1.1.2 General description of the unit
The YLCD/YLHD units are high-performance air-water coolers and heat pumps with centrifugal fan that
use R-410A ecological coolant.
These units are designed for air conditioning or industrial applications that require cold or hot water and
air pressure available for installations with ducts.
They are silent and compact units, equipped with vertical or horizontal discharge centrifugal fans, that
can be installed indoors and that accept outdoor installation.
They are available in two versions: with and without a hydro kit, which includes a buffer tank (except size
25) and a high head pressure pump.
The control system of these units is a specially programmed electronic controller to be used on air-water
coolers and heat pumps equipped with tandem compressors (except size 25). Easy to use and safe,
these units precision control the water return temperature of the installation, carry out defrost cycles and
control the start-up of the compressors, as well as the pump and electric resistors. By reading the control
probes and safety elements, the controller protects the entire equipment against malfunctions. The
system allows connecting the unit to a standard RS-485 monitoring network.
For further information, please see Operating Instructions.
The YLCD/YLHD units are made of proven quality components and manufactured in compliance with
standards in force (ISO 9001 certification).
