Easy to handle, robust and powerful: stationary cold water cleaner with 800 l/h and 180 bar for continuous use in tough working conditions.
Our cold water cleaner for tough working conditions in stationary use is designed to handle water inlet temperatures up to 60 °C. With a pressure of 180 bar and a flow rate of 800 l/h, it is ideal for cleaning machines or production facilities. At the heart of the machine is the robust crankshaft pump with brass cylinder head and the 4-pole, low-speed electric motor. The housing and frame, which are made of powder-coated steel, also contribute to its durability. The machine has a detergent dosing valve and an empty tank indicator, as well as a water tank with dry-running protection, and here too the empty tank level is shown by an indicator. Safe operation is ensured by electronic monitoring that provides notifications of errors and maintenance intervals. A large rotary switch makes operation simple and convenient, and installation and maintenance are also designed with user-friendliness in mind. Extensive accessories such as timers, remote controls or automatic pressure relief are not included in the delivery, but can be selected at each point of use.
