HTS Hauck – NovaStar NS – Ultra Low NOx Rotary Dryer Burner

Overview

The Hauck NovaStar NS Series is an ultra low NOx gas burner engineered specifically for aggregate and asphalt rotary drying applications. Utilizing patented lean burn premix combustion technology, the NovaStar delivers ultra low nitrogen oxide (NOx) emissions on natural gas and vaporized propane without the added cost or complexity of flue gas recirculation (FGR) or water injection systems. The burner produces a short, compact, high-intensity flame suitable for all drum sizes and types, completing combustion within a short zone to minimize flame quenching from process materials.

Available in four model sizes — NS-75, NS-100, NS-125, and NS-150 — the NovaStar is designed for ease of installation and maintenance with a modular, sealed-in construction. Precise airflow control via variable frequency drive (VFD) and compatibility with Hauck BCS PLC-based control panels make the NovaStar a complete, integrated solution for stationary and portable asphalt plant operations.
