Construction / Agricultural machinery

A wide variety of flexible elements, fitted with customer-specific connections, are used before the turbo charger to absorb heat expansions and decouple engine movements and vibrations.
Such as

• Exhaust gas ducts
• Ducts in the manifold area
• Exhaust gas recirculation pipe without microfilter

Pipeline systems for liquid circuits such as water, oil and coolant circuits are mostly semi-flexible bellows/smooth-bore tube solutions or custom-fit curved stainless steel pipelines, precisely tailored to the cramped installations conditions close to the engine. Alongside traditional combustion engines, these air-tight pipe systems are increasingly used in E-mobility or hydrogen applications.

As a supplier to virtually every notable commercial vehicle manufacturer, Witzenmann possesses a vast body of practical knowledge. This serves as the basis for the development of precise special solutions, such as:

• conduits for pneumatic and fluid systems
• pressure pipe sheathing
• exhaust gas consolidation
• pipes for special media such as CO2

Flexible pipe elements are used at the engine to absorb thermal expansion, vibrations and to compensate for installation tolerances.

• expansion elements
• exhaust manifolds
• charge air lines
• oil / exhaust gas re-circulation pipes
