Powering Independence with Advanced Vertical-Axis Wind Turbines

The WRTB is a next-generation vertical-axis wind turbine (VAWT) engineered for distributed energy, urban environments, and the world's harshest climates.

Our competitive edge is born from a groundbreaking, omnidirectional counter-rotating design. It captures more energy from variable winds while being built dramatically tougher. This inherent simplicity translates to superior durability, safety, and truly autonomous operation—eliminating the constant protection and intervention required by traditional propeller turbines. We don't just compete on efficiency; we dominate on reliability.

Proven Technology, Built to Last
Our flagship WRTB-2M turbines are 2.5 kW and 5 kW models and 10 kW solutions. Originally developed by scientists Sergey Bolotov and Academician Albert Bolotov (Patent No. 20572) and recognized globally at exhibitions like EXPO 2017 Astana, this technology has been proudly manufactured in-house since the 1990s.

These turbines are trusted in extreme environments worldwide—from Arctic cold to desert heat and high-altitude mountains. They have proven their unmatched resilience by withstanding hurricane-force winds in excess of 44 m/s.

Since 2010, we have deployed over 390 turbines, continuously refining our technology based on real-world performance.

For Decision-Makers: Evaluating a Fundamental Shift in Wind Technology

Selecting a wind power solution for critical infrastructure involves more than comparing energy outputs. It represents a strategic choice between two divergent engineering philosophies: the conventional Horizontal-Axis Wind Turbine (HAWT) and the purpose-built, Vertical-Axis (VAWT) WRTB system. Understanding this distinction is essential for achieving long-term resilience and autonomy, not merely short-term power generation.

The Core Difference: Design Philosophy & Application

The Conventional HAWT: An Add-On Generator
Traditional HAWTs are designed as standalone generators. Their efficiency depends on clean, laminar wind flow, making them susceptible to performance degradation in the turbulent conditions typical around buildings or in complex terrain. They require a separate, dedicated foundation and significant clearance space. Their complex mechanics—including yaw systems and pitch controls—are vulnerable in extreme weather, often necessitating preemptive shutdowns during high winds. While the initial capital cost may be lower, this can be offset by higher long-term maintenance, operational downtime, and a shorter lifespan in harsh environments.

The WRTB VAWT: An Integrated Structural Solution
The WRTB is engineered from the ground up as a resilient, integrated asset. Its core advantage is exceptional performance in turbulent and variable wind flows. The omnidirectional design captures energy from any direction without reorientation, making it ideal for mounting on existing infrastructure like lattice towers. It is not an add-on; it is built directly into the structural latticework, creating a unified, space-efficient, and coherent system.

Engineered for extreme environments, it operates reliably from -50°C to +50°C and is proven to withstand hurricane-force winds exceeding 50 m/s without shutdown. With simpler mechanics and no yaw system, it is designed for over 20 years of reliable, low-maintenance operation. This results in a significantly lower total cost of ownership, especially for remote or challenging sites.

The Strategic Decision

The critical question shifts from “which turbine is better?” to “which solution is engineered for my specific operational reality?”

Choose a conventional HAWT if you have an open, unobstructed site where maximizing ideal-condition output is the primary goal, and resilience is a secondary concern.

Choose the WRTB VAWT when your priority is unbreakable reliability for critical systems in remote, harsh, or complex environments. It is the definitive solution for minimizing operational interventions, eliminating fuel logistics, and achieving true long-term energy independence.

In essence, the WRTB represents a fundamental evolution in infrastructure power—from a vulnerable add-on generator to a self-powered, resilient structural component.

We welcome the opportunity to provide a detailed, data-driven analysis tailored to your specific site parameters and performance requirements.

Manufacturing

Vertical Integration: Our Complete In-House Advantage

From initial concept to final installation, we maintain complete vertical integration over our technology. We operate our own manufacturing facility and design bureau, where we engineer and produce the core components of the WRTB system: the turbine itself, its proprietary synchronous generators, and the intelligent control systems.

This end-to-end control is a fundamental strategic advantage. It allows us to ensure unparalleled quality at every stage, optimize the entire system for peak performance and durability, and rapidly customize solutions for specific client needs. By manufacturing the critical aggregates—the generator and controller—in-house, we guarantee perfect compatibility and reliability, eliminating the performance risks that come with outsourced, third-party components. Our process delivers not just a turbine, but a fully harmonized and robust wind power system.
