Kranzle Therm RP-1200 Hot Water Pressure Washer

Upgrade to the Kranzle Therm RP-1200 for Maximum Heavy Duty Pressure

When your operations demand maximum pressure and the ability to move serious volume of hot water across heavy industrial applications, the Kranzle Therm RP1200 is the machine for the job.

Featuring a new in-line crankshaft pump, 2,755 psi at 20 L/min and temperatures up to 140°C, this three-phase 415V machine is purpose-built for construction sites, agricultural operations, and heavy machinery cleaning where sheer cleaning throughput is the priority. 

Key Features & Benefits of the Kranzle Therm RP1200

• 20 L/min with a new in-line crankshaft pump — serious flow for serious operations — significantly more water volume per minute than the 895 series, making it the right step up for large-scale construction, agricultural, and industrial cleaning where throughput is the priority and a standard three-phase machine simply can't keep pace

• Stainless steel coil for food-grade applications and harsh water conditions — the stainless steel heating coil makes the RP1200 the right choice for food processing plants, harsh or corrosive water supplies, or any application where coil longevity and compliance with food-grade cleaning standards are a requirement.

• Comprehensive 4-way safety system with Total-Stop and optical flame monitoring — Total-Stop automatic control with delayed motor cut-out, optical flame monitoring, low fuel cut-out for the burner, water flow monitoring, thermal overload switch, and safety thermostat all work together to protect the machine and operator across heavy continuous-use sessions.

• Digital operating panel with precise temperature and burner control — full digital panel with hour meter, adjustable burner performance, and thermostat regulation in °C gives operators complete control over machine performance, making it easy to optimise for each application and contamination type.

• Slow-speed 1,400 rpm heavy-duty 4-pole motor for maximum service life — running at a fraction of the speed of high-speed alternatives, this motor runs cooler, quieter, and longer, delivering the reliability and longevity you expect from a machine engineered and built in Germany.

Why Choose a Kranzle Hot Water Pressure Washer?

Kranzle pressure washers are German-engineered machines built to a standard well above the typical commercial market. Slow-speed motors, precision-built pumps, non-seamed vertical coils, and high-quality componentry throughout deliver a service life that significantly outlasts comparable machines — and every Kranzle is designed to be serviced and repaired, not thrown away, with a full spare parts supply and Australian-based technical support backed by Powerblast.

Cold water pressure washers handle general cleaning, dust suppression, and loose surface dirt effectively. But when the job involves heavy grease, oil, biological contamination, or surfaces that need sanitising without chemicals, hot water is the only practical solution. Hot water breaks down hydrocarbons and organic matter at a molecular level — cleaning faster, more thoroughly, and with significantly less chemical use than cold water alone. For any operation where grease, oil, or heavy contamination is a daily reality, a Kranzle hot water pressure washer is the right long-term investment.
