RANGE CD400 - NEW MODELS

With a view to a continuous refinement of its products, Officine Mario Dorin S.p.A. has made some changes to the range of CO2 - CD400 compressors.

Using the most modern fluid-dynamic calculation tools, it was possible to optimize the internal flow of the compressor, producing an extreme reduction in the drag of the oil from the compressor to the system.

The new "superquadro" or "short stroke" bore-type ratio has been studied for the use of drivers with a wide range of frequencies, providing an excellent optimization of variable frequency functions.

Both solutions have also made possible a further reduction of pressure pulsations on the discharge line.

The changes made apply to the "top of the range" models of the CD400 Series with displacements of 24.3 m3/h and more, as shown in the table below.

The production of the new models will start from March 2018 and will initially support the current models.
