ytvà DIUSP9V8UDPIà The new plug-in family for refrigeration is made up of a new series of microprocessor-based electronic controls with LED display, designed for the management of display case and showcase refrigeration units. A range of models is available, providing the best solution for all applications, at the most competitive price. The plug-in family builds on the experience and success of the previous product ranges, such as the IR32 and IR32E, with the aim of offering an increasingly simple and economical product, without relinquishing on the performance required by the refrigeration manufacturer.
