Meticulous Engineering - Exactly When You Need It



World class design, machining and assembly of precision and complex products


DEP specialises in the maintenance, overhauls and servicing of Gas Turbines and their associated equipment.

Turbine Control Systems

DEP provides a complete automation control solution for industrial gas turbines, station controls and safety systems. Providing complete SCADA, PLC & DCS as well as Fault Tolerant systems, DEP is at the very forefront of machinery control and monitoring technology.

Our turbine control systems provide the basic engine sequencing and closed loop governor control of gas turbines and can include; HMI systems, plant control systems such as Station Control and Anti-surge control systems for turbo-compressor plant, as well as synchronization and load control for power generation equipment.

Older turbine control systems will eventually reach a point where they are no longer reliable or supportable and the operator may not have the luxury of installing new control cabinets. The operator may instead require a new turbine control system to fit within the existing footprint. 

DEP Systems are specialists at developing retrofit solutions for existing turbine installations, enhancing the control and monitoring available, and providing pathways for ongoing supportability with readily available software and hardware.  DEP enables clients to take advantage of the enhanced capabilities of the latest controller hardware, SCADA systems and DCS integration, whilst maintaining the existing mechanical systems, field instrumentation and overall layout.

DEP provides a complete integration service for turbine control projects, bringing together new or existing turbines with bespoke controls, complete with gas generator and driven load controls.  Whether your application is; power generation, pumping, or compression, we can provide a single procurement interface and deliver the whole solution.
