The VEMO V30-68-0001 Diesel Exhaust Fluid (DEF) Heater is engineered to maintain optimal temperatures within the DEF tank of Mercedes-Benz GL series vehicles, including the GL320, GL350, GL450, and GL550 models. This component is essential for ensuring the efficient operation of the vehicle's selective catalytic reduction (SCR) system, which reduces nitrogen oxide emissions by injecting DEF into the exhaust stream. By keeping the DEF at the appropriate temperature, the heater ensures that the SCR system functions effectively, thereby maintaining compliance with environmental regulations and preserving engine performance. Constructed with high-quality materials, the VEMO V30-68-0001 is designed for durability and reliability, offering a direct replacement for the original equipment. Its precise engineering ensures seamless integration with the vehicle's existing systems, facilitating straightforward installation and minimizing downtime. Fleet operators can rely on this heater to maintain the performance and longevity of their vehicles, reducing the likelihood of DEF-related issues and associated maintenance costs. By investing in the VEMO V30-68-0001, businesses can ensure their fleet remains operational and compliant with emission standards, thereby supporting both environmental responsibility and operational efficiency.
