VEPKAR
Ventilation & Exhaust Powered Kinetic Airflow Recovery Generator
VEPKAR is an indoor airflow energy recovery system designed to capture kinetic energy from airflow already present in HVAC systems, ventilation ducts, and exhaust systems.
Core Concept
VEPKAR operates inside buildings, recovering kinetic energy from airflow that is already being circulated by HVAC, ventilation, and exhaust systems. Every building with these systems already moves substantial volumes of air—VEPKAR captures energy from this existing flow without requiring outdoor conditions.
This approach enables consistent year-round operation independent of weather conditions, and generates power at the point of consumption within building systems.
Key Characteristics
VEPKAR is designed for practical deployment in real-world infrastructure.
Inline Installation
Installs directly within existing ductwork without requiring system redesign. Retrofit-friendly design enables deployment in both new construction and existing buildings.
Safe Airflow Pressure
Engineered to maintain safe airflow pressure and volume. Does not obstruct ventilation or compromise HVAC system performance.
Modular & Scalable
Deploy single units for small-scale generation or multiple units across large facilities. Modular design enables customized configurations based on airflow capacity.
Continuous Operation
Generates electricity whenever air flows through the system during normal HVAC operation. Requires minimal maintenance and monitoring.
Consistent Generation
Operates indoors within building systems, enabling consistent generation during normal HVAC operation regardless of outdoor weather conditions.
Modular Architecture
Designed as a standalone system or as part of integrated energy recovery solutions. Can be deployed independently or combined with complementary technologies.
Application Environments
VEPKAR is suitable for any environment with existing airflow infrastructure.
HVAC Systems
Commercial and institutional HVAC systems circulate air for heating, cooling, and climate control. VEPKAR recovers energy from this airflow during normal operation.
Ventilation Ducts
Building ventilation systems exchange indoor and outdoor air for air quality management. VEPKAR integrates into these ducts to generate power during normal ventilation operation.
Exhaust Systems
Industrial facilities, commercial kitchens, laboratories, and manufacturing plants use exhaust systems to remove air. VEPKAR recovers energy from this outbound airflow.
Technical Approach
Energy Recovery Principle
VEPKAR uses turbine technology optimized for indoor airflow velocities and volumes. The system converts kinetic energy from moving air into rotational mechanical energy, which drives an integrated generator to produce electricity.
Safety & Compliance
Designed to maintain safe airflow pressure throughout the duct system. Does not create backpressure that would compromise ventilation effectiveness or HVAC performance. Engineering prioritizes building safety codes and HVAC standards.
Installation & Maintenance
Retrofit installation integrates with standard duct dimensions and connection protocols. Minimal maintenance requirements due to durable mechanical design and continuous operation. Serviceable components enable long operational lifespan.
Standalone Energy Recovery Solution
VEPKAR is a complete, standalone energy recovery system designed for immediate deployment in existing HVAC infrastructure.
As a retrofit-ready system, VEPKAR enables building owners and facility managers to recover energy from existing ventilation infrastructure without requiring new external systems, major modifications, or specialized infrastructure investments.
