1.1 General description of the unit
The YLCA/YLHA units are high-performance air-water chillers and heat pumps using R-410A ecological
coolant.
These units are designed for air conditioning or industrial applications that require cold or hot water.
They are silent and compact units, equipped with vertical air discharge axial fans, that can be installed
directly outdoors.
They are available in two versions: with and without a hydro kit, which includes a buffer tank 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. Easy to use and safe, these units precision
control the water return temperature of the installation, carry out defrost cycles, modulate fan speeds
and control compressor, pump and electric heater start-up. 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 YLCA/YLHA units are made of proven quality components and manufactured in compliance with
standards in force (ISO 9001 certification).
