Thermal & Tubular

Tight spaces, high pressures, extreme temperatures: the demands of engine and exhaust systems found in modern vehicles call for ingenious solutions; a combination of first-class engineering and metal-processing competence.

Thermal & Tubular

Excellence in Engineering Solutions

The demands on the engine and exhaust systems of modern vehicles require ingenious solutions together with first-class engineering and metalworking expertise.

We are a global leader in the production of fuel rails, lines for high-pressure injection systems, and exhaust gas recirculation systems. But that’s not all – we also supply exhaust manifolds worldwide, both as assembled units and as components. Plus, we offer innovative solutions for waste heat recovery in combustion engines, as well as for hybrid and electric vehicles.

Our development and production expertise, combined with our focus on technologies for reducing CO² and pollutant emissions, make us your ideal development partner for modern mobility worldwide.

MOUNTING BRACKETS

Simple. Think outside the box.

High-pressure fuel lines have very complex shapes, which need to be formed, bracketed and brazed. Instead of following convention, at BENTELER, we pre-assemble and braze the brackets, then ends are formed before the tube is bent to its finale shape. That way, we assure the highest level of precision for our customers.

Product families

Battery Cooling Plate

With our innovative and patented Press Brazing process, we produce battery cooling plates that combine reduced wall thickness with optimized strength. In addition to weight reduction, our Press Brazing process uses 100% green electricity.

After-Treatment Systems

AFTER-TREATMENT SYSTEMS

Our exhaust gas cleaning systems are optimized for installation space and performance to allow the largest possible catalytic converters to be fitted in narrow engine installation spaces. They are further optimized for flow and temperature, ensuring efficient conversion of pollutants across the entire area of the convertor and to increase the service life of the components.

Air Gap Insulated Turbine Housings

AIR GAP INSULATED TURBINE HOUSINGS

Our air gap insulation reduces thermal losses compared with cast iron construction for better efficiency and start-up behavior. This leads to up to 38ºC higher catalyst inlet temperatures, which leads to emission reduction. Plus, reduced heat radiation allows a reduction in weight, complexity, and thereby cost of the heat shield.

Dual-Wall Exhaust Manifolds

DUAL-WALL EXHAUST MANIFOLDS

Available as air gap or fiber mat insulation offering lower thermal losses than cast iron construction for better efficiency and start-up performance. This leads to up to 38ºC higher catalyst inlet temperatures, which leads to emission reduction. Plus, reduced heat radiation allows a major reduction in heat shield weight.

Gasoline Particulate Filters

BENTELER offers extensive manufacturing competence across the globe in high-precision integration of precious metal-coated ceramic or metal catalytic converters. Ideal for installation in confined spaces, our filters are optimized for flow to minimize pressure losses, thereby maximizing filter utilization.

Air-Water-Oil

BENTELER supplies a range of steel and stainless steel tubes for air, water and oil systems in engine applications. These draw on our metal processing expertise and feature complex bending and forging processes, including tube assembly, often with hydrogen furnace brazing with copper or nickel solder.

Fuel Rail Assemblies

We are a leading supplier of brazed stainless steel high pressure fuel rail assemblies, with integrated cast, forged and deep-drawn components. We offer global manufacturing and full in-house product and process development capabilities. We fulfil the highest standards with, for example, fully automated injector and sealing package assembly in clean room conditions.

Exhaust Gas Recirculation

BENTELER is one of the world’s leading suppliers of exhaust gas recirculation systems. From concept to series production, we are a full-service provider. Our products feature high-performance cooling with stainless steel construction, optimized internal geometry for maximum heat transfer and high thermal durability for high-performance applications.

Low and High Pressure Fuel Lines

Over seven million fuel distributor rails produced globally per annum! That makes us market leaders in high pressure manifolds. Our stainless steel solutions feature complex bending and direct upset forging of the ball bushings. Our forged fuel distributor rails allow higher injection pressures compared to conventional brazed solutions, thereby reducing pollutant emissions.

Forged And Machined Stainless Steel Manifold Rails

Our stainless steel injection / manifold rails are suitable for injection pressures in excess of 350 bar. With our unique fully-automated machining concept, all machining operations are completed in a single clamping. We also offer fully automated fuel module assembly for piezo injectors with a complex sealing package.
