Yes, it can. If your CSM, RFM, or CSC coilers is up and running, we can retrofit it at our Chicagoland facility with the upgraded electronic components and operating systems including motors, computer drivers, servos and cabling to bring your machine up to current standards—all at 1/3 the cost of a new machine, and with a full 1-year factory warranty.

Our rugged Herdon machines come with a 2-year factory warranty on parts and labor, and at RK Trading, we guarantee that if your machine doesn’t perform as promised, we’ll refund you 100%.
