Quality repairs

Our component remanufacturing process combined with strict, comprehensive in-house testing in a simulated environment has resulted in a return rate of less than 1% on all parts that we have remanufactured. This means that your replacement control cards, IO packs, and other components will function like new, all without performing an expensive upgrade or purchasing new parts with long lead times and high costs.

Repair locations

We provide repair services globally from our service centers located in the United States, Middle East (UAE), and India.
