📌 Product Overview
Accelerate your pavement marking preparation and achieve supreme material consistency with the DW400 Hydraulic Single-Cylinder Thermoplastic Pre-Heater. Specifically engineered as a high-efficiency hydraulic melting kettle, this robust unit upgrades traditional mechanical systems into a fully hydraulic transmission, offering faster melting speeds and effortless bi-directional control. It is the perfect professional companion for your walk-behind thermoplastic road marking machines (such as our DW960 model).
Built around a compact, high-strength steel chassis, the DW400 features a 300kg heavy-duty melting tank with an ultra-thick 10mm high-carbon steel bottom to withstand intense daily thermal stress without deformation. Driven by a powerful 7.7HP electric-start Changchai diesel engine, its hydraulic paddle-type agitator mixes dense, high-viscosity coatings smoothly. With a lightweight footprint (300 kg net weight) and easy skid-mounted transportability, it stands out as the ultimate budget-friendly choice for parking lots, factories, residential areas, gas stations, rural roads, and municipal striping projects.
📌 Core Engineering & Pro Benefits
⚙️ Full Hydraulic Transmission & Stepless Speed Control
Unlike rigid mechanical gearboxes that wear out under heavy loads, the DW400 utilizes an advanced BM-type high-speed hydraulic motor paired with a 40L hydraulic oil tank. Managed by an integrated multi-channel hydraulic control valve, it provides butter-smooth, stepless variable speed mixing to process dense structural coatings flawlessly.
🔄 Rapid Bi-Directional (Forward/Reverse) Mixing
The smart hydraulic system allows operators to alternate the mixing blades between forward and reverse rotation instantly. This dual-direction agitation breaks up heavy paint clumps rapidly, increases heat distribution efficiency, and shaves precious minutes off your batch-melting cycles.
🏗️ 300kg Heavy-Duty Tank & 10mm High-Carbon Steel Bottom
The melting kettle boasts a solid 300kg material capacity optimized for daily efficiency. The bottom of the tank is forged from 10mm thick premium high-carbon steel, offering exceptional heat resistance and preventing burn-through or warping. This industrial-grade metallurgy guarantees a massively extended service life.
🦺 Overload Overflow Valve Safety Armor
Job site security is fully protected. The integrated hydraulic line features a specially designed overload overflow valve to neutralize operator error. If the paint inside is not melted completely or a heavy blockage occurs, the valve automatically bleeds pressure to stop the agitation shaft safely, protecting the hydraulic pump and engine from damage.
🔥 Energy-Saving Direct-Injection LPG Burner & Isolation Cotton
Equipped with an advanced direct-injection stove burner fueled by Liquefied Petroleum Gas (LPG). The heavy-duty tank body is wrapped in premium needle-punched thermal insulation cotton, retaining internal temperatures perfectly while keeping the machine's exterior safe to touch.
