Product Overview

1.4.2.Plate Heat Exchanger

The unit is equipped with a water-refrigerant heat exchange brazing plate. This plate heat exchanger has a

special heat exchanging channel, which features higher heat exchange efficiency, higher compact pattern, lower

pressure drops, greater cooling capacity, corrosion resistance, and safe and leakage-free operation.

The system facilitated with a large-capacity fluid reservoir to store enough refrigerant. Three fluid sight glasses

at the side of the reservoir are used to observe the internal liquid level. The safety valve on the top is used to

safely relief the excess pressure, thus ensures stable and reliable operation of the system.

The system equipped with a well-known brand two-port valve with an equal flow percentage. A large-torque

valve actuator is also installed to achieve the valve opening in real time, that ensures accurate and reliable water

flow regulation. By default, the unit is configured with the two-port valve.

The Liebert XDP precision air conditioner is equipped with a microprocessor controller that adopts the advanced

PID based technology. Multi-level password protection can effectively prevent unauthorized operations. The

microprocessor controller provides the self-recovery function against power failure. The runtime of major

components can be accurately understood through the menu. The professional-level fault diagnosis system can

automatically display the current fault and facilitates easy device maintenance. The microprocessor controller

can store up to 2000 historical events. The microprocessor controller provides RS485 interface and can also

adopt the Modbus protocol.

The 7-inch LED color screen supports sensitive touch, tree-type menu, user-friendly screen, and simple

operation. User can view the operational status and parameters of the XDP and the cooling module in real time.

By configuring the RS485 interface, the system can store up to 2000 historical events.

1.4.7.Variable Frequency

The variable frequency controller controls the pump frequency in a variable manner, accurately adjusts the

refrigerant flow, and communicates with the main controller. It timely uploads alarm information and protects the

system. This feature helps in reliable operation.
