1.4. Main Components
1.4.1. Indoor Unit
Liebert SRC-G indoor unit consists of evaporator, EC fan, thermal expansion valve, filter dryer, and and Surge
Protective Device (SPD). For optional component details, refer to Section 1.5.
• Cabinet
The cabinet of the unit is prepared by steel sheet of 1.2 mm thick, which is custom powder coated to protect
against corrosion with the air-stream insulation thickness of 10 mm; color code of the unit is RAL9005.
• Evaporator Coil
Evaporator is a hydrophilic coated fin-tube heat exchanger with high sensible heat factor (>0.9). The distributor
is designed and verified according to ensure that the refrigerant (R410A) is distributed evenly in each loop,
improving the eiciency of the heat exchanger to a great extent.
• EC Fan
The unit is fitted with one/two direct-driven, high eiciency, single inlet, backward curved, centrifugal ‘plug’ type
fan (s), with aluminum nozzle (s) and PA Plastic impeller (s). The fan motors are Electronically Commutated (EC),
IP54, with internal protection and speed regulation via controller signal. The fans are statically and dynamically
balanced.
