Karcher HDS 13/20 4 S Hot Water High Pressure Cleaner
The Karcher HDS 13/20-4 S represents the absolute pinnacle of the Karcher Super Class range, delivering extreme hot water cleaning power for high-intensity, industrial applications. Powered by a heavy-duty 9.3 kW water-cooled electric motor, it blasts out an exceptional 1300 litres per hour water flow at up to 200 bar (2900 PSI), allowing for simultaneous two-spray lance operation to slash industrial cleaning times in half.
Ideal For:
-
Large Commercial Fleet Depots: Rapidly cleaning multiple B-double trucks, coaches, or rail rolling stock simultaneously.
-
Heavy Mining & Machinery Maintenance: Stripping baked-on grease, heavy hydraulic oils, and impacted mud from earthmoving machinery.
-
Large-Scale Agriculture: Sanitizing extensive food production plants, grain silos, and multi-facility livestock infrastructure.
-
Marine & Port Operations: Clearing marine growth, salt crusting, and heavy lubricants from ships, docks, and port equipment.
Karcher HDS 13/20 4 S Hot Water High Pressure Cleaner Features
- 4-pole water-cooled motor (9.3 kW) – Low-speed operation dramatically reduces mechanical wear and heat — designed for long continuous shifts without performance degradation.
- 3-piston ceramic axial pump – Ceramic pistons resist abrasion and scale, delivering consistent high-pressure output session after session — far outlasting standard metal pistons.
- Up to 155°C operating temperature – Near-steam temperatures break down the most resistant grease, oil, and biological residues — enabling chemical-free or low-chemical cleaning protocols.
- Dual spray lance operation – Connect two operators simultaneously to double cleaning throughput on large surfaces, vehicle fleets, or production facilities without needing a second machine.
- EASY!Force Advanced trigger gun – Uses the recoil force of the high-pressure jet to reduce operator holding force to zero — eliminating hand and wrist fatigue across full working shifts.
- Servo control on the lance – Pressure and water volume adjustable directly at the spray gun — operators fine-tune cleaning intensity without returning to the machine.
- Large LED service display – Central dashboard shows fuel level, detergent level, system care status, and service interval data in real time — preventing unplanned breakdowns.
- Dual detergent tanks – Switch between two cleaning agents without stopping — auto-rinse at the zero position keeps detergent lines clean and prevents cross-contamination.
- eco!efficiency mode – Optimised burner cycles at 60°C maintain full water flow while cutting fuel use and CO₂ emissions by 20% — lowering operating costs on every job.
- Service switch — water hardness control – Four selectable hardness settings protect the heating coil from limescale, extending the life of the burner system and reducing service frequency.
- Soft Damping System (SDS) – Absorbs pressure peaks and vibration in the high-pressure circuit, protecting the pump and reducing operator fatigue during continuous operation.
- EASY!Lock quick-release fittings – Change lances, nozzles, and hose connections five times faster than conventional screw systems — slashing setup and accessory changeover time.
