Production of AUS32 catalytic fluid (similar to AdBlue) on a DEF CT500 automatic unit. AUS32 catalytic fluid (similar to AdBlue) is a special liquid reagent (an aqueous solution of 32.5% urea and 67.5% demineralized water) used in modern diesel engines with selective catalytic reduction (SCR) systems. It is designed to reduce harmful nitrogen oxide emissions by 90% or more, ensuring compliance with Euro 5 and Euro 6 emission standards. AUS32 consumption typically accounts for 4-7% of an engine's diesel fuel consumption. Our technology utilizes a cavitation reactor to instantly dissolve urea in water. In the DEF CT500 unit, a mixture of urea and water in the required proportions is pumped through a cavitation reactor. In this case, solid urea crystals are effectively broken up by shock waves from the implosion of cavitation bubbles into nanoparticles. In this state, the surface area to volume ratio of urea becomes so high that dissolution of this dust in water occurs within seconds. The cavitation energy is ultimately converted into thermal energy, allowing the dissolution process to occur without additional heating. AdBlue Specifications: • Capacity – 500 liters per hour (up to 12,000 liters per day) • Energy consumption – 3.5 kWh (0.007 kWh/liter) • Dimensions (length, width, height) – 3 m x 3 m x 1.65 m • Total weight – 450 kg • Material – stainless steel Advantages of the cavitation method (patented U2025 06080) 1.

The process occurs at a low temperature and does not require additional heating. 7. Automatic Quality Control of the Finished Product Operating Principle of the AUS32 Production System: Water [WATER] from an external source is fed into the reverse osmosis purification unit [1] and then pumped by a built-in pump into the buffer tank [2]. From the buffer tank [2], the purified water is pumped by a high-performance pump into the AUS32 (AdBlue type) preparation tank [3]. The volume of water required to prepare the solution is controlled by a special sensor installed in the tank [3]. After filling the tank [3] with water, urea [UREA] is fed into the tank via a screw dispenser [4]. Due to the special design of the tank [3], urea does not enter the water filling the tank, but is fed directly with the water into the cavitation reactor [5], thereby compensating for the temperature drop due to the endothermic reaction. The urea and water solution from the reactor is returned to the tank [3]. An industrial refractometer [6] monitors the solution concentration in tank [3] in real time. Once the solution concentration reaches 32.5%, the supply of urea [UREA] to tank [3] is stopped, and the resulting solution (~500 liters) is pumped into AUS32 storage tanks (like AdBlue) in the production warehouse. The entire process is computer-controlled, using a PLC (programmable logic controller), eliminating human error.
