TETRIS is the compact version of a spray booth, combining high quality jobs with major energy savings. It addresses the refinishing issues of relatively small objects without having to revert to a standard sized automotive refinishing spray booth. The reduced dimensions result in two advantages: profitability is increased thanks to low energy costs; by leaving the main spray booth free, it can be more efficiently dedicated to objects of larger dimensions, optimising workshop productivity and energy consumption. The savings obtained by using TETRIS allow for a quick return of investment; rapid investment return leads to full convenience and profitability of this new spray booth.
