Functional specifications
PED Certified Steam Operation
Steam operation, certified to PED 2014/68/CE category II, distinguishes this professional 140°C steam pressure washer from traditional hot water versions. The high temperature improves effectiveness on oily residues, industrial scale, and complex contamination, making it ideal for structured production environments and high-intensity operations.
Water Suction from Integrated Tank
The tank-mounted water suction system with an inspectable cartridge filter allows for autonomy in the absence of a pressurized water supply . This configuration transforms the machine into a self-contained professional pressure washer, suitable for construction sites, industrial yards , and environments where direct water supply is unavailable.
Integrated Anti-Limescale Device with Dedicated Pump
The automatic anti-scale system with a 2.5L tank protects the boiler from deposits and scale, extending the life of the hot water industrial pressure washer and reducing maintenance costs in hard water areas. This is a strategic feature for continuous and professional use.
Flow Switch Operated Burner
The flow-controlled burner optimizes combustion activation based on actual water flow, improving energy efficiency and operational safety . This system enhances the thermal control of the 400V three-phase professional pressure washer, ensuring circuit stability and protection.
Electronic Temperature Regulation System
Electronic temperature management with low oscillation keeps the set value stable, optimizing the efficiency of the industrial hot water pressure washer and improving performance in technical cleaning on surfaces contaminated by oils and industrial residues.
Delayed Total Stop and General Stop System
The delayed Total Stop function automatically stops operation when the gun is released, limiting wear and energy consumption. The General Stop function for prolonged inactivity protects the machine when not in use, an essential feature in a professional pressure washer for intensive use.
Adjustable Low Pressure Detergent Suction
The professional, adjustable low-pressure detergent suction system allows the controlled use of chemical products for pre-washing and degreasing , improving the operational performance of the industrial hot water pressure washer in the automotive and industrial sectors.
Professional Safety Devices
The presence of a professional safety valve and integrated thermal protections guarantees compliance with the safety standards required for a high-performance industrial pressure washer, ensuring operational continuity in structured professional environments.
