Versatile air tube heat exchangers by Purple Heat Exchangers. Smooth and twisted tube options for efficient, low-maintenance industrial heat recovery.
The Air Tube Heat Exchanger range from Purple Heat Exchangers includes both smooth tube and twisted tube configurations, designed for efficient air preheating and heat recovery in industrial environments. These systems are engineered to handle a wide range of operating conditions, including high dust concentrations, corrosive airflows, and demanding thermal loads. Both designs offer durable construction, stable thermal performance, and reduced maintenance requirements, making them well-suited for use in sectors such as petrochemical, metallurgy, power generation, and environmental protection.
Features
- High heat transfer efficiency in both smooth and twisted configurations
- Compact, sealed designs with minimal tube wear and long operational lifespan
- Twisted tubes enhance turbulence and resist fouling, ideal for high-dust environments
- Smooth tubes offer a simple, reliable option for stable air-side performance
- All units manufactured to handle elevated temperature and corrosive airflows
- Suitable for both continuous and batch processes across multiple industries
Design Options
Smooth Tube
Smooth tube air heat exchangers are constructed using parallel staggered steel tubes welded to tube plates, forming a cubic box with a consistent heating surface. This configuration is widely used for air preheating in systems where minimal pressure drop, ease of installation, and low maintenance are priorities.
Twisted Tube
Twisted tube variants utilise a three-dimensional, variable-diameter structure that increases surface turbulence and promotes extended contact between air and tube surfaces. This improves heat transfer rates and reduces fouling, while the baffle-free, self-supporting design eliminates common structural weak points.
Applications
- Industrial waste heat recovery
- Air preheating in combustion systems
- Energy efficiency improvements in petrochemical and metallurgical plants
- HVAC and air handling units in high-dust, high-load environments
- Thermal management in electric power and environmental protection systems
