00 kW

Size 3 3.91 kW

Size 4 5.24 kW

Size 5 6.35 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.

add or remove components at any stage of the project

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
