Kränzle truck pressure washers are the commercial and industrial high pressure cleaners used to wash trucks, trailers and fleet vehicles. They are the larger machines in the range, running at 1,400 r.p.m and built for continuous use, day in and day out, in a wash bay. Every machine runs the same German Kränzle pump. The stainless steel cabinets and frames are built locally, adapting the machine to South African wash bays with a housing that does not corrode in a permanently wet working area. What lets a machine hold up to the repeated daily cycles of a working wash bay is the pump and the features that protect it – and it is on this that Kränzle guarantees a particularly long service life.

Cold water machines
| Machine | Flow | Pressure | Motor | Format |
|---|---|---|---|---|

| Kränzle Quadro 800 TST | 13.3 L/min | 250 bar | 5.5 kW | Mobile, hose reel |
| Kränzle Quadro 1000 TST | 16 L/min | 220 bar | 5.5 kW | Mobile, hose reel |
| Kränzle Quadro 1200 TST | 19 L/min | 180 bar | 5.5 kW | Mobile, hose reel |
| Kränzle Truckwash 3250 | 16 L/min | 220 bar | 5.5 kW | Stainless steel wall cabinet |
| Kränzle 3250 Hi-Cycle | 16 L/min | 220 bar | 5.5 kW | Wall cabinet; recycle tank, over-temp protection |
| Kränzle Core CW16/220 | 16 L/min | 220 bar | 5.5 kW | Open wall-mount |
| Kränzle 3250 Double Quadro 800 | 26 L/min | 250 bar | 2 × 5.5 kW | Mobile stainless frame, reservoir tank |
All machines run at 1,400 r.p.m on a 400V three-phase supply, with dry-run protection, total-stop and a trigger gun, lance and hose. The Kränzle Quadro 1000 and the Truckwash 3250 are the two most commonly used for truck washing, both running 16 L/min at 220 bar.
Hot water machines
Hot water is supplied two ways. The electrically heated Kränzle Electra range heats through elements with no burner exhaust, so it can be used indoors and in enclosed bays; outlet temperature is a function of heating output against water flow. The diesel-burner Kränzle Therm range holds an approximately 80 °C setpoint regardless of flow and draws mains power only for its pump motor, so it suits a yard without the heavy supply an Electra needs.
The Electra is available from 24 kW to 96 kW, drawing 40 A to 160 A on a 400V supply, and is built on either the 799 or the 3250 pump according to the flow and pressure needed – so each machine is configured to the wash bay rather than picked from a shelf. Outlet temperature depends on the heating output, the water flow and the inlet, so it rises with a warmer supply. 36 kW, 96 kW and all 525V builds are wall mount only. The diesel-burner range is the Kränzle Therm 715 Black (230V), Therm 890 and Therm 1017 (400V). Ask for the configuration that suits your supply and the work.
| Electra heating | Current | Flow | Pressure |
|---|---|---|---|
| 24 kW | 40 A | 10 L/min | 180 bar |
| 24 kW | 40 A | 13 L/min | 200 bar |
| 36 kW | 60 A | 10 L/min | 200 bar |
| 48 kW | 80 A | 13 L/min | 200 bar |
| 48 kW | 80 A | 16 L/min | 180 bar |
| 48 kW | 80 A | 19 L/min | 160 bar |
| 72 kW | 120 A | 13 L/min | 200 bar |
| 72 kW | 120 A | 16 L/min | 180 bar |
| 72 kW | 120 A | 19 L/min | 160 bar |
| 96 kW | 160 A | 16 L/min | 180 bar |
| 96 kW | 160 A | 19 L/min | 160 bar |
Motor runs at 1,400 r.p.m – approximately 4 kW on 799-based builds, 5.5 kW on 3250-based builds – with a water tank and low-level cut-out, supplied with a 10 m hose, gun and standard lance. A 525V version is available for mining (wall-mount only).
Frequently asked questions
Cold water or hot water for washing trucks?
Cold water at the correct pressure and flow handles general road grime and is the starting point for most fleets. Hot water is specified where the soiling is oily – diesel, grease and heavy road film – because heat dissolves oils that cold water leaves behind, so the chemical is used sparingly rather than doing the whole job.
Should the machine be chosen on pressure or on water flow?
Both, and separately. Pressure determines the impact force that breaks the bond between the dirt and the surface. Water flow determines how quickly the loosened contamination is flushed away. On a large vehicle the flow matters – there is a lot of surface to move dirt off – which is why the truck machines sit at the higher-flow end of the range.
Which machines carry a water tank, and what does it do?
The Kränzle Quadro, Truckwash 3250 and Electra machines carry a reservoir tank with a low level cut-out, as do the locally built stainless steel cabinet and wall-mounted systems. A float valve controls the incoming water, so the pump draws from a buffer rather than off a line that may surge or drop away, and the cut-out stops the machine rather than letting it run dry. Water starvation is the leading cause of high pressure cleaner damage across all brands.
Mobile or wall mounted?
Both. The same pump and motor platforms are supplied as mobile machines, on stainless steel frames, or built into locally manufactured stainless steel cabinets for a fixed wash bay – the Kränzle Truckwash 3250 is the cabinet build. A wall mounted installation can add a break tank and float valve, a control panel, remote hose reels or a swivel boom.
What supply does a truck pressure washer need?
230V single-phase on the smaller machines and 400V three-phase from approximately 12 L/min upward, with 525V available for underground mining as a special-order build. The machine needs roughly one third more water than the pump’s rated output – a 16 L/min pump wants about 21 L/min at the machine. Confirm voltage, phase, amperage and water supply before quoting.
