How Betec Cad’s Advanced Blade and Seal Construction Improves Energy Efficiency

Betec Cad's Blade Design Boosts Energy Efficiency

Double-Skin, Aerodynamically Optimized Blades Reduced Airflow Resistance: Aerodynamically shaped blades are designed to allow air to flow smoothly over and around them, minimizing turbulence and drag. Less turbulence means the system requires less energy to move air through the damper, reducing fan power consumption. Lower Pressure Drop: Double-skin blades (blades with two layers and possibly… Continue reading How Betec Cad’s Advanced Blade and Seal Construction Improves Energy Efficiency

The Role of Return Air Grilles in Better HVAC Performance

Return Air Grilles

When we think about HVAC systems, we often focus on big parts like air conditioners, heaters, and ductwork. But smaller components play a huge role too, especially the return air grilles. These grilles are critical for the system’s efficiency, indoor air quality, and overall comfort. Without properly functioning return air grilles, even the most expensive… Continue reading The Role of Return Air Grilles in Better HVAC Performance
