ABOUT FINPOWER
We at Finpower, were born out of sheer need of quality and
affordable HVACR equipment for the ever-growing
markets. Established in 2011, we strive to specialize in
manufacture of Air-conditioning and Kitchen Ventilation
equipment at the state of the art manufacturing facility at
Dubai (UAE) and Mangalore (India).

ABOUT FAN COIL UNITS

Fan Coil Units or FCU is a device used in a building to heat
or cool a specific space. It is essentially made up of a motor
with a fan, a heating or cooling coil connected to the
building’s central hot water and cold water system, and
valve with a controller. In simple terms, it is a heat
exchanger where the fan and motor brings air, which is a
medium of transfer, to the copper coil. The coil is either
having hotter or colder water so transfers the heat to the
flowing air. This catalogue displays ceiling hideaway ducted
type, exposed double skin and decorative type of units
ranging from airflows of 200 CFM to 3000 CFM.

MAJOR COMPONENTS
Motor
1. AC Motor (Standard Feature)
Motors are 3 speed permanent split capacitor type suitable for a
power supply of 220-240V / 1 ph / 50 -60 Hz. It is wound with
class Binsulation and the shaft rotates on a permanently
lubricated ballrace bearing which in turn rests on an
anti-vibration rubbermounting. Resilient mounted motor are IP
rated i.e. IP20 and higher
IP can be provided to make the specification on motor which are
built with thermal protection. Motors meet all the requirements of
CE with explosion proof capacitor. Motors are provided with
composite material conduit. All the motors comply to EN 60034-1.
This design gives the motor a smooth trouble free long life of 10
years.
2. EC Motor (Optional Feature)
Our green EC motor adopt “sensor less FOC (Field Oriented Control)
drive technology”, which omits the physical hall-effect sensors that
must be installed inside the motor to detect the rotor’s position,
therefore, it is free from the risk of hall-effect sensors’ failures,
making EC motor more reliable and durable, and also making the EC
motor and driver more cost effective.
• EC fans with integrated, active power-factor correction.
• Efficiency – The driver’s efficiency is up to 94%
• Precise Speed Control – Excellent control ability at ±5rpm speed
control.
• Protections – Rotor lock protection, current protection, power
module temperature protection.
• Motor can be stepless i.e. fan can be operated from 0 to 10v
based on room load or 3 speed controller is fixed outside for easy
controller access.
Specifications:
• Nominal Voltage: AC 230V, Frequency: 50/60 HZ.
• Input Signal: 0-10 Vdc or 3 speed.
• Ingress Protection: IP 54
• Class B insulation as per site requirement.

MAJOR COMPONENTS

Copper coil
Coils are provided in all fan coil units and are made up of 3/8” OD copper
tubes with mechanically expanded aluminum fins as a standard. The
design emphasizes on the need of minimum air side and waterside
pressure drop yet provide a highly efficient heat transfer. Various options
are available on coils depending on the application. Coils are provided with
air vent and drain plug for ease in commissioning and maintenance
respectively. The coils are tested as per ASHRAE STD 33 & tested for
performance with complete FCU’s i.e. AHRI 440.

Return Air Plenum

The return air plenum is provided as standard. All return air is brought into the unit through single side where
the filter is mounted. Thus filtered air enters the unit keeping the coil clean for efficient heat transfer. The
plenum also reduces the sound transmission through the motor and hence is insulated with class ‘O’ fire
retardant nitrile rubber insulation.

Fan
The unit is fitted with Double Inlet Double Width (DIDW)
centrifugal, forward curved galvanized steel impeller. The
volute housing is made of Galvanized steel giving it a
rugged construction. The impellers are statically and
dynamically balanced as per AMCA 204 before enclosing in
the housing.

Filter:
All the units are provided with high efficiency Nylon mesh woven media
filter as standard. These are cleanable by water or compressed air and
have long life. For higher efficiency we provide options of G2 or G3 grade
filters, however, the performance has to be rated accordingly. The filters
are tested as per ASHRAE 52.2 - 2017.

Filters come with standard lift up option, which is easy for removal &
maintenance. However, optional filter frames with bottom, side or top
removable access shall be provided on special request. Filters in split can be
provided where access is constrained.

4
 MAJOR COMPONENTS

Drain Pan
Drain pan are manufactured in house with steel & corrosion resistant Epoxy coated
steel drain pan with 6mm nitrile class O insulation. We provide SS304 / SS316 along with
10mm, 19mm insulation as option. Drain pans are provided with drain nipple to ensure
all the water is flow out & designed as per ASHRAE 62.1.

Return Air Plenum

Casing
Casing
The unit is constructed out of heavy duty galvanized steel
complying ASTM A613. Anchor holes are provided at the top
of the unit for hanging the unit safely. The casing is
designed for an efficient sealing of air and water so that
neither of them get mixed apart from heat exchange area.
Units are by default with internal thermal and acoustic
insulation to prevent any heat transfer and sweating.

Electric Heater
• Finned tubular Electric heating elements with auto reset thermal cutout can be provided inside the FCU for
sensible heating
• Duct heaters with necessary safety like Auto reset thermal cutout, manual reset thermal cutout and airflow
switch can be provided as additional fitment over the FCU for humidity control. The heaters are designed and
arranged in the most efficient pattern for heat transfer.
• Different control options can be provided like stage, thyristor etc in the control panel of duct heaters.
Hot water coils
• Single row or two row are included in i.e. 4 pipe system for hot water coil where ever the hotwater is available
for heating.
• This are constructed out of 3/8” OD copper tube with aluminum fins with fin density of 9-10 FPI with brass
connection.
• Hot water coils are used for sensible heating to maintaining the room temperature in cold regions or winter
application, alternatively are used to maintain the humidity levels in the condition space.

UV Lamps
• Ultra-violent lamps can be provided after the cooling coil so that their radiation will ensure to eliminate the
bacteria and reduce the formation of algae on the coil surface and other exposed area.
• Having coverage area of 72- 125 µW/CM² at 254 nm with minimum power consumption, the UVC lights are great
protection for various air borne diseases.
• UVC lamps are designed based on average life of 16,000 hours based on standard air quality and steady power
supply.

FAN COIL UNIT - CB SERIES
CABINET TYPE - Decorative

Finpower cabinet fan coil units are commonly known as decorative units, which are designed for exposed installation, longer lifetime under normal
running conditions. Units are made with pre coated GI sheets on all the four sides leaving the return and top area. Sheet metal work is done
aesthetically leaving sufficient space on both sides for access and terminations. Units are also provided with double deflection grill to direct the
airflow.
The unit is coated with sheet which are tested a per ASTM B-117. Cabinet fan coils incorporate metal fans that are quieter than usual and require
less fan power. This fan of metal construction blades provides excellent corrosion resistance and durability with continues year round operations.
The motor provided is energy-saving permanent split capacitor type motor and is resiliently mounted. In order to accommodate increasingly tough
electrical safety requirements and ease of maintenance, the capacitor is placed over motor enclosure. The motor lead out wires are sheathed and
also protected by flexible conduit.

SOFTWARE STRENGTH
Fan coil unit selection software facilitates the preparation of high-quality, well-presented quotes for fan coil units quickly and efficiently.

Based on available options for a FCU, we choose a model and select a coil. We also select the air and water parameters for that model. Once we
have done that, we will be able to run a calculation of coil performance. Coil performance calcuation is initaited as a following step which include
the leaving air and water conditions, cooling and heating capacity, and fan power consumption. Calculations are based on the test results available
and correction factors.
