GENERAL - HH
Comfair HH fan coil units are designed to operate against higher external static pressures (from 105 to 260 Pa), and are available in
7 sizes.
All standard units can be supplied with a complete range of factory or site fitted accessories, allowing a multitude of configurations
for all typical applications, for example :
• auxiliary condensate drain pan (UTC)
• air Filter section (SFA)
• auxiliary Coil
• fresh air inlet damper (SSP)
• electric heater (SRE)
• inlet, supply and exhaust air plenums (PAM, RAM et BAM)
FAN SECTION
Composed of one or two double inlet centrifugal fans with aluminium blades, mounted in horizontal position and statically and
dynamically balanced. The electric motor is fitted with overload protection and has three speeds. It is constructed to comply with all
relevant International standards, with a capacitor permanently in circuit. Motors are connected directly to the fan shafts and are located
on anti-vibration mounts to ensure particularly quiet operation.
CHASSIS
The chassis is manufactured from thick (1mm) galvanised sheet steel.
COILS
Water Heat exchangers are copper tubes with aluminium fins, bonded to the tubes by a mechanical
expansion process. Coil connections are of female type antitorsion and headers are fitted with easily
accessible air-vents.
CONTROL PANEL
Comfair HH fan coil units must be controlled from a separate remote controller. A large selection of controllers
with varying levels of function is available to satisfy most requests.
Options delivered separately : Ambient Thermostats (TA), Minimum water temperature thermostat (TC),
Remote (wall mounted) controllers (CD1, CD2/X1, ... ).
AIR FILTER
Simple to remove, it comprises a metal frame containing a washable acrylic filter media (filtration efficiency EU 2).

MANUAL FRESH AIR INLET DAMPER
Produced form Alu-Zinc sheet metal, it allows the introduction of fresh air up to a maximum of 30% of the total air volume.
ELECTRIC HEATER
Electric heater elements meet all of the relevant International safety standards and are fitted as standard
with a safety cut-out thermostat and automatic reset. Heater elements are factory fitted with all electrical
wiring and are connected to the control panel via a contactor.
AUXILIARY COIL
In order to offer the best solutions for 4 pipe applications, a supplementary 1 row coil can be ordered
factory fitted.
INLET, SUPPLY AND EXHAUST AIR PLENUMS
Plenums are constructed from galvanised sheet steel allow for easy connection to ductwork.

Data given for medium water temperature at 9,5°C
3 WAYS VALVE
Using of 2 or 3 ways valves is compulsory when the unit is used for cooling to avoid condensate in the external structure (bearing
structure and cabinet). As alternative install a regulating system to stop coil water entering when the fan is off.
When the units is connected with ducts fan air flow is reduced due to the ducting pressure drops.
With very high pressure drops fancoil air flow becomes too low and electric motor which is connected to the fan can be damaged. For
this reason we recommand static pressures lower than the maximum limit static pressures indicated in the schedule.
NOTE: When the fancoil is operating with the maximum operating indicated static pressure value, air flow is half in comparison with
the unit without ducts at the same working speed. Definitively the static presure limit corresponds to the back pressure ables to half
fancoil air flow (as a consequence the fancoil unit performances like heating & cooling capacity, will be reduced of about 50%).
