Air Heaters
Nao Inc's air heaters provide direct-fired heating solutions for industrial processes like catalytic cracking and food drying. Designed with UL-listed control systems and high-efficiency burners, they ensure precise temperature control using oil, gas, or combination fuels. Customizable insulation and refractory materials extend operational life while minimizing maintenance.
Flame Arrestors
Custom-engineered flame arrestors protect vessels and pipelines from explosive gas mixtures. Available in vertical/horizontal configurations and corrosion-resistant alloys, they absorb flame heat to prevent ignition. Critical for oil, gas, and chemical industries, these systems ensure compliance with safety regulations.
Burners
Nao Inc manufactures durable burners for industrial applications, including low-NOx and ultra-low-NOx models. Supporting oil, gas, or combination fuels, they feature noise reduction and fuel efficiency. Retrofitting services extend the life of older units while meeting modern emissions standards.
Control Panels
UL-listed industrial control panels ensure safe, compliant operations. Designed to UL508A standards, they integrate burner management systems and flame control components. Regular UL audits verify adherence to electrical safety and manufacturing protocols.
Flares
Engineered flares for offshore/onshore applications include enclosed, steam-assisted, and staged systems. Designed to ISO-9001 standards, they achieve 99.99% thermal oxidation efficiency while minimizing smoke and emissions for environmental compliance.
