General description
The YLCA/YLHA units are high-performance air-water water
chillers and heat pumps using R-410A ecological refriger-
ant.
These units are designed for air conditioning or industrial ap-
plications 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
e lectronic controller to be used on air-water water chillers
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-ups. 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 RS485 monitoring network. For further informa-
tion, please see Operating Instructions.
The YLCA/YLHA units are made of proven quality compo-
nents and manufactured in compliance with standards in
force (ISO 9001 certification).
