Forney CA-0399 RetroPak with Automatic Controls

Designed and built by Forney, the CA-0399 RetroPak converts your manual machine to an automatic machine.

Forney RetroPak™ is an automatic control system that easily retrofits to most manual testing machines. The CA-0399 series of drive and control packages are specifically designed for testing a variety of materials in compression and flexure on machine frames with larger cylinder diameters. Additional pump flow and reservoir size have been incorporated into the design in anticipation of large hydraulic piston and a variety of accessories. It allows seamless conversion of a manual machine to fully automatic and arrives pre-wired and pre-assembled making installation and connection quick and simple. RetroPak is the easiest way to upgrade a testing machine to fully automatic operation. It’s also the only one that works with ForneyVault.
