Technical Description:

  1. External static pressure of the machine in this manual does not include the dynamic pressure of the air outlet included in the residual pressure of the previous version.
  2. 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.

Technical Performance/Fresh air condition of GK Series Vertical Fan Coil Unit

※ Cold fresh air condition: Air inlet’s DB/WB: 35℃/28℃, water inlet/outlet: 7-12℃

※ Heating fresh air condition: Air inlet temperature 7℃; Hot water inlet temperature 60℃; Water volume is the same as refrigerant.
