Engineered for extreme operational environments, zero-downtime manufacturing, and compliance with stringent environmental standards.
Decarbonization, Total Cost of Ownership (TCO), and Thermal Thermodynamics in Modern Manufacturing
In modern industrial facilities—ranging from petro-chemical refineries and heavy shipbuilding yards to automated beverage bottling plants—cleaning is no longer merely a maintenance chore. It is a critical engineering process directly affecting operational uptime, thermodynamic efficiency, sanitary risk control, and equipment longevity. Industrial steam cleaning equipment and ultra-high-pressure water jetting systems represent the pinnacle of thermal-mechanical surface decontamination.
Unlike standard ambient cold-water washers, dry vapor steam generators (operating between 140°C and 180°C under 8 to 150+ bar pressure) harness the latent heat of vaporization. When high-temperature saturated steam strikes a contaminated substrate, thermal shock rapidly breaks the molecular bonds of heavy grease, polymers, vulcanized rubbers, and bio-films without necessitating aggressive chemical solvents. This micro-burst kinetic energy drastically reduces water consumption by up to 85% compared to traditional pressure washing, mitigating wastewater treatment expenses while providing instant thermal sanitization (achieving up to 99.999% microbial eradication).
Global procurement teams across North America, Europe, and Asia-Pacific face tightening environmental protocols such as the EU REACH standards, US EPA NPDES wastewater directives, and strict ESG carbon-footprint accounting. Consequently, modern industrial procurement is pivoting toward three main technology pillars:

30+ Years of Cleaning Mechanical System Research, Development & Global Manufacturing
Foshan Dulles Equipment Co., Ltd. was great experienced in cleaning mechanical system research and development for more than 30 years, which was one of the earliest companies to produce pressure washers. As the growing market greatly demand of clean and environmental products year by year, we speed up research and development work meanwhile commit to provide multi-aspect cleaning and environmental solutions to our customers. Early in 1995, the first general home pressure washer was developed.
In order to meet the different requirements from market demand, we continue to develop products which involve commercial and industrial pressure washers, explosion-proof high pressure cleaning machines, sewer machine drain cleaners, fog making machines, electric sewer cleaners, gasoline dredge cleaning machines, as well as intelligent fog making machines, etc.
Our products are widely applied in various areas, especially in industrial and chemical production, ship rust removal, municipal bridge engineering, mine and road dust removal, street cleaning, urban pipe dredging, and mobile car wash equipment, etc.
The series products have obtained 3C, CE and ISO certificates, and also design pattern certificates for pressure washers, high pressure pumps, fog making machines and more. Dulles products are well accepted by the market with advantages of unique and fashionable design, cost-effectiveness, high-level safety and stable performance, which has helped build a strong reputation and expand gradually into European and American markets from South and East Asia.

Why Global Enterprise Procurement Directs Engineering Contracts to Foshan Industrial Clusters
The Foshan manufacturing hub houses end-to-end supply chains—from high-grade ceramic plunger forging and stainless steel boiler welding to micro-chip controller assembly. This cluster effect drastically reduces component sourcing lead times from months to days.
Equipped with 5-axis CNC machining centers and dynamic balance testing rigs, manufacturers like Dulles achieve pump tolerances measured in microns. Automated testing ensures each triplex pump undergoes continuous hydro-static pressure testing prior to shipment.
By eliminating multi-layer intermediate distributors, international buyers secure heavy industrial-grade machines (e.g., 7000 PSI explosion-proof units) at a fraction of Western OEM pricing, accompanied by customized modular fittings and voltage adaptations (220V-690V, 50/60Hz).
Key Technical Parameters Every Industrial Plant Manager Must Evaluate
Hot Water Washers (Up to 90°C - 150°C): High flow rates (15-30 L/min) and high pressure (2,000 - 7,000 PSI). Best suited for heavy mud, sand, concrete, and thick oil layer removal on ship hulls and mining rigs.
Dry Vapor Steam (140°C - 180°C): Low water usage (2-5 L/min), micro-moisture (less than 5% water). Ideal for electrical cabinets, food processing conveyors, bottling lines, and sterile environments.
Operations in chemical plants, fuel storage hubs, and underground mining require certified explosion-proof motors, non-sparking brass/stainless pumps, sealed electrical cabinets (IP65/IP66), and static-dissipative high-pressure hoses to prevent accidental vapor ignition.
For liquid transfer in food, beverage, paint, and chemical processing, integrated pigging systems (such as ISO 2.5" Manual or DN65 Automatic Double-Launch Stations) clear pipelines with hygienic launchers, recovering valuable product while performing full CIP cycle flushes.
Field-Tested Performance Across Demanding Global Sectors
Marine environments require continuous removal of salt crusting, marine growth (barnacles), and oxidized paint coats. High-pressure jetting units (up to 7,000 PSI) utilizing triplex ceramic plunger pumps deliver continuous heavy-duty hydro-blasting on vessel dry docks.
Urban infrastructure demands specialized sewer pipe cleaner systems and gasoline/diesel dredge machines. High-pressure nozzles propel self-advancing hoses through underground municipal conduits to clear grease, roots, and hardened mineral scale.
Open-pit mines and heavy demolition sites generate hazardous airborne particulate matter. Intelligent fog making machines and thermal backpack foggers atomize micro-water droplets to bind airborne dust and reduce particulate concentrations to meet environmental health regulations.
Sanitary standards in brewing and dairy plants mandate CIP (Clean-In-Place) systems coupled with vertical fermentation tanks. Thermal steam and pigging units systematically sanitize internal pipe walls without disassembling delicate valves and joints.
Automated vehicle cleaning systems with smart pressure control deliver rapid exterior mud removal, chassis degreasing, and automated underbody washing for commercial logistics fleets and auto-detailing centers.
Viscous raw materials left inside pipeline runs cause severe production loss. Double-launch station automatic pigging systems (DN65) propel specialized projectiles to reclaim remaining liquid product, eliminating batch cross-contamination.
