Remark: The static pressure outside the machine in this manual does not include the dynamic pressure of the air outlet included in the residual
pressure of the previous version.
The heat and water volume of the eight-row surface air cooler is 1.50 times that of the four-row unit, and the water resistance control is ≤60 kPa.
Unlisted list due to limited editing.
Remark: WR(water resistance); WV(water volume)
Technical Performance/Fresh air condition of DK Series Ceiling Cabinet Type Fan Coil Unit
※ Cooling fresh air conditions: Air inlet’s DB/WB: 35℃/28℃, water inlet/outlet: 7-12℃
※ Heating fresh air conditions: Air inlet temperature 7℃; Hot water inlet temperature 60℃; Water volume is the same as refrigerant.

◆ Technical Description:
- In the above chart, the DK100II to DK200II series models can reduce the height of the unit according to actual requirements, but the corresponding machine width will be widened in the same proportion.
- The standard model of refrigerant water inlet/outlet pipes and condensate pipes are externally threaded, and the pipe diameter can meet the water requirement of pure return air condition, and can also meet the new wind conditions.Requirements.
- The dimensions of the above unit are suitable for 4 row, 6 row and 8 row surface air coolers.
- The height of the chassis marked in the installation drawing is 40mm. It is suitable for models below DK150 (included). The bottom frame larger than this model is channel steel with a height of 80mm.
