EPRI BPDU Upgrade, Repair & Replacement Services

JJENCO personnel were responsible for the design and construction of EPRI's Bolted Joint Performance Demonstration Units (BPDU) from their inception in 1995.

EPRI BPDU are larger, heavier, and less fully-functional than are JJENCO FADU, and many are now over two decades old. JJENCO offers BPDU owners a cost-effective upgrade path to convert their existing BPDU to a new JJENCO FADU. However, for those who wish to continue to use their BPDU, JJENCO also provides complete repair and refurbishment services, as well as an assortment of the custom spare parts unique to the BPDU design.
