Design fan coil unit with a minimum depth of 10 cm only and BLDC motor ART-U 1 - 4 kW Design-driven innovation From the extensive experience of Galletti in the development and design of fan coil units, and in confirmation of its continuous search for innovation, has been created ART-U, the result of a perfect combination of performance and design. The goal achieved by this project is absolutely ambitious: a new and unique product, not yet present on the market, which on the one hand is able to meet the increasingly stringent demands for energy efficiency, and, on the other hand, for the first time, reflect the latest trends in furnishings and interior design. With the new ART-U, this goal has been fully achieved, presenting on the market a new concept of hydronic indoor unit, a product that is characterized by its enviable technical performance and at the same time represents a true style shift in a field that has long been dominated by products that are all very similar to each other. ART-U, with its depth down to only 10 cm, and thanks to its unique lines, was designed to be an absolutely all-purpose product, that adapts perfectly to rigorous and essential environments as well as to warmer and more sophisticated spaces. Thanks also to the possibility of customizing the front panel, ART-U meets the demand for ever more personalization of the spaces to be furnished. The achievement of extremely high aesthetic standards has not weakened the usual construction integrity of Galletti products: striving for innovation has in fact also focused on the components and the use of new materials. With ART-U the state of the art has been redefined also in terms of technical performance, thanks to the use of computational fluid dynamics simulations for the optimisation of the heat exchange inside the indoor unit combined with the use of permanent magnet electric motors.

MAIN COMPONENTS Upper grille Consisting of adjustable fins made of anodised aluminium, available in the version for on-board or wall-mounted control. The ABS combs support the grilles and prevent them from being bent, thus always guaranteeing the user’s safety. Conveyors Made of high-density polystyrene. They are designed to optimise the air flow inside the hydronic indoor unit allowing optimal distribution of the air flow in the coil and low noise in every operating mode. Front grille Stabilizes the operation of the tangential fan unit and is equipped with a stainless steel filter. Electric...

AVAILABLE VERSIONS ART-U Grey The front panel made of brushed aluminium, combined with black side panels, was designed to enhance the reduced depth of the fan coil. The product, with simple, clean, and essential lines, fits perfectly in environments whose furnishings follows new trends and where a high level of design is required for each item. ART-U White The neutrality of the white ensures maximum integration with the space in an adaptive context, allowing the fan coil unit to almost disappear into the wall. ART-U it can be customized with different color variations upon request.

COMPUTATIONAL FLUID DYNAMICS SIMULATIONS Hydronic indoor units - ART-U The model Computational Fluid Dynamics (CFD) is a method that uses numerical analysis to solve the problems of fluid dynamics by using computers. For the ART-U project it was considered a computational domain discretized by means of a polyhedral calculation grid (mesh) consisting of 12 million cells. The mesh has a refinement that extends to the entire rotor area to better reproduce the vorticity that is created in that area. Air motion field During the initial phase of development of the ART-U project the calculation...
