Product information and benefits

Our cold water high-pressure cleaner for stationary continuous operation can be operated with a water inlet temperature of up to 60°C. With an operating pressure of 180 bar and a flow rate of 800 l/h it is suitable for cleaning machinery or production facilities. The unit is equipped with a crankshaft pump featuring a brass cylinder head and a 4-pole, slow-running electric motor. The housing and frame are constructed from powder-coated steel. The machine includes a detergent suction system with a dosing valve and low-level indicator, as well as a water supply tank with dry-run protection and level indicator. Electronic monitoring with displays for errors and maintenance intervals supports safe operation. Control is provided via a large rotary switch; the design is tailored for straightforward installation and maintenance. Accessories such as operating hours counters, remote controls, or automatic pressure relief are not included in the scope of delivery and can be added individually depending on the point of use.
