EAS is an air-water heat pump with multicroll compressors. It is able to fully meet heating, cooling and domestic hot water production requirements with extremely high energy performance. Available in three versions:
H heat pump with reversible refrigeration circuit
C chilling-only chiller
F Free-cooling chiller

  • Multi-residential buildings
  • Stores
  • Factories

Maximum efficiency at partial loads

EAS features a multiscroll solution with single or dual refrigeration circuit options. The use of an electronic expansion valve, oversized plate heat exchangers, and modulation of water flow rates make EAS efficient in all conditions of use, including at partial loads.

Regulation and remote control

The control software supplied allows all the necessary adjustments to be made in order to maximize efficiency and configurability according to the different system types. The unit interfaces with any communication protocol, for the management and control of operations, even remotely.

Extreme modulation

Thanks to the possibility of installing the pumping groups inside the unit, the hydraulic flow can be modulated to maximize the system efficiency. The use of EC electronic fans allows complete modulation to be managed according to energy and acoustic requirements.

Technical overview

Technical specifications


EAS is equipped with high efficiency scroll compressors, and can be designed with single or double refrigerant circuit, improving efficiency at partial loads or operating redundancy.


EAS can be equipped with standard R410A refrigerant, or with the innovative low environmental impact R454B for maximum environmental sustainability. The use of the A2L ready kit consisting of refrigerant leak sensors and overpressure fans for the electrical control panel makes EAS safe even when slightly flammable refrigerants classified as A2L are used.


The electronically controlled expansion valve (EEV) maximizes EAS performance under any temperature condition, at both source and user end, to ensure consistent efficiency and versatility.


The use of panels to completely enclose the refrigerator compartment, the quality of the soundproofing materials used and the use of dedicated anti-vibration mounts to support the compressors make of EAS an ultra-low noise heat pump.
