Direct Replacement Controllers

HPI has engineered direct replacement units for aging and obsolete, or unsupported OEM controllers:

These control solutions include precise automatic governing, sequencing and load control, regardless of industry or application. The HPI control systems have been proven to dramatically increase start availability, reliability, and performance when compared to analog-relay or hydro-mechanical systems. They also have extensive diagnostics and communication facilities allowing for easy interface with other systems, including SCADA or DCS. These systems are safe and cost effective, providing a flexible solution to any application.
