Everything Else
Degree Day Pvt. Ltd. is Central India’s largest manufacturer of Pre-Fabricated Ducts, delivering world-class HVAC ducting systems including Rectangular Ducts, Spiral Ducts, Oval Ducts, and Pre-Fab Ducts for a wide range of applications. With over 25 years of excellence in the HVAC industry and ISO 9001:2015 certification, we provide turnkey design and execution services for ventilation, air conditioning, cleanrooms, and industrial cooling systems.
Our Rectangular Ducts are engineered for performance, durability, and precision. Manufactured using top-grade galvanized iron (GI), mild steel (MS), or stainless steel (SS), these ducts are ideal for large commercial complexes, hospitals, cleanrooms, and industrial facilities. Each duct is fabricated using automated CNC plasma cutting and lock-forming technology to ensure dimensional accuracy, leak-tight joints, and superior airflow efficiency.
Spiral Ducts from Degree Day offer a modern and efficient alternative to traditional duct systems. These ducts are lightweight, robust, and aesthetically pleasing—perfect for exposed HVAC installations in offices, malls, airports, and industrial environments. The spiral design minimizes pressure loss, reduces air leakage, and ensures cost-effective performance. Available in various diameters and materials, our spiral ducts comply with SMACNA and ASHRAE standards for energy-efficient ventilation.
For projects with limited space or unique architectural needs, we offer Oval Ducts that combine functionality with space optimization. These ducts provide the aerodynamic benefits of round ducts while maintaining a flat, compact profile ideal for tight ceiling or wall spaces. Each oval duct is precision-formed to deliver high airflow efficiency and reduced noise levels, making them an excellent choice for modern HVAC systems.
As a leader in Pre-Fabricated Duct Manufacturing, Degree Day Pvt. Ltd. has revolutionized the way duct systems are designed and installed. Our state-of-the-art production facility enables off-site duct fabrication with high accuracy, faster turnaround times, and minimized on-site labor. Pre-fab ducts are delivered ready to install, ensuring faster project execution, cleaner installation, and consistent quality control.
Our in-house engineering and design team works closely with architects, consultants, and contractors to ensure every ducting system meets exact project specifications. From design optimization and airflow analysis to fabrication and installation, we deliver complete end-to-end HVAC ducting solutions that stand the test of time.
