FLEXY
High-capacity reversible heat pumps for industrial and commercial applications
The FLEXY heat pump series has been developed to meet the heating demands of medium and high-capacity systems.
When designed as reversible units, FLEXY heat pumps can also operate in cooling mode.
As such, reversible heat pumps represent an efficient and reliable solution for covering year-round heating
and cooling energy demands of industrial and commercial systems.
FLEXY heat pumps use semi-hermetic reciprocating compressors designed and certified for operation
with flammable refrigerants. For precise capacity control and energy savings, compressors are controlled
by frequency inverters, while overall unit operation is managed by an advanced controller.
Air heat exchangers are manufactured with copper tubes and aluminum fins.
Axial fans equipped with EC motors enable variable speed operation, achieving outstanding energy efficiency.
The units are designed for outdoor installation.
Each FLEXY heat pump is factory tested and delivered pre-charged with refrigerant and oil.
Conformity assessment is carried out in accordance with the European Pressure Equipment Directive (PED) 2014/68/EU.
The unit complies with all safety and environmental requirements.
