Cassette fan coils with BLDC motor IWC i  3 - 5 kW The new hydronic cassette unit with modulating fan control for a perfect mix of comfort and precision In the new water cassette with inverter technology, Galletti combines ten years of know-how in comfort air conditioning with the technology of brushless motors, offering a series of adjustment logics capable of adapting the product to every need. The modulating control of the fan speed ensures a continuous adaptation of the delivered power to the thermal load without disturbing the user with abrupt changes in the noise emitted. The extraordinary technology of the permanent magnet BLDC motors offers an additional advantage over the solution with asynchronous motors, reducing electricity consumption by up to 75 %. The adjustment logic offers the user a control based not only on temperature but also on the humidity present in the room, with an intelligent analysis of the temperature actually perceived by the user. Galletti responds to growing demands for precision, quiet operation, energy savings and aesthetic value with IWCi, a unit with advanced technological features developed with the traditional care that distinguishes the company’s products. The unit can be controlled by means of the remote control, optionally connected with the kit provided. False ceiling mounting ERGO Supervision PLUS Permanent magnet BLDC motor for precise, continuous control Electrical input reduced by more than one half compared to the ON/OFF version Sturdy structure and pleasing design Temperature reading via the remote control Control of perceived temperature Serial communication networks AVAILABLE VERSIONS IWCi IWCi DF Unit with 1 heat exchanger Unit with 2 heat exchangers
