Internal or external insulation using nitrile rubber helps minimize thermal loss and condensation—boosting HVAC efficiency and reducing energy bills.
Built with precision according to SMACNA standards, our ducts maintain high pressure class ratings and sealing classes (A, B, C) up to 2000 Pa.
Modular, prefabricated duct sections with TDF/TDC or angle flanges simplify on-site assembly, saving time and labor costs.
CNC-fabricated ducts tailored to project blueprints eliminate on-site modifications, delivering precision fit and fast commissioning.
Engineered for Every Space:
At ZECO, we understand that every project has its own space constraints and performance requirements. That’s why we offer three precision-crafted types of air distribution ducts: Rectangular, Oval, and Round –each designed to optimize airflow, maximize efficiency, and adapt to unique architectural and operational demands. Whether you’re working with tight ceiling spaces, exposed duct layouts, or high-performance systems, ZECO has the perfect ducting solution tailored for you.
Choose the Right Duct for Your HVAC Needs
Rectangular Duct
ZECO rectangular ducts are ideal for installations with limited vertical space. Their flat design allows for easy integration into ceiling voids and tight spaces, making them perfect for commercial and industrial buildings where space efficiency is critical.
Round Duct
ZECO round ducts ensure superior airflow and reduced air resistance, making them highly efficient for ventilation systems. Easy to install and cost-effective, they are a preferred choice for many HVAC applications.
Oval Duct
Combining the low-profile advantage of rectangular ducts with the airflow efficiency of round ducts, ZECO oval ducts offer both aesthetics and performance. They are perfect for exposed installations and environments that require both form and function.
