ò Power can be obtained with stronger engines. However, in order to maximize the efficiency, the aim is to obtain the same power with the engine rotation working at low RPMs. CEKSAN machines are producing the ultimate power while keeping the engine rotation between 1000 û 2000 RPMs, thus not only the users are saving fuel but also the machines are making less noise. ò Brushes are expenses. CEKSAN machines are designed in order to maximize the life of the brushes. The operator can adjust the pressure applied on the floor by the side brushes. An acceleration handle has been put inside the cabin, so the operator may also adjust the speed of the auxiliary engine. ò Dust is another concern. Not only the vacuumed air is being sprayed with water all the way but, at the exit of the air, there is a second system that filters the air. ò Noise is a crucial aspect. All efforts have been made to produce silent machines that are able to sweep streets without disturbing anyone. All surfaces around the auxiliary engine are covered by special materials. All tests show that the noise has been decreased to minimum values like 65 decibels. ò CEKSAN is the first and only company that produces the water tank and oil tank together separately from all other parts in its truck mounted street sweepers. The water tank being next to the oil tank, serves as a cooler for the oil. ò Water pump is moved by a hydro motor independently from the sweeping system. So when it is necessary irrigation or medication can be done. ò The operator can easily conduct the machine from the control panels: the sweeping, discharge, and washing, safety functions from inside and outside the cab.
