The design procedures are optimized to be as lean as possible; the execution of the projects, taking place in a very short time, allow a very quick answer on required quotation. Specific software for calculating the "heat exchange", allowing the execution of dimensioning of both radiators and exchangers, generate a series of proposals that can guide the customer on a product choice as final as possible, realizing in just a few working days the production of samples, prototypes or pre-series.
