dydronic ceiling concealed fan coil unit 2 pipe & 4 pipe

Fan Coil Unit

Ceiling concealed fan coil unit: 

General Features: 

1. Casing: Adopt high quality galvanized steel with 0.7mm thickness for top plate and bottom plate. 1mm thick galvanized steel adopted for coil end plate and fan motor deck plate to guarantee unit strength. Complete 1mm thick casing is for option

2. Coil: Adopt OD9.52mm inner smooth seamless copper tube and blue fin expanded together, coil is designed by coil selection software and tested in factory performance test lab under 2.8MPa to guarantee the performance. Coil design is counter flow which makes higher efficiency.

3. Coil header: Adopt high quality brass with good design of less water pressure loss. Air vent is factory built in on the header part. Coil header connection protect mounting bracket is factory installed as standard to protect header not easily to be damaged during tube connection to the header

4. Fan blower: Adopt forward curved blades centrifugal galvanized steel fan blower which is dynamic and static balance tested.

5. Motor: Adopt single phase three speed capacitance type motor with easy capacitor maintenance design with 100% incoming test

6. Plenum: Adopt high quality galvanized steel with 0.7mm thickness for top, bottom and side plate. 1mm thick plenum is for option

7. Supply &Return air flange: Adopt high quality galvanized steel with 0.7mm thickness .1mm thick flange is for option.

8. Filter: 3mm-5mm thick Washable nylon filter is for standard. Other types and thickness of filter such as pure aluminum filter or sandwich style filter is for option

9. Drain pan: Standard drain pan adopts High quality carbon steel plate a molding ensures no wielding point and fully insulated by 5mm PE. SUS drain pan or extended drain pan is for option

10. Insulation for casing: Adopt 10+7teeth PU for the coil top plate. Complete insulation for casing and plenum is for option

4 way fan coil unit: 

General Features: 

1. Casing: Casing is made of high quality zinc coated aluminum. Thanks to an integrated blister process ,ensures there is no any water leakage because of no welding points. It adopts EPS material overal foaming and bonded to the drain pan.It looks elegant and light thanks to adopting much non metal material. The condensate area are double insulated

2. Front panel: 4 way air supply, intake grill,panel frame and adjustable air distribution louver on each side made from ABS.

3. Coil: Coil is designed by coil selection software and tested in factory performance test lab to guarantee the performance.It adopts Integral type "C" shape design of heat exchanger with high density without interval which makes the internal air temperature even avoiding area temperature difference caused by internal air twice non even mixture led by twice bended coil design. Coil design is counter flow which makes higher efficiency. Coil is made of high quality φ 9.52 mm copper tube and high efficient hydrophilic coated aluminum fin. It adopts advanced tube expanding process which makes the copper tube and the fins touch each other in best way and moreover big diameter and low noise fan blower is adopted to make sure the best heat transfer efficiency. The header is made of brass and thanks to the design, the water flow distributes even and less head loss is achieved which improves the heat exchange performance. Thanks to the good matching of the fan blower and the new designed air deflector, the performance has been improved 15%.

4. Condensate drain pan: Adopt blister process and it will be bond together with high condensity E foam drain pan at an organitic whole after heated. The drain pan and EPS foam both adopt anti fire material

5. Condensate drain pump: Adopt intelligent high lift condensate water drainage pump can make the water height of 750 mm which makes it more convenient for the setting of drainage pipe and ensures good drainage performance

6. Motor: Adopt large diameter vortex centrifugal fan ensures low noise running and energy saving. Adopting three-dimensional large dip angle spiral blades and rolling bearing motor. 7. Motor shaft adopts antirust processed hardened and tempered steel which ensures longer service life, high efficiency and low noise. Moreover good EPS foam is helpful on noise absorbing. There is anti vibration devices are adopted under motor.

8. Automatic swing: the operation of 4 pieces of swing louvers are controlled by separately four stepping motors,more reliable than one stepping motor linked control structure.

9. Blower: Single air inlet radial fan,fan assembly mounted on anti-vibrating supports guarantees extremely quiet. Filter: Adopt Nylon filter with easy remove design.

10. Control system: flexible control way,standard remote handset control(wired wall pad and modbus function are optional) .

11. Fresh air inlet can be reserved: fresh air from outdoor can be introduced into room which improves the indoor air quality
