Mitsubishi Electric’s M Series MSZ-LN wall mounted air conditioning units have just been awarded the Noise Abatement Society’s Quiet Mark for their almost silent performance.

The MSZ-LN is the first in the company’s comprehensive range of units using the new R32 refrigerant – which has a low global warming potential (GWP). The streamlined design of the units complements the advanced and comprehensive range of features to make stylish, energy efficient air conditioning available for all.

Toby Saville, chief technical officer for Quiet Mark, said: “The Quiet Mark has been awarded to the new MSZ-LN range in recognition of Mitsubishi Electric’s continuing acoustic innovation and focus on sound levels.”

“As these new models are able to sense room occupancy and turn on automatically, it is even more important for the unit to be unobtrusive and quietly go about heating or cooling the space without drawing attention to itself. Our assessments have shown the MSZ-LN to be one of the quietest air conditioning units on the market today.”

The MSZ-LN range offers noise levels as low as 19dBA and is available in a choice of four sizes from 2.5kW to 6.1kW, with four distinct indoor wall units.

Graham Temple, marketing manager, said: “We are delighted that the MSZ-LN models join our MSZ-EF Zen units as the only air conditioning systems available with the Quiet Mark. Our engineers have developed seriously powerful and sophisticated models but ensured that noise is simply not an issue.”

In addition to the M Series MSZ-EF and MSZ-LN wall mounted air conditioning units, Mitsubishi Electric range of Ecodan air source heat pumps are also endorsed with the Noise Abatement Society’s Quiet Mark.
