Witzenmann is the world's leading manufacturer of flexible and rigid pipework components for classic combustion engines (diesel, gas and dual fuel drives). By continuously developing our products, we help to further reduce CO2 emissions.

Upstream Turbocharger Automotive Components

Upstream of the turbocharger

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

Downstream Turbocharger Automotive Components

Downstream of the turbocharger

Decoupling elements in the exhaust gas range are temperature and corrosion resistant. Depending on the application, they will be used with or without insulation. Their applications lie in thermo-mechanics (decoupling of vibrations and heat expansions), compensating for mounting inaccuracies or as special elements for dampening structure-borne noise/sound.

Products for these applications are:

Decoupling elements
Structure-borne noise/sound decoupling elements
Stripwound hoses
Pipe systems

Fluid Oil systems oil water cooling circuit

Fluid systems

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.

Applications for new energy vehicles

A team of specialized engineers from our prototype production and test departments is developing trend-setting New Mobility product solutions in cooperation with our customers. For example electromobility, hydrogen or fuel cell technology. Here we draw on our many years of experience and knowledge of the market.

Your development partner in every phase

From design and calculation, operational loads determination and prototype verification to lifespan validation and large series production - Witzenmann's engineers contribute the experience and know-how to arrange for projects to be carried out economically and efficiently.
