Casing:
•The box body is made of galvanized steel plate, the load-bearing parts are designed with stiffeners, and the fixed hole position is stretched to prevent deformation;
•The whole machine is well sealed to improve air cleanliness;
•Rear return air and bottom return air can be freely exchanged;
•Flocking cotton is pasted at the air outlet, top plate, side plate and bottom plate to prevent cold bridge and condensation.

Coil：
•High quality seamless copper pipe (copper content > 99.99%);
•Louver type hydrophilic aluminum heat radiating fin (the hydrophilic coating base is provided with resin anti-corrosion coating);
•Mechanical tube expansion technology makes copper tube and aluminum sheet closely combined to strengthen heat exchange;
•Large U-bend process to reduce coil solder joints;
•V-shaped design, increase heat exchange area, improve heat exchange efficiency and reduce unit noise;
•Countercurrent design of water flow to improve the heat exchange efficiency of coil.

Drain connecting pipe：
•The special connection form of the pipe makes the pipe fixing more precise and convenient;
•Built in condensate water channel to prevent condensate from dripping into the ceiling.

Exhaust valve:
•The built-in exhaust valve makes the exhaust easier;
•The discharged water flows directly to the condensate pan in the unit, and the condensate flow is placed to the ceiling;
•The exhaust valve is set at the highest point inside the unit for more thorough exhaust;
•There is no need to set an exhaust valve on the top of the water pipe, which is more convenient for insulation.

Water Tray：
•The water tray is made of B grade flame-retardant polystyrene foam material, and the heat conduction coefficient is 1‰ of the traditional carbon steel water plate.
•The inner surface of the drainage pan is also attached with a layer of thermoplastic film to improve the thermal insulation effect and eliminate the phenomenon of condensation on the outer surface.
•The drainage pan adopts built-in design, which does not occupy extra space.
•The outer edge of the sealing strip, good assembly sealing;
•The inner edge of the water pan is slanted, and the water tank is set inside, so that the water is drained smoothly.

Drain pump(optional):
•Optional drainage pump, head of 750mm;
•The installation of the drainage pump adopts an integrated detachable design for convenient maintenance;
•The unit can be added with water pump according to the installation situation on site.

High efficiency motor:
•AC motor/permanent magnet brushless DC motor: high efficiency, low noise, can achieve three speed control/stepless speed control;
•The motor is fixed on the top surface, which is more stable;
•The fixed mode of motor and fan can reduce the noise generated during operation;

Fan:
•The fan impeller is a multi-wing centrifugal blade with high efficiency and low noise.
•Material is ABS engineering plastic;
•Special C-type cochlear tongue design, lower sound energy;
•The volute is of split design, which is convenient for unit maintenance.

Intelligent control (DC brushless type):
•The realize master-slave control, and a single wire controller can control more than one FCU unit.
•Equipped with communication interface, can be connected to the building automatic control system, remote control;
•PID proportional integral constant temperature control technology;
•A variety of control mode options: including refrigeration, heating, dehumidification, ventilation, automatic, sleep, timing switch, etc.
