TECHNOLOGY
Innovation. Agility. Performance. These are the words that drive our designs at Signal Power. Our technologies are built to adapt to client needs, site conditions, changing landscapes, and market volatility. From mobile systems that can be deployed anywhere for anything, to prime power for high-tech manufacturing, we create technologies that future-proof our clients' projects.
Our flagship turbine is the result of a proud exclusive partnership with Honeywell to bring the T55 aerospace turbine to new applications outside of aviation, with Signal Power Group as the OEM. Learn more about the T55 turbine's history here.
The SPG4 Combustion Turbine has a solid legacy in demanding military environments. With over 12 million operating hours across six decades, its history of reliability in extreme conditions makes it the perfect workhorse for our wide range of applications. From Combined Heat & Power (CHP) installations that require year-round operation, to temporary projects where time is critical or lives are on the line, durability is key. The SPG4 is built for the endurance that these projects demand.

PATENTED GEARBOX TECHNOLOGY
At the power end of the SPG4 is one of two proprietary gearbox designs, to adapt the SPG4 to either an electrical generator for power applications or to a mechanical drive system, such as in pressure pumping.
Direct Drive
Two-Speed Gearbox with Neutral Capability allows for flexibility in operation. This is truly a revolutionary technology in pressure pumping, as it allows operators to adapt to site conditions as opposed to the limitations of conventional turbine technology in mechanical drive applications.
In-House Turbine Testing
As the energy landscape changes, we are constantly adapting to new and exciting use cases for turbine technology, and the versatility of the SPG4 shines in these unique applications.
Our full-scale turbine testing facility enables us to hit the ground running when we deploy on site by replicating real-world scenarios and eliminating unforeseen variables before we deliver.
Multi-Purpose
From developing next-generation technology to putting our next delivery through the paces, we run a wide variety of activities on site:
-
Standard Factory Acceptance Testing (FAT) on outgoing turbine systems, including electrical generation and direct drive power
-
Live demonstrations for new clients or applications
-
Ongoing research & development initiatives to increase turbine power and efficiency
-
Custom fuel mixtures to replicate real-world scenarios for alternative fuels
-
Control system updates
In-house design and manufacturing of control systems
At the heart of all Signal Power Group's systems is our patented in-house control system, known as the ATDEC. With decades of turbine operation experience within our design team, we understand the need to simplify the operation of complex equipment so our clients can focus on their business. The ATDEC architecture is designed to condense the array of inputs from our equipment into easy-to-understand, useful data.
In addition, several I/O interfaces are reserved for additional custom sensors that can take in external data from upstream or downstream in the process, and control our equipment with a focus on the larger picture. This gives end users the control they actually need, and removes the guesswork from the system.
Safe Operation: Over 100,000+ hours of operation, we have optimized our control systems with the necessary guardrails to prevent misuse, ultimately reducing operating costs and increasing on-site safety.
Data Logging: Our data logging system enables us to remotely evaluate sensor data, for a hands-on approach to predictive maintenance, resulting in minimal downtime. This data is available to end users as well, enabling everyone to collaborate on potential optimizations, upgrade opportunities, and areas to further bulletproof the system.
Internal Redundancy: Each ATDEC is equipped with two ZINQ 7000 processing units for built-in system redundancy, required in military applications and highly applicable in industrial systems.
