SCU Surface Cleaning Unit

DYNASET SCU Surface Cleaning Unit converts the hydraulic power of a mobile machine into an effective surface cleaning and suction power. 

The SCU Surface Cleaning Unit is designed to efficiently clean large flat surfaces, such as parking garages, terminal areas, and paved market spaces. This unit combines high-pressure washing with a vacuum system that collects dirty water for recycling, leaving behind a clean, almost dry surface. Its all-in-one functionality ensures mess-free cleaning, making it ideal for large indoor and outdoor areas without splashing dirt, water, or debris onto the surroundings.

How Does the Surface Cleaning Unit Work?

The SCU Surface Cleaning Unit uses the hydraulic system of the carrier machine as its power source. It generates high-pressure water for surface cleaning and employs a powerful vacuum to collect the washing water. 

  1. Hydraulic oil flow from the carrier machine’s hydraulic system is directed into the HMV Hydraulic Modular Valve System, which distributes it to hydraulic components such as the HPW Hydraulic High-Pressure Water Pump and the HCF Hydraulic Centrifugal Fan.
  2. The HPW Hydraulic High-Pressure Water Pump draws water from a reservoir and sprays it at high pressure through rotating flat nozzles onto the surface being cleaned. 
  3. The SCU Surface Cleaning Unit is equipped with a protective cover that prevents water, dirt, and debris from spreading to the surrounding environment. 
  4. The HCF Hydraulic Centrifugal Fan vacuums water and dirt from the surface, depositing them into an integrated container for recycling. 
  5. Optionally, high-pressure water can be directed to a frontal washing pipe for street cleaning or a washing pistol for general pressure-washing tasks. 
  6. Functions such as suction can be activated or deactivated based on the specific cleaning requirements.
