In 2022, Otomatic set itself apart from competitors, who traditionally align with either the hydrodynamic (wet) or the pneumatic air knife (bake&blow) methods for DPF cleaning, by unveiling an innovative hybrid approach.
This pioneering hybrid method, patented under the name DPF-hybrid™, skillfully merges the strengths of both hydrodynamic and pneumatic techniques while effectively overcoming their limitations within a single, unified machine. This strategic integration not only enhances cleaning efficiency but also positions Otomatic as a leader in DPF cleaning technology, offering a versatile solution that addresses a broad spectrum of cleaning needs.
Otomatic's innovative approach to DPF cleaning effectively marries the advantages of the two most popular methods—hydrodynamic and pneumatic—into a single, integrated machine. This pioneering hybrid method is a result of merging the water-based cleaning capabilities of the hydrodynamic method with the air-based efficiency of the pneumatic method, creating a versatile and comprehensive cleaning process.
The hybrid cleaning process incorporates both methods sequentially within one cycle:
Initially, water mixed with detergent is propelled at high velocity, utilizing the friction of the water jet for washing and softening the particulate matter.
Subsequently, an intensified pulse of compressed air is employed to eject any remaining dirt particles from the filter channels, left over from the wet cleaning phase.
During the initial wet cleaning stage, the pulse of compressed air plays a crucial role in augmenting the water jet's pressure, thereby enhancing the friction and effectiveness of the cleaning solution. In the drying phase, this same compressed air pulse transitions into a primary cleaning agent, offering an additional layer of cleaning efficacy.
Unlike its role in the wet cleaning phase, where the air pulse primarily supports and strengthens the cleaning action of the water, in the drying process, it emerges as a standalone cleaning agent, showcasing the hybrid method's dynamic and adaptable nature.
When loose soot and ash mix with water inside the filter, they form sludge, creating a significant pressure barrier. This barrier can lead to the breaking of the DPF's ceramic monolith.
To prevent this, the Turbo Air Pulse program is designed to prepare the DPF for the subsequent cleaning phase. It effectively dislodges ash and soot from the channels, ensuring the water solution used in the next step can follow the "easiest" path through the filter's porous walls, optimizing the cleaning process.
The specialized cleaning fluid is designed to flow effortlessly through the filter brick, or monolith, via its clear outlet channels before seeping through the microscopic porous walls that separate the monolith channels, targeting the dirty inlet channels for thorough cleaning. This fluid's composition is engineered to soften the highly compressed and adhered particulates lodged within both the filter's inlet channels and its microporous walls.
The inclusion of carefully chosen surfactants in the formula significantly reduces the surface tension of the water-based solution, enhancing the fluid's ability to penetrate the filter's tiny pores. This capability, coupled with the effectiveness of hydrodynamic washing, ensures that all impurities are meticulously removed from the surface being cleaned.
Furthermore, the fluid's precisely calibrated viscosity means that the movement of its molecules mimics that of friction, facilitating an even deeper and more effective cleaning process. This meticulous approach to DPF cleaning ensures optimal performance and longevity of the filter.
Thanks to its patented "air pulse drying process," complete removal of any remaining sludge within the DPF filter—originating from the combination of loose soot and ash with water—is guaranteed. This innovative technique eliminates the risk associated with the evaporation of dirty rinse water and the potential accumulation of residual dirt particles in the cleaned channels of the filter.
Should any ash and soot particles not be thoroughly removed during the wet cleaning phase, this unique drying process ensures that these residues are expelled from the filter channels as shrunken, dried particles. This method effectively minimizes the risk of blockage, maintaining the optimal performance and longevity of the DPF filter.
The "automatic safety pressure valve" offers a high-pressure escape route, effectively preventing hydraulic pulse fracturing of the ceramic substrate.
Our comprehensive "anti-hydraulic fracturing" system, featuring a safety valve, a pressure sensor, and a control inverter for the water pump, ensures the safe removal of dissolved ash from the filter.
By employing an air pulse to dislodge loose soot and ash before wet cleaning, we diminish the hydraulic force applied during the cleaning process. This reduction is facilitated through either a compressed air gun nozzle or our exclusive "Air Pulse Program."
Thanks to our innovative "air pulse drying process," we guarantee the thorough removal of any sludge, formed from loose soot and ash mixed with water, from the filter's interior.
Our process ensures that the micropores of the Diesel Particulate Filter (DPF) remain free of messy sludge.
We eliminate the risk associated with the evaporation of dirty rinse water and the subsequent accumulation of leftover dirt particles within the filter's cleaning channels.
Should any ashes remain post-wet cleaning, we expel these residues from the filter channels as compacted, dried particles.
Our method achieves markedly superior cleaning results for DPFs when compared to conventional techniques. The measurement of air flow back pressure through the filter channels indicates the superior efficiency of our hybrid approach over both hydrodynamic and pneumatic methods.
The use of our system ensures the workshop air remains free from hazardous particle contamination, unlike the "Air Knife" solution.
Handling wet-cleaning sludge becomes effortless with the DPF Platinum's internal filtration system.
In our system, the wet-cleaning sludge is captured in the filter tank on cartridges that are easy to replace, enhancing the final filtration effect.
Our closed-loop operation system eliminates the need for a direct connection to a tap water source, making the process more efficient and self-contained.
The workshop space is maximized thanks to our all-in-one machine that encompasses cleaning, testing, drying, report printing, and filtration systems in a single unit.
Energy efficiency is significantly improved by shortening the duration of the complete cleaning cycle, leading to faster turnaround times and reduced energy consumption.
By introducing an innovative DPF cleaning service, businesses can enhance their competitive edge in the market.
More effective cleaning techniques lead to a reduction in customer complaints, boosting overall satisfaction.
Superior cleaning outcomes for DPFs, achieved through advanced methods, not only elevate the quality of service but also its cost-efficiency, providing a significant advantage over traditional cleaning approaches.
