LHE high-efficiency air/water heat pumps are particularly suitable for applications where maximum efficiency in heating mode and a low noise level are required. The units are specifically designed to provide the best efficiency in heating mode; they can operate at outside temperatures down to -20°C and produce water up to a temperature of 60°C.
All sizes are supplied with reverse cycle valve used for winter defrost; the RV versions are also able to produce cold water in summer period (not available for HH versions).

The LSA/HP water chiller range has been designed for small and medium residential and commercial applications.

They are suitable for generating chilled water at 7°C, commonly used in applications with fan coils and/or air handling units.
LSA/HP water chillers have high operating efficiencies and are quiet in operation.

Differing versions and a wide range of accessories, enable the optimal solution to be selected.

The LHi series high efficiency air/water heat pumps are particularly suitable for applications with radiant panel heating systems or for those applications where maximum efficiency in heating mode is required.

The units have been specifically designed to have the best efficiency in heating mode, they can operate up to outdoor temperatures of -20°C and produce water up to a temperature of 60°C.

All models are also equipped with reverse cycle valve for winter defrosting function; the HH versions are designed for hot water production only and are suitable for tax deductions in countries where there are specific regulations for the use of heat pumps as heat generators.

The RV versions are capable of producing chilled water.
The XL versions also have an extremely low noise level thanks to the use of a special floating vibration dampening system that allows a noise reduction of about 5-7 dB(A) (optional).

The LZTi series of high efficiency heat pumps has been specifically designed for use with radiant floor heating systems or those applications where it is necessary to have maximum efficiency when heating.

They have been optimized on heating mode, are able to produce water up to 65°C and can operate down to -20°C ambient temperature.

LZTi units are available in 2 or 4 pipe (SW6) versions. Both versions can produce domestic hot water, in the standard LZTi through the activation of an external 3-way-valve and in the SW6 version by means of a separate heat exchanger and hydraulic circuit for the domestic hot water.

All models are supplied as standard with a reversing valve for defrost and cold water production in summer.

The LHA series of high efficiency heat pumps has been specifically designed for use with radiant floor heating systems or those applications where it is necessary to have maximum efficiency when heating.

They have been optimized on heating mode, are able to produce water up to 60°C and can operate down to -20°C ambient temperature.

All versions are supplied with reverse cycle valve used for winter defrost; the HH version is suitable for use in those countries that have support schemes for use of heat pump technology for heating. The RV versions are also able to produce cold water. The HH heating only versions is factory set and locked to operate only in heating mode whilst.

The noise is extremely low thanks to the use of a special floating vibration damping system which allows a noise reduction of about 6-8 dB(A) (Optional).

The LZT series of high efficiency heat pumps has been specifically designed for use with radiant floor heating systems or those applications where it is necessary to have maximum efficiency when heating.

They have been optimized on heating mode, are able to produce water up to 65°C and can operate down to -20°C ambient temperature.

All versions are supplied with reverse cycle valve used for winter defrost; the HH version is suitable for use in those countries that have support schemes for use of heat pump technology for heating. The RV versions are also able to produce cold water. The HH heating only versions is factory set and locked to operate only in heating mode whilst.

The noise in XL and NN versions is extremely low thanks to the use of a special floating vibration damping system which allows a noise reduction of about 6-8 dB(A).

The air source high efficiency heat pumps WZT series, in the NN configuration, are particularly suitable for those applications where it is necessary to have maximum efficiency in heating mode and a noise level extremely low and, for this purpose, are provided in two sections, linked together by refrigerant lines, installing the compressor in the internal section.

The units have been designed specifically to have the best possible efficiency, they may operate down to ambient temperatures of -20°C and produce hot water up to 65°C.
The units are available in 2-pipe (P2S, P2U), version 2 + 2 pipe (P4S), and in version 4 pipe (P4U).

The units P2U are not able to produce sanitary hot water, the P2S versions are able to produce domestic hot water through the activation of an external 3-way valve (not supplied), while P4S versions and P4U too are able to produce hot water regardless of the mode unit is operating, through the activation of a specific refrigerating circuit. All models are equipped with reverse cycle valve for winter defrost mode, RV versions are also able to produce cold water in summer (not available for HH version).

The noise level is extremely contained thanks to the use of a special floating system vibration damping that enables a reduction in terms of noise about 6-8 db (A) of compressors side and the fans in the combination with the specific number of turns extremely low (about 450 rpm).

WZA heat pumps are particularly suitable for applications that utilise well water or ground source probes.
These units have been designed for use with radiant floor heating systems or those applications where it is necessary to have maximum efficiency when heating. They have been optimized on heating mode and are able to produce water up to 60°C.

WZA heat pumps are available in several versions. The most simple is a 2 pipe unit that can provide heating only. By fitting an external 3 port valve the unit can provide either heating or domestic hot water. There is also a 4 pipe unit that produces domestic hot water in a separate hydraulic circuit and can generate this irrespective of whether the unit is in heating or cooling mode.

Differing versions and a wide range of accessories, enable the optimal solution to be selected.

There is also a 4 pipe unit that produces domestic hot water in a separate hydraulic circuit and can generate this irrespective of whether the unit is in heating or cooling mode. All the WHA units are also available in Free Cooling (FC) versions which provide low energy cooling by simply using the cool water that is available from either the ground source probes or the well water.

Differing versions and a wide range of accessories, enable the optimal solution to be selected.

WHK heat pumps are particularly suitable for applications that use source energy at medium or high temperatures.

These units have been designed to produce water at high or very high temperature for applications where it is necessary to have maximum efficiency in heating.
The units are available in heating only mode and can produce water up to 78°C (HT version).

A wide range of accessories allows you to choose the optimal solution.
