MI-SWACO CD-250 centrifuge is designed for the purpose to solve a problem that there is no proper model centrifuge for small drilling process application with a compact dimension, for example, HDD, diamond core drilling for mining. It should meet 3 important points: 1 high separation efficiency, 2 tight space, 3 economic solution. GNLW220 centrifuge is designed for the similar purpose.

Both of them are very compact footprint units, and designed with easy maintenance in the field and continues operation in harsh environment. Compared with CD-250 centrifuge, GNLW220 is more competitive in price and delivery time, they are function equivalent.
Swaco CD-250 has been tested in Berra, Italy , and the testing result is excellent, all actual parameter exceeds design parameters. It has been widely used in Chile for mining diamond core drilling and other small drilling process. If you want to find function and parameter equivalent centrifuge with CD-250, GNLW220 will be your best choice.
