The basis for the development of a new series of popular models were the cassette fan coil 42GW. Major improvements have been aimed at reducing operating noise: the new version is fixed below the noise level by 3-6 dB with a standard size 10 and then into a number of sizes. Updated drain pan made of special material, also contributed to reducing the noise level. Modified cassette fan coil is more convenient to install: the control unit is installed outside, and valves are mounted in an isolated box directly.
