Other General Parts/AdBlue Tank Parts

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized AdBlue tank parts within our Other General Parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and electronic-chemical control configurations, ensuring that every component meets rigorous Komatsu standards for emissions defense and preventive maintenance:
• Machine & Heavy-Duty SCR System Compatibility: Engineered for a broad range of Komatsu heavy-duty equipment, our products ensure exact fluid pressure tolerances, electrical resistance parameters, and mechanical mounting definitions for a 100% perfect match, rapid replacement, and factory-grade performance.
• Complete Heavy-Duty AdBlue System Range: 1. AdBlue Pumps & Dosing Modules: Designed for high-pressure precise injection of urea solution, featuring exceptional anti-crystallization and accurate flow control capabilities; 2. Multi-Functional Sensors: Integrated level, temperature, and concentration sensors formulated to monitor tank fluid levels, prevent dry burning, and track solution quality; 3. Anti-Freezing Heating Lines & Tank Caps: Satisfying cold-climate mining operations through combined coolant/electrical heating functions and dustproof locking caps.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu AdBlue components alongside rigorous high-performance aftermarket alternatives, delivering exceptional operational reliability and extended service lifespan at a cost-effective procurement point for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global emissions control component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international equipment owners and repair facilities.
• Massive Inventory and Cross-Reference: We maintain large-volume stock of hundreds of AdBlue pumps, sensors, and heating lines matching Komatsu mainstream Tier 4 models. Backed by barcode-enabled intelligent warehousing and Komatsu cross-reference databases, we guarantee precise matching and immediate dispatch upon order confirmation to fulfill routine maintenance and rapid replenishment needs for overseas fleet workshops and minimize equipment downtime caused by emissions system faults triggering speed reductions and power derates halting complete machine operations.
• Anti-Static and Anti-Vibration Packaging: We implement specialized industrial packaging standards for urea sensors and electronic pump modules utilizing independent anti-static vacuum plastic sealing and thickened shock-absorbing foam enclosures. Exterior packaging incorporates multi-layer bubble wrap and custom aviation-grade crush-resistant foam boxes sealed securely to ensure zero circuit short-circuiting, probe bending, or housing fracture during transcontinental ocean freight under salt spray, high temperatures, and rough cargo handling.
• Palletized and Heavy-Duty Crated Protection: Bulk heavy-duty urea tank assembly and line shipments are stacked on standardized pallet configurations, secured with high-strength stretch wrap in a criss-cross pattern, and reinforced with heavy-duty export fumigated wooden crates or thick-walled reinforced boxes to guarantee absolute safety during long-distance transcontinental transport.
• Consolidated Sourcing for SCR and Aftertreatment Overhaul Kits: We support overseas clients by consolidating AdBlue pumps and sensors alongside matching urea filter elements, specialized line fittings, and sealing O-rings into precise bundled full-set SCR system maintenance kits, achieving a one-stop purchasing model that pairs environmental aftertreatment service supplies while significantly reducing comprehensive logistics costs for overseas workshops.

Engineering Solutions & Technical Support
Our technical framework focuses on resolving field-level operational challenges to eliminate equipment downtime, moving beyond simple parts distribution to deliver comprehensive engineering and service capabilities for asset health monitoring reliability.
• Application-Specific SCR & Anti-Crystallization Solutions: We address extreme jobsite challenges—such as high-temperature open-pit mines—where rapid urea evaporation produces dense white hard crystals that block lines and cause original urea injectors and hoses to experience carbonization failures, triggering Komatsu excavators to report aftertreatment fault codes and enforce engine torque derates. We also provide professional upgrades utilizing high-temperature coated anti-crystallization nozzles featuring smart purge and electric heating capabilities.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like frequent DEF level warnings, slow urea pump pressure build-up, or total pressure failure. This focuses on two critical protocols: 1. Warm Water Cleaning & Fluid Purity: Technicians must use 40°C to 50°C warm water to dissolve crystals from nozzles and lines—strictly prohibiting hard metal tools to prevent port damage—while mandating ISO 22241 compliant high-purity automotive urea; 2. Low-Temperature Thaw & Purge Protection: Equipment directors must verify automated urea purge and heating functions during freezing winter shutdowns to prevent residual urea expansion from bursting pump bodies.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including SCR aftertreatment electrical schematic diagrams, urea line quick-fitting disassembly specifications, diagnostic trouble code reference manuals, and emissions maintenance visual documentation, assisting overseas technical personnel in executing standardized construction.
