Versatile air tube heat exchangers by Purple Heat Exchangers. Smooth and twisted tube options for efficient, low-maintenance industrial heat recovery.
Finned Tube Heat Exchangers from Purple Heat Exchangers are built for efficient air heating and cooling across a range of industrial and HVAC applications. By increasing the surface area available for heat exchange, finned tubes offer superior thermal transfer performance, particularly where space is limited or air flow rates are high. These units operate by drawing air across finned surfaces, which may be spiral-wound, extruded, or bonded using advanced welding techniques. With multiple construction options available, Purple Heat Exchangers ensures durability, compactness, and long service life under both high- and low-temperature conditions.
Features
- Multiple fin and bonding options for different performance and budget requirements
- Proven resistance to corrosion, mechanical wear, and temperature extremes
- Compact and scalable designs suitable for both small units and large industrial systems
- Wide compatibility with air preheating, dehumidification, and waste heat recovery setups
Design Variants
1. Spiral Wound Type
Spiral fins are wound tightly around the core tube, delivering high surface contact in a compact, aesthetically clean unit.
Features
Compact structure, easy to install, low maintenance, and long operational lifespan
Material options include carbon steel, stainless steel, and copper
2. Extruded Type
Fin and tube are bonded as a single structure, improving heat resistance and mechanical integrity over extended use.
Features
Strong resistance to thermal stress and deformation
Small thermal resistance and durable heat transfer performance
Available in carbon steel with aluminium fin, stainless steel tube with aluminium fin, or copper tube with aluminium fin
3. String Type
Fin tube with mechanically expanded bonding between copper/aluminium tubes and circular corrugated fins to destroy air boundary layers and improve turbulence.
Features
Optimised fin spacing and tube layout for low air resistance
High transfer efficiency in compact, lightweight units
Used in air handling units and air processing modules
Applications
Air conditioning, dehumidification, cooling, heating, and integration into packaged air units
4. High Frequency Welding Type
A steel sheet is wrapped around the base tube and welded in place using high-frequency techniques to ensure strength, vibration resistance, and durability across a wide thermal range.
Features
High performance under pressure and thermal shock
Excellent joint integrity, long service life, and wide adaptability
Applications
Petrochemical and power generation, boiler economisers, fin-type preheaters, and other heavy-duty thermal environments
