Microchannel coils are 40% smaller, 40% more eff icient, and use 50% less refrigerant than standard tube and fin coils.
Multiple micro channels improve heat transfer.
Flat tube results in lesser air side pressure drop, less power consumption.
Compact design & less also resulting in reduced unit weight.
Necessary for integrated and optimal variable capacity control.
Maintain constant superheat
EEV is standard feature in PEX3
The unit is equipped with high efficiency, single inlet, reserve curved, centrifugal plug type innovative EC fan(s).
The EC fan technology regulates airflow and reduces the fan input power. In-floor configuration further reduces energy consumption in downflow units.
Liebert EC 2.0 fan modulates the fan speed according to load density; saving nearly 30% of energy consumption
PEX3 has a footprint nearly 15~30% lower than other brands, available in 4 frame sizes.
PEX3 DX is available from 30kW up to 100kW both down flow and uplow configurations.
PEX3 technology enables close monitoring and control of room temperature, the standard version includes advanced controller, heater, humidifier and other components.
