LH and LHE

The measurements were taken with the refrigerant R404A at operating frequency 50 Hz.
The tolerance for all specifications is +/- 2 dB(A).
For the measured quantities and their units: Introduction

LHE condensing units

The indicated averaged sound pressure levels apply to free-field conditions with hemispherical sound propagation at a distance of 10 m and correspond to the calculated sum level from the separately measured individual levels for compressor and fan.

Sound pressure levels for LHE condensing units according to application range (preliminary values).
