Dorin Range CD400 - New Models

With the aim of a continuous product improvement, Officine Mario Dorin S.p.A. informs its business partners of the following changes that will be introduced in the CD400 Range. Through the use of the most modern fluid-dynamic calculation tools, it was possible to implement an innovative gas stream inside the crankcase, as well as new bore and stroke ratios, which assure: - Extreme decrease in oil carry over - Excellent pressure pulses decrease in the discharge pipes - Astonishing optimization at variable frequency operation These modifications apply to larger 4-cylinder models, 24.3 m³/h and above, while CD3000H and smaller displacement models remain unchanged. It is also introduced a change of nomenclature for the involved models as well as a negligible displacement variation, as shown in the below table.
