The GSC400 has been in production for approximately 13 years, and has been great product to this day. However, because of advances in technology and newer electronic engines, Dynagen has designed the new tough series TG410 as the recommended replacement.  Technical help, if needed, is available for the transition to this new design.  As the GSC400 is now no longer in production, we are unable to purchase them from Dynagen anymore. 

Click here to view a comparison of the differences / similarities between the TG410 and the GSC400.  Note:  While the GSC400 is no longer recommended for new projects or designs, it is easier to replace an existing unit with a new GSC400, rather than installing a TG410.
