Low noise mini cassette
19th January 2016
EUROPE: Hitachi Air Conditioning Europe has introduced what it claims is the lowest noise level mini cassette air conditioner on the market.
The new RCIM FSN4 mini cassette range is also claimed to be the widest on the market, with capacities ranging from 0.6hp to 2.5hp (1.9kW to 8.5kW nominal capacity in VRF system heating mode).
Its 620 x 620mm dimension has been reduced by 80mm compared to the previous model so it can be installed into a 600 x 600mm grid ceiling without needing to cut the grid or interfere with lighting or other ceiling fixtures and fittings.
The unit features newly structured louvres which close when the unit is switched off, giving a discrete profile and avoiding the accumulation of dust. Each louvre can be controlled individually, while the redesigned panel louvres and the shape of air outlets are said to improve the Coanda effect so that cold air follows the ceiling line instead of falling directly towards the floor, eliminating draughts.
The improved 3D twisted blade of the turbo-fan and the air outlet is said to achieve good low noise performance – the 0.6hp to 1hp units’ noise pressure levels are only 24.5dB(A).
An optional motion sensor adjusts temperature and airflow automatically according to activity.
Using Hitachi’s System Free concept, the new range of RCIM FSN4 indoor units can be combined with all Hitachi splits and VRF outdoor units.
