3. Roll-Over Wash Systems These machines are popular in full-service car washes, where the vehicle is stationary while the machine rolls over it. Prices for these systems can start around $25,000 and reach up to $100,000 or more, especially for high-capacity models that include multiple washing and drying stages.

In recent years, the automotive industry has seen significant advancements in technology aimed at enhancing efficiency and sustainability. Among these innovations is the water machine for car washes, which plays a crucial role in improving the car cleaning process while conserving resources. This system is not only practical but also environmentally friendly, making it a popular choice for car wash operators and vehicle owners alike.
One of the most significant advantages of a high pressure vehicle washer is its ability to save time. Conventional hand washing can be labor-intensive and time-consuming, often requiring several buckets of water, sponges, and brushes. In contrast, a pressure washer can significantly reduce washing time to just a few minutes. The powerful spray can efficiently cover large areas, breaking down stubborn dirt and mud more quickly than manual methods.
Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
