Key Benefits of Our Thermal Insulation:

• Best-in-class heat retention and thermal efficiency
• Safe reduction of external surface temperatures
• Prolonged component lifetime
• Minimized risk of leakage
• Insulation of any system component
• High-temperature resistance – up to 1,100°C
• Protection against environmental exposure and corrosion
• Flexible insulation thickness options from 2 mm to 30 mm

Enhanced Thermal Management:

Engine component insulation is critical for the thermal management of exhaust systems. Insulating key parts such as the exhaust manifold, turbocharger, and even clamps ensures faster catalyst heat-up, leading to lower emissions without increasing fuel consumption, adding weight, or complicating the system architecture.

Discover how Dinex’s DLTD solutions deliver superior decoupling, durability, and thermal management — even in the harshest conditions.

Dinex’s Leak-Tight Decoupling Elements (DLTD) combine superior decoupling performance with 100% leak-tightness and integrated thermal insulation — setting a new standard for exhaust system reliability.

Designed to accommodate movements in all directions, including torsional motion, the DLTD ensures trouble-free operation even when placed upstream of AdBlue^® injection.
Its robust construction allows installation in any location within the exhaust system, delivering consistent performance even in the harshest operating environments.

Proven Performance:

• Deposition Rate [%]: 0.3% (vs. competing technologies: 1.4%)
  Thanks to the innovative inner-layer profile design, Dinex DLTD features a very low urea deposition rate, ensuring cleaner system operation and reduced maintenance needs.
• Surface Temperature [°C]: <200°C
• Temperature Drop [%]: 60% less compared to conventional designs
  The integrated insulation layer preserves more heat within the exhaust stream, promoting safer external surface temperatures, enabling more compact system designs, and improving emission control efficiency.

Additional Advantages:

• Minimal risk of material fatigue failures
• Greater resistance to external mechanical damage
• Optimized for long service life and reduced total cost of ownership

Benchmark testing against leading competitors confirms Dinex DLTD's technical superiority and financial value, making it the ideal choice for modern heavy-duty exhaust systems.
