1. Description
1-1. General description :
The Heat Exchanger (HEX) is designed for direct air to air heat exchange to remove the
heat from the cabinet . It is easy to be installed in the cabinet with the nuts.
(Recommended on the door of the cabinet)
The internal and the external air circulation loops of the HEX are separated to prevent
the introduction of dust, humidity and dirt. The fan on the external air loop conforms to IP55
protection rating.

1-4. Configuration & Maintenance
The HEX is composed of the key components as the following:
Chassis , Heat Exchange Core , Controller and Fan Tray , user can slide out the
fan tray easily for replacement of the controller and fans .
Item Q'ty Description
1 1 Chassis assy
2 1 Internal plate assy
3 1 External plate assy
4 1 Internal fan
5 1 External fan
6 1 Controller assy
7 1 Heat exchange CORE assy

1-5. Thermal path and Airflow baffle
With the forced convection using the axial fan , the warm return air generated by the
equipment will be blowing into the upper inlet and pass though the HEX core, the
temperature will be lower on the other side of the core. The cold supply air will be used
to cool down the system ; While on the opposite side , cooler air from the out
environment will be drawn into the lower inlet and bring the heat of the HEX core out
from the upper outlet . The thermal exchange path is shown in the figure below.

Switch "TEST / CLEAN"
When pressing the “TEST / CLEAN” button, both outer fan and inner fan will run from
low speed to high speed for testing purpose . The testing process is around 2 minutes, and
the LED of INNER FAN and OUTER FAN will be blinking in GREEN color.
When the fan failed, the LED will be blinking in RED . and it can be turned off by
pressing the “TEST / CLEAN” button again .
LED of "INNER FAN & OUTER FAN"
(GREEN) : Fan normal
(RED) : Fan failed
(Blinking GREEN) :Fan is normal during test
(Blinking RED) : Fan failed during test
LED of "STATUS"
(GREEN) : NTC normal at standalone mode
(RED) : NTC open or short at standalone mode
NTC position : J13 for choosing
Inner sensor (on control panel) or
External sensor (COMM port Pin7 & Pin8 )

Standalone control mode
HEX detects ambient temperature to control cooling capacity.
User can choose inner-sensor on panel or outer-sensor on cable to detect ambient
temperature by changing J6 jumper position ( inside of controller)
