Cars of the future

Efficient, clean, and quiet

International limits have been set to reduce pollutant emissions from passenger cars. Currently, the emission directives EURO 6, EURO 7 and the EU Regulation 540/2014 on the “noise level of motor vehicles” apply.

In addition, there is increasing pressure from consumers and politicians to offer new drive technologies such as lithium-ion battery systems, fuel cells or hydrogen engines. In addition, the efficiency of trucks and buses must be increased and cost-effectiveness ensured.

Avoid energy losses directly at the source

Efficient exhaust gas aftertreatment with tmax insulation solutions

Thermal insulation from tmax maintains the necessary process heat within the system (turbocharger, manifold, exhaust tract, DPF, SCR, …), thus making a decisive contribution to more efficient exhaust gas aftertreatment.

The effective prevention of energy loss in the exhaust tract offers the following advantages:

  • Prevention of urea crystallization: Heat retention prevents crystals from forming in the diffuser area and reducing the effectiveness of exhaust gas cleaning.
  • Improved light-off behavior: Optimum temperatures in the exhaust gas aftertreatment system are reached significantly faster, exhaust gas aftertreatment works earlier and better, resulting in better exhaust gas values.

Hydrogen engines: The future has a heat problem, tmax the solution

One of the greatest challenges of our time is the pollution of our environment by greenhouse gases and pollutant emissions. Alternative drive systems, such as forward-looking hybrid and environmentally friendly and quiet electric drives, will become increasingly important in the future, primarily for light commercial vehicles in delivery and distribution traffic.

And tmax is a part of it, with proven excellent results in increasing efficiency.

As the industry leader in smart insulating solutions for the hydrogen market, we increase the efficiency of hydrogen engines, turbochargers and manifolds, including for the automotive sector.

More simulations, fewer prototype cycles, lower costs

Developing new products takes time,
but doesn't have to

Unique in the industry: tmax simulations save you endless loops in the development process.

  • Find thermal weak points
  • Vibration simulation for predicting the behavior of a virtual component
  • Simulation for the evaluation of concepts and designs

This way we can identify and eliminate weak points and shorten development times and reduce unforeseen costs, even before a prototype is produced.

We have something against water

The first high-temperature insulation that also protects against water

In wet weather or during engine washing, insulation fibers can easily become saturated with water. The result is a delayed light-off behavior, as the system loses valuable heat as the fiber dries. In this phase, consumption and emissions of passenger cars are particularly high. In addition, the durability of the insulation deteriorates because salt and dirt particles penetrate the fiber along with the water and are deposited there after evaporation.

  • Compliance with emission standards
  • Effective reduction of consumption
  • Easy assembly and disassembly

tmax-DryTec is applicable to all tmax fibers.
