Three-stand modular carwash

Three-stand modular carwash

Modular three-stand carwash  is destined for localization with moderate traffic, like small and medium cities, settlements, next to small markets. It can be used also to complete the petrol or gas station offer.

The kit includes three-stand BKF Carwash module, steel construction with full equipment, the repeatable project. Construction works are performed by the investor on the basis of a repetitive project.

The technical module includes following standard equipment

    Control panel containing the following standard equipment on  both sides of the carwash module:
  • Electronic slot for coins and tokens
  • Time display unit (electronic) 
  • Information push buttons, backlit adequately to the program in use

    5 washing programs (standard):
  • Program 0: Spraying the chemical over rims. It helps to remove carbon deposits and tarnish from the brake blocks; softened and demineralized water.
  • Program 1: Turbo spray – spraying the chemical with softened and demineralized water, preparation for touch-less washing ( softening hard dirt deposits)
  • Program 2: Touch-less pressure wash (basic, original BKF technology) – water filtrated from mechanical impurities - softened, a chemical agent – powder neutral to the paint, dozed continuously (tenside technology) – high temperature helps to dissolve fatty tarnishes
  • Program 3: Flushing of remaining impurities and chemicals with clean water after touch-less washing
  • Program 4: Preservation with a polymeric agent – filtrated softened water consisting a latest-generation polymeric agent. The polymer covers clean paint with a hard thin layer. In the high temperature it sticks to the carbody.
  • Program 5: Glazing  – Flushing the carbody with softened and deminiralized water containing a drying – glazing compound, which prevents it from stains or sagging. This step finishes the previous stepc. It allows to skip wiping and/or drying.
    Outer antifreezing system
  • Antifreezing water tank, stainless steel.
  • Water circulation initiated by an outdoor electronic thermostat
  • Antifreezing pump, charging the circulation system
  • Pressure regulator to control water pressure and supply, reduces losses
  • Net filter installed on the inlet to the circulation system
  • Mechanical floating valve for automatic control of water level in the antifreezing tank.
Emergency antifreezing system, starts automatically on power failure. A Burkert solenoid valve opens to let the city water in which comes with the pressure from the water supply network. The water flows through the whole water system to the antifreezing tank.
In case there is no power for a longer time, excess of water leaves the antifreezing tank through an overflow  pipe to drain.

    Integrated lance holder connected to wtare cyrculation system

    Water filter with control manometer installed at inlet
