Low temperature air-water heat pumps

Highly efficient devices for commercial and industrial use, equipped with Scroll EVI technology and modern design with Flat top fan installation, are intended for a wide range of applications and operating conditions (from -25°C
to 45°C).

The units meet the energy requirements specified in the regulations for Energy-related Products (ErP) and have high seasonal efficiency coefficients. Additional energy configurations are available in the selection software.

Technological advantages

HP Dynamic Setpoint – smooth control of high pressure depending on the load maximizes energy efficiency. Electronic control of the injection of the evaporator expansion valves increases the efficiency of the exchangers.

ACS – ALPENTA Control System – dynamic high pressure setting value and several limiting functions maximize efficiency at part load and in outdoor conditions close to operating limits.

ASS – ALPENTA Selection Software – allows you to design hundreds of energy configurations so that the device meets individual requirements for energy efficiency or other specific technical requirements of the project.


Scroll EVI – higher efficiency of the cooling circuit with vapor injection technology (Enhanced Vapor Injection) with economizer. Heat pumps can work with higher efficiency at low outdoor temperatures down to -25 °C.

RS485 Modbus for cooperation with the superior system, automatic data recording on microSD and the possibility of extension with the Mater/Slave function.

Flat top EC – best performance
in its class. The fully integrated EC fans have been developed using CFD (advanced flow simulation) and ensure optimal air flow on the suction and discharge side of the impeller along with noise reduction.
