Condition: new, functionality: fully functional, total length: 1,200 mm, total height: 2,100 mm, total width: 2,500 mm, empty load weight: 750 kg, input voltage: 400 V, water tank capacity: 400 l, warranty duration: 12 months, DPF DUO PREMIUM = CLEANING CABIN + DRYER FOR DPF/FAP FILTERS This set of devices allows for maximum optimization of the regeneration process. A well-organized operator can work with three filters simultaneously. Washes Dries Advantages of the DPF DUO Premium: Kodpfxjxm Szqe Ahvsww -> A separate dryer doubles work efficiency -> We are the only ones to offer a large-diameter hose that connects to the DPF. A larger diameter = more water = more effective cleaning -> Our filter mounting system is free of elements placed inside the DPF filter tube that could block the water flow. This allows the full performance of the water and air pump to be utilized, shortening regeneration time. -> The large cabin provides the freedom to mount the cleaned filter. The operator, based on their experience, can choose the position in which the filter will be washed. -> Protection against excessive pressure in the filter during cleaning -> Protection against lack of airflow through the filter during drying -> Possibility to individually set the cleaning program according to the filter capacity -> Stable securing of the filter during drying -> Three-stage dirty water filtration system -> Water heating controller -> Insulated water tank -> Training at the customer's site can be provided The device enables the removal of soot and ash from DPF/FAP filters without negatively impacting the filter structure, restoring up to 99% of the nominal flow rate. Our technicians have dedicated significant effort to ensure that both the cleaning procedures and the detergents used are safe for the environment and machine operators. The operator checks the filter for mechanical damage using an endoscopic camera. If signs of melting, ceramic core cracks, or other apparent mechanical damage interfering with the DPF are detected, regeneration will not be possible. The regeneration process takes place in a closed chamber equipped with filters preventing harmful contaminants from escaping into the environment. Water with cleaning fluid circulates in a closed loop and is filtered throughout the process, significantly extending bath life. The DPF DUO Premium cleans filters using water, chemistry, and air. A precisely selected, computer-controlled sequence of water and detergent dosing, combined with air and impulses generated by compressed air, ensures high regeneration efficiency. After the cleaning process is complete, an additional device dries the filter with air at 90°C, ensuring complete evaporation of the cleaning solution. After drying, the machine performs a final backpressure measurement. This measurement can also be taken before cleaning, allowing subsequent comparison of backpressure values before and after the process. The device is equipped with a printer that allows generating a measurement report. The washing time for filters from passenger cars or light commercial vehicles is 20–40 minutes, which enables regeneration of up to a dozen filters in 8 hours. High efficiency combined with low operating costs guarantees a rapid return on investment.
