• 30PA/PAC
Air-cooled water chillers.
• 30PH/PHC
Reversible heat pump units for operation in negative outdoor
temperatures (greater than -15ºC WB) for water heating and cooling.
Defrosting by reversing the cycle.
After manufacturing, all units are charged with refrigerant and
are tested at the factory, verifying the correct operation of all their
components within the operating range for which they are intended.
The units comply with European Directives: Machinery 2006/42/EC -
EMC 2014/30/EU - LVD 2014/35/EU - PED 2014/68/EC (Category 2)
- RoHS 2011/65/EU - Eco-design 2009/125/CE - Eco-labelling 2010/30/
EU; and with Harmonised Standard: EN 378-2:2012.
Those in charge of the installation, commissioning, operation and
maintenance of the unit must know the instructions contained in this
brochure and the speci
fi
c technical characteristics of the installation place.
The
30PA/PH
cooling only and reversible heat pumps are compact
outdoor air/water units.
Available in two versions:
• STD (Standard)
• HEE (High Energy Ef
fi
ciency)
These units have been made for operation indoors in the production
of hot and/or cold water, applicable to heating, cooling, and industry.
They are equipped with centrifugal fan (STD version) or electronic plug-
fan (HEE version), plate exchanger, hermetic scroll compressor, and
electronic control with microprocessor, components optimised for the
R-410A refrigerant.
This range is also offered with an integrated circulation pump:
30PAC/PHC
.
The entire range also has the option to include a desuperheater circuit
that allows for the production of hot water at a temperature greater than
in the condensation circuits.
