LZT – High efficiency air source heat pumps with E.V.I. compressors with Heating Capacities from 10 to 200 kw.

The LZT series of high efficiency heat pumps have 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.a.Air Source Heat Pumps

LZT units are available in 2 pipes, 2+2 pipes and 4 pipes versions.
Some versions can produce domestic hot water, in the P2S version through the activation of an external 3-way-valve and in the P4S version by means of a separate heat exchanger and hydraulic circuit for the domestic hot water.

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 10-12 dB(A) (Optional).
