Description

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).

Versions

  • HH Heating only
  • RV Reversible heating/cooling
  • LS Low noise
  • XL Super low noise
  • P2U 2 pipe systems without domestic hot water production
  • P2S 2 pipe systems with domestic hot water production by external 3 way valve

Description

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.

WZT 20 ÷ 100 kW

WZT

Description

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).

Versions
