Technical Data
General Description
The Duct Fan Coil is designed to meet and exceed the demanding requirements for efficiency and quiet operation.
STRUCTURE
Structure is made from electrostatic coating steel panels completed with couplings for the connection of ducting and gravity
drain condensate pan with insulation. Fire resistant insulation is fitted internally to provide both thermal and acoustic
insulation. Insulation is fitted on the top of coil.
COILS
Constructed with seamless copper tubes and headers. The tubes are mechanically expanded into corrugated aluminum fin
material for a permanent primary to secondary surface bond. Coils are tested at 25 bars and recommended for maximum
operating at 16 bars. Coils include manual air vent and water purge valves.
FAN
The forward-curved centrifugal fan is statically and dynamically balanced for quiet operation. Fan impellers are made from
metal.
AC MOTOR
Standard motors are PSC, permanently lubricated type with internal thermal overload protection. The unit is using 3-speed
AC motor.
AIR FILTER
The filter is easily removable and washable and is made from self-extinguishing acrylic with a class EU2 (G2) (Merv 2-4)
efficiency rating. G4 or F8 (Merv 8, 14) efficiency filter is optional.
DRAIN PAN
The drain pan fits a drain pipe of Ø 21mm (on both left and right side of drain pan) and is with fire resistant insulation.
Complete Function Control (AC-S1 type)
The PCB (printed circuit board) Modbus microprocessor controls functionality of the indoor fan motor, water valves
(ON/OFF) and electric heater (optional), to maintain room conditions at a user-defined set point. Temperature settings, fan
speeds and other control functions can be changed by either infrared handset or wired wall pad controller.
Terminal Strip (T1 type)
A 230Vac relays board is used to drive 3-speed AC motor. 40VA (24Vac) transformer is optional which supplies power to
thermostat and modulating valve.
Terminal Strip (T2 type)
A 24Vac relays board is used to drive 3-speed AC motor. 40VA (24Vac) transformer is optional which supplies power to
thermostat and modulating valve.
