Belimo solutions for fan coils.Protect valuable resources.

Maximum comfort, minimal consumption.

Fine-tuned

to requirements

Fan-coil air conditioning systems call

for a special room temperature controller.

This device must not only control the

valves precisely, it must also support

multi-stage fan control. Simple opera-

tion and the option of individual over-

ride are further essential prerequisites.

Reconciling these diverse requirements

is no problem for the special fan coil

controllers in the EXT-F2000PS series:

fine-tuned to meet these specifications,

they interact optimally with the char-

acterised control valves.

Lower costs with

air bubble-tight closing valves

The 2 and 3-way characterised control

valves in the R2BR.. and R3BR.. series,

proven millions of times over, control

warm or cold water circuits precisely,

reliably and efficiently – in fan coils too.

Since the valves are always air bubble-

tight in the closed position, no leakage

occurs. They are motorised with com-

pact TR actuators, which are renowned

for their low energy consumption (0.5 W

in standby mode). This valve/actuator

combination generates a significant

reduction in overall energy consump-

tion and results in a short payback

period for the basic investment.

Allowing energy to circulate un-

necessarily when valves are closed

is something that is rightly frowned

upon today. The answer is surpris-

ingly simple: in conjunction with

Belimo’s room temperature con-

troller, characterised control valves

that are always air bubble-tight

in the closed position facilitate

energy-optimised control of fan-

coil air conditioning systems and

help protect the environment.

We set standards.

Save valuable energy

Because conventional globe valves

usually have leakage rates, up to 15

litres of cold water can easily circulate

unused per fan coil each year. For

1000 valves, this adds up to about

15,000 litres of cold water, which is

approximately equivalent to the volume

of a 3 x 5 m pool which is 1 m deep.

This can be prevented with Belimo

characterised control valves.

High consumption with

conventional control valves

High energy losses can be demon-

strated by the example of an air condi-

tioning device with 2.5 kW of power and

a throttling circuit on the valve side:

The supply is 6°C, the return 12°C and

the set point 22°C. This results in an «a

value» of 0.23. The valve was designed

with a valve authority (PV) of 0.5. The

fan coil is in zero-load operation (valve

closed) for 2000 hours per year. The

energy loss for a conventional globe

valve can be as high as 16 kWh / year

(for a typical leakage rate of 0.05% of

the kvs value). Practically, the valve

authority PV will end up being even

smaller, i.e. the energy loss increases

to 20 kWh / year and fan coil with a

PV of 0.3.

More efficient with Belimo

characterised control valves

These energy losses are avoided when

air bubble tight closing characterised

control valves from Belimo are used.

With energy costs for cooling being

about € 0.06 / kWh, the savings per fan

coil in ten years are about € 10.00. For

1000 units, then, there is a savings

potential of € 10,000.
