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. 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. 1-2.

Mounting panel cutout TOLERANCE : 0.5MM Page 4 Part no. : Delta model no. : HEX060PA 1-4. Configuration & Maintenance The HEX is composed of the key components as the following : Chassis , Heat Exchange Core , Controller and Fan . The user can disassemble screws for controller and fans replacement . Item Q'ty Description 1 1 Chassis assy 2 1 Frame assy 3 1 Controller 4 1 Internal fan 5 1 External fan 6 1 Heat exchange CORE Page 5 Part no. : Delta model no. : HEX060PA 1-5. Thermal path and Airflow baffle With the forced convection using the axial fan , the warm air generated by the equipment will be blowing into the internal return opening and pass though the HEX , then flow out from internal supply opening , 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 from the external air inlet side and bring the heat of the HEX out from the external air exhaust side . The thermal exchange path is shown in the figure below. Page 6 Part no. : Delta model no. : HEX060PA 2. Electrical specification 2-1.
