TVR / NVK

Maximum Flexbility

• Thanks to its modular design, the thermal exhaust air purification system can be adapted to suit the roasting process, offering maximum flexibility for a wide range of purification requirements. 

Maximum Cleaning Efficiency

• Catalytic treatment of the exhaust air flow after thermal pre-cleaning significantly reduces visible organic roasting exhaust gases and product-specific odors, guaranteeing maximum cleaning efficiency.

Maximum Performance

• The use of a low-temperature catalyst reduces energy consumption while ensuring high purification performance and a significant reduction in NOx emissions.

PROBAT’s emission treatment systems are customized to meet specific roasting processes, ensuring that they can address a wide range of exhaust air purification requirements worldwide. Our modular exhaust air treatment solutions can be easily adapted, with options such as catalytic post-combustion for enhanced performance. Our portfolio includes solutions ranging from thermal pre-cleaners to advanced systems that combine thermal pre-cleaning with low-temperature catalytic post-combustion.

In the TVR thermal pre-cleaner, roasting exhaust air is heated to approximately 450°C with the help of an additional forced-air burner. At these elevated temperatures, visible organic roasting gases and product-specific odors are oxidized and significantly reduced, improving air quality.

For areas with particularly strict environmental regulations, the TVR system can be equipped with the NVK catalytic post-combustion system. After thermal pre-cleaning, the exhaust air passes through a catalytic converter, where both the temperature increase and catalytic reaction further reduce emissions.
