Key Features & Technical Advantages

This monoblock forced draught gas burner features a fully automatic two-stage progressive operation, housed in a compact, user-friendly structure designed to maximize operational lifespan and simplify daily maintenance.

Optimized Air Intake System: Carefully equipped with premium soundproofing material to significantly reduce operational noise, ensuring a quieter industrial environment.
High-Performance Fan: Utilizes a straight blade design that substantially improves airflow efficiency and reduces electrical consumption.
Precise Airflow Regulation: Incorporates an advanced air damper and butterfly valve system to control air and fuel flow precisely on both the first and second stages. This is driven by a reliable servomotor featuring a variable cam for exact adjustments and optimal air-fuel ratios.
Robust Starting Motor: Operates efficiently at 2800 rpm. It is available in versatile power configurations, including single-phase 220-230V/50-60Hz or three-phase 380-400V/50-60Hz, catering to diverse facility requirements.
Durable Combustion Head: Expertly constructed with a corrosion-resistant and high-temperature-resistant stainless steel end cone. It comes fully fitted with ignition electrodes, an ionization probe, a precision gas distributor, and a flame stability disk to guarantee stable, reliable, and clean combustion.
Patented Housing Cooling System (HCS): A unique thermal management solution featuring high thermal insulation and continuous air circulation. It actively cools the burner housing, safeguarding sensitive electrical components from heat degradation and extending the equipment's service life.
Reliable Safety Devices: Integrates a highly sensitive minimum air pressure switch that immediately stops the burner operation if insufficient airflow is detected at the combustion head, preventing hazardous conditions.
Microprocessor Safety Control Box: Delivers comprehensive operational monitoring, real-time status updates, and precise fault diagnosis, empowering technicians to resolve issues swiftly.
External Electrical Connections: Designed with accessible plug-and-socket connections located on the exterior of the cover, drastically reducing the time required for installation, wiring, and routine maintenance.
Intuitive Operational Switches: Includes straightforward controls for Burner ON/OFF and manual 1st-2nd stage operation, providing operators with direct control when needed.
Flame Observation Window: Features a strategically placed viewing port that allows for quick, safe visual inspection of the flame status without dismantling the unit.
Installation Convenience: Thoughtfully equipped with built-in slide bars, making the processes of initial installation, inspection, and component maintenance significantly easier and safer.
Electromagnetic Interference (EMI) Protection Filter: Ensures stable and uninterrupted electrical operation by shielding the control systems from external electrical noise commonly found in industrial plants.
High Protection Rating: Certified with an IP40 protection rating, making the burner highly resilient and suitable for rigorous industrial environments.
