Mixed-Phase Capability
The boundary-layer architecture is designed to tolerate conditions where vapor and liquid coexist.
Guardian Turbine System
Recover more energy from every thermal process.
The Guardian Turbine System is a compact boundary-layer turbine engineered to convert thermal and kinetic energy from steam and other working fluids into mechanical power across operating conditions that can be difficult for conventional bladed turbines.

The operating challenge
Conventional turbines often require tightly controlled conditions.
Traditional steam turbines are generally designed around dry-vapor operation. Condensation, liquid droplets, fluctuating pressure, and mixed-phase flow can reduce performance, accelerate wear, or require additional equipment to protect the turbine stage.
Phase-Change Sensitivity
Liquid formation within conventional bladed turbines can contribute to erosion and operating risk.
Complex Steam Conditioning
Maintaining tightly controlled pressure, temperature, and dryness can add substantial balance-of-plant complexity.
Limited Fit for Variable Thermal Streams
Waste-to-energy, chemical conversion, and distributed systems may produce working-fluid conditions that vary over time.
Scale and Weight Constraints
Conventional turbine packages may be impractical for modular, mobile, or distributed energy applications.
Tangential inlet
Central exhaust
Closely spaced boundary-layer discs
System architecture
Energy transfer through the boundary layer.
Instead of directing fluid against conventional blades, the Guardian Turbine uses a series of smooth rotating discs. Working fluid enters tangentially, transfers momentum through viscous interaction with the disc surfaces, and spirals inward as energy is extracted.
Disc-Based Rotor Assembly
Closely spaced discs create the surface area required for boundary-layer momentum transfer.
Tangential Fluid Entry
High-energy working fluid is introduced around the turbine perimeter to establish rotational flow across the discs.
Inward Spiral Flow
As energy is transferred, the working fluid moves toward the center and exits through central exhaust ports.
Integrated Power Transmission
The rotating assembly transfers mechanical energy to a generator or other external drive system.
Engineering advantages
Designed for thermal streams that do not always behave perfectly.
The Guardian Turbine System is intended to provide greater operating flexibility across steam, mixed vapor-liquid flow, exhaust gases, refrigerants, and other working-fluid applications subject to system design and material compatibility.
Fewer Delicate Flow Surfaces
Disc-based energy transfer reduces dependence on complex aerodynamic blade geometries.
Compact System Architecture
A smaller, lighter turbine package can support modular and distributed energy applications.
Thermal Flexibility
The system can be configured around a range of pressures, temperatures, and compatible working fluids.
Applications
A core energy-conversion system for multiple thermal processes.
The Guardian Turbine can serve as a standalone energy-recovery component or as part of a broader Guardian system where recoverable heat, steam, or pressurized working fluid is available.
Industrial Waste Heat Recovery
Capture useful mechanical energy from thermal streams that would otherwise be rejected or underutilized.
Steam & Process Systems
Support industrial steam applications where pressure, temperature, and phase conditions may vary.
Solar Thermal Power
Convert stored thermal energy into mechanical power within a dispatchable renewable-energy architecture.
Distributed Energy Systems
Enable compact power conversion in modular, remote, mobile, or site-specific generation systems.
From design to deployment
The turbine must perform as part of a complete system.
Commercial success depends on more than the rotating assembly. Inlet conditions, fluid chemistry, seals, bearings, exhaust handling, condensate management, generator integration, controls, and maintenance strategy must be engineered together.
Working-Fluid Characterization
Evaluate temperature, pressure, phase behavior, contamination, corrosion potential, and flow stability.
Application-Specific Configuration
Match disc spacing, inlet geometry, materials, seals, shaft requirements, and output characteristics to the operating environment.
Integrated Testing
Validate torque, rotational stability, thermal performance, condensate behavior, durability, and energy-conversion efficiency.
Modular Scale-Up
Use repeatable turbine modules to support different power levels and broader system architectures.
