Cobra Europe Unveils DELTATHERM® T3 Premium – New Benchmark for Heat-Resistant Conveyor Belts

New compound delivers proven performance at continuous 240°C and peak temperatures up to 400°C in demanding applications such as coking plants and clinker lines

Piekary, Poland– 12/01/2025 – Cobra Europe today announced the launch of its DELTATHERM® T3 Premium heat-resistant conveyor belt compound, setting a new standard for performance and reliability in extreme-temperature conveying applications, including coking plants, foundries, and clinker lines.

While many belts are marketed as “heat resistant,” the industry has long lacked transparent, application-based data demonstrating how belts perform under real operating conditions. With T3 Premium, Cobra Europe has developed not only a new compound, but also a comprehensive test program that closely replicates the thermal stresses seen in the field.

“Our customers don’t just need a datasheet—they need proof,” said Robert Heukelom, President, Cobra Europe. “With DELTATHERM T3 Premium, we have validated performance using realistic test scenarios and then confirmed it in our laboratory. The result is a belt that protects the entire construction, not just the cover, when temperatures spike.”

Engineered for Extreme Temperatures

DELTATHERM T3 Premium is designed for high-demand heat applications and features:

•    Resistance to peak temperatures up to 400°C

•    Continuous material temperatures of 240°C, and up to 280°C under defined conditions

•    A specially developed cover rubber with outstanding heat-resistance parameters

•    A specially developed core rubber to protect the carcass and maintain adhesion

•    Availability with both EP and PP fabric carcasses

By optimizing both the cover and the core rubber, T3 Premium is engineered to shield the entire belt configuration during continuous operation, thermal cycling, and short-term temperature peaks. Cobra Europe is also extending this technology to slick belts, elevator belts, Chevron belts and Blue belts, using the same rigorous testing methodologies.

Beyond Standard Lab Tests: Real-World Thermal Testing

To verify performance, Cobra Europe has implemented a series of test procedures that simulate realistic conveyor conditions rather than relying solely on static, laboratory-only measurements.

Key elements of the test program include:

•    Continuous exposure tests at 240°C simulating normal operation and conveyor stops with hot material remaining on the belt

•    Cyclic heating and cooling tests at 240°C to mimic real plant load cycles

•    Short-term exposure tests at 300°C to reflect brief high-temperature surges

•    Extreme peak tests at 400°C to confirm safety margins in the most demanding conditions

Across all scenarios, T3 Premium maintained adhesion and rubber properties within Cobra’s defined safety range, confirming that the belt can withstand both steady-state and peak temperatures without critical loss of performance.

“The market has talked about heat resistance for years, but we wanted to quantify it in a way that truly reflects what happens in a coking plant or clinker line,” added Heukelom, President. “Our T3 Premium test matrix was built around the real pain points we see at customer sites.”

Proven in a Critical Coking Plant Application

DELTATHERM T3 Premium has already proven itself in a demanding installation at the JSW KOKS coking plant, where it replaced a previous heat-resistant belt.

Application highlights:

•    Plant: JSW KOKS (coking plant)

•    Belt length: 270 m

•    Belt type: DELTATHERM 1000/4 1400 10+3 T3 Premium

•    Product: Hot coke from the furnace

Although process specifications indicate product temperatures should be below 250°C at the belt, real measurements have shown material temperatures exceeding 400°C. Additional risk factors include:

•    Coke with an ignition temperature above 600°C

•    Non-automatic water cooling

•    No active temperature control prior to loading

•    No bypass conveyor, making this belt a single critical path in the process

Despite these conditions, T3 Premium has delivered stable performance, reinforcing its suitability for high-risk, no-redundancy applications where belt failure is not an option.

Raising the Bar for Heat-Resistant Conveyors

With DELTATHERM T3 Premium, Cobra Europe is offering operators:

•    Documented heat resistance under realistic thermal loads

•    Protection of cover, core, and carcass for longer service life

•    Confidence in continuous operation at elevated temperatures

•    A proven solution for coking plants, foundries, cement and clinker operations, and other high-temperature environments

“DELTATHERM T3 Premium is the result of listening closely to our customers and investing in a test program that reflects their reality,” said Mike Schmidt, President, Cobra America “We believe it sets a new benchmark for safety, reliability, and transparency in heat-resistant conveyor technology.”
