Automatic HVAC pipe production lines

TTEngineering designs and manufactures advanced automatic pipe production lines specifically tailored for the HVAC sector and related applications, including ventilation, air conditioning, and chimney systems. These systems enable manufacturers to produce high-quality round and custom-shaped pipes through a fully automated process, ensuring excellent joint integrity and consistent dimensional accuracy.

By integrating precise bending, advanced clamping technologies, and high-performance laser welding, these lines are engineered to meet the stringent quality standards required by modern HVAC installations — ensuring optimal airflow, long-term durability, and easy on-site assembly.

CSU-S

The CSU-S line delivers fully automatic bending through the FlexFormer® TT2 system and features a flexible clamping bench for laser welding. It is available in two variants to meet different production requirements:

1. Diameter range: Ø 76–400 mm, maximum length: 1,000 mm
2. Diameter range: Ø 76–400 mm, maximum length: 1,250 mm

Thanks to its compact footprint and high configurability, the CSU-S is an excellent solution for manufacturers seeking reliable, repeatable production of medium-sized HVAC pipes, while ensuring superior joint quality and consistent geometric accuracy.

CSU

The CSU line also integrates fully automatic bending, using the FlexFormer® TT2 or TT3 systems, combined with a flexible clamping bench for laser welding. Designed to accommodate larger diameters and a broader range of configurations, the CSU is available in three variants:

1. Diameter range: Ø 80–500 mm, maximum length: 1,000 mm
2. Diameter range: Ø 80–500 mm, maximum length: 1,250 mm
3. Diameter range: Ø 80–500 mm, maximum length: 1,500 mm

This model is ideal for manufacturers producing a wide variety of medium- to large-sized HVAC pipes, enabling high-volume output while ensuring precise weld quality and dimensional consistency.

With TTEngineering’s complete portfolio of automatic HVAC pipe production lines, manufacturers can achieve reliable, accurate, and highly efficient production for air conditioning, ventilation, and chimney systems. Each line is engineered to maximize productivity, minimize manual handling, and deliver top-quality pipes that meet the demands of modern HVAC and metalworking installations.

CSU-XL for heavy-duty applications

The CSU-XL is the largest model in TTEngineering’s HVAC pipe production portfolio, specifically designed for heavy-duty applications and the fabrication of large-diameter pipes. It combines fully automatic bending (via FlexFormer® TT2 or TT3) with a robust, high-precision laser welding unit, ensuring top performance under demanding production conditions.

The CSU-XL is available in three variants:

1. Diameter range: Ø 100–770 mm, maximum length: 1,000 mm
2. Diameter range: Ø 100–770 mm, maximum length: 1,250 mm
3. Diameter range: Ø 125–770 mm, maximum length: 1,500 mm

This model is ideal for producing large ventilation ducts and chimney pipes, where structural strength, perfect roundness, and high weld integrity are essential. Its superior capacity and precision enable manufacturers to handle complex HVAC geometries without compromising performance or reliability.

CSU-MS (Multi-Shape)

The CSU-MS is a unique, multi-purpose solution designed for the production of both round pipes and multi-ray shaped pipes. It integrates fully automatic bending using FlexFormer® technology, combined with a high-performance laser welding unit equipped with top-tier laser sources.

The system supports:
- Round pipes from Ø 73 to 400 mm
- Multi-ray profiles with a minimum bending radius of 40 mm
- Maximum pipe length: 1,000 mm
- Wall thicknesses from 0.4 to 1.0 mm

The CSU-MS is ideal for manufacturers requiring maximum design flexibility to produce customized HVAC components, including special connectors, transition pieces, and aesthetic ducting solutions.

All TTEngineering HVAC pipe production lines deliver high-quality weld joints through advanced and precise laser welding, ensuring repeatable and efficient manufacturing processes. These systems are engineered to fully meet the stringent performance and reliability standards of modern HVAC installations.
