Chapter 1 Overview
This chapter introduces the classification and models, model description, main components and technical parameters
of the Liebert.PEX condenser (condenser for short).
1.1 Classification And Models
The condenser is classified into two types: single circuit and dual circuit. The single circuit has a set of discharge/liquid
pipe to match the single refrigeration system of indoor unit. The dual circuit has two sets of discharge/liquid pipes to
match the two separate refrigeration systems of indoor unit.
The condenser is available in 17 models. The classification and models are listed in Table 1-1.

1.3 Main Components
The main components of the condenser include the heat exchanger, fan, fan speed controller and pressure sensor.
The heat exchanger is inside the condenser, and the appearance and position of other components are shown in
Figure 1-2 and Figure 1-3.
