Features
Slim and Compact
Design
Light and rigid construction due to the compact and strong
structural design of the unit. Slim unit design also fulfills the
stringent space requirement of today’s building design. High Air
Volume FCU with the height of only 430mm is most suitable for
application that demand for high air flow but with space saving in
mind.
High Efficiency
Heat Exchanger
High quality copper pipes with slit profile aluminium fins are being
transformed into high efficiency heat exchanger through advance
design, manufacturing equipment and processes.
Low Noise
Through stringent static and dynamic balancing tests of motors,
coupled with high quality thermal and acoustic insulation in the
unit, superb low noise performance is achieved.
Multiple ESP Options
Standard fan coil units come with low ESP (0Pa) and high ESP
(30Pa and 60Pa) options to suit different applications. High Air
Volume FCU comes with Standard ESP (40 Pa) and High ESP (130
Pa) options to add to the product line up.
Simple Installation
Unique design of the fan coil units allow easy on-site modifications
of water pipes configuration (left or right). Accessories are also
available to ensure trouble-free installation.
Easy Maintenance
The fan coil units are equipped with high quality electrical motor
with low noise bearing that do not require lubrication and thus
minimum maintenance effort required. Blowers and also motors
can be dismantled individually if cleaning of heat exchanger is
needed. High efficiency filter provides better filtration than
normal filter with longer operational life and easy to clean.
No Leakage
One piece molded drain pan with integral thermal insulation and
professional welding skill enable all condensate water to be
collected and prevent condensation at the outside of the drain pan.
Superior Product
Quality
All fan coil units are manufactured in a ISO9001:2000 and
ISO14000:2004 certified manufacturing facility whereby highest
products’ quality is always top priority. The products’ high quality
standard has been recognized through successfully obtaining the
CE marking certification which in turn comply with the stringent
EU requirements.

Engineering Specifications
General Data - Ceiling Concealed FCU (3 rows Coil) 50/60Hz
Note:
1) Nominal cooling capacity is based on the following condition:
a) Water temperature: 7.0°C (inlet) / 12.0°C (outlet)
b) Air entering condition: 27.0°C DB / 19.5°C WB
2) Air volume is tested under entering air condition of 20.0°C DB and dry coil condition.
3) All the units’ airflow value stated is at high speed.
4) Sound pressure level is based on 11.5 dB(A) anechoic room background noise.
5) The manufacturer reserves the rights to make changes to the above specification without prior notice.
