In today’s rapidly evolving energy landscape, the demand for clean, efficient, and autonomous power solutions has never been greater. Traditional diesel and gas generators, while reliable, often come with drawbacks such as noise, emissions, and maintenance costs.
RIGID introduces a breakthrough alternative — the Stirling Generator RS1000, a compact, high-efficiency, and long-life power generator based on Free-Piston Stirling Engine (FPSE) technology. Designed for off-grid, industrial, and critical infrastructure applications, the RS1000 represents a new era of sustainable energy generation.
What Is the Stirling Engine?
The Science Behind RS1000
At the heart of the RS1000 lies the Free-Piston Stirling Engine, a closed-cycle regenerative heat engine that converts external heat into electricity.
Unlike traditional internal combustion engines, the Stirling Engine operates using external combustion, meaning it can utilize almost any heat source – from gas and biogas to solar and biomass.
The Working Principle (Four-Step Cycle)
-
Expansion (Heating Stage)
External heat causes the working gas (helium) inside the sealed cylinder to expand. This expansion pushes the power piston, creating mechanical energy. -
Displacer Movement
The displacer piston shifts the gas toward the cooler side of the cylinder, preparing it for the cooling phase. -
Compression (Cooling Stage)
As the gas cools, it contracts, generating reverse pressure that pushes the power piston back, completing a mechanical cycle. -
Repeat & Continuous Cycle
The process repeats continuously. A linear alternator then converts the piston’s oscillation into electricity.
The result is a maintenance-free, low-vibration, high-efficiency power system capable of continuous, clean operation for years.
