A frequency controlled screw compressor. By changing the speed of both motor and air end the SLF can operate the air end in its specifically optimum range and adapt the compressed air output to the actual needs. Expensive idling times and motor switches are avoided. At the same time a smaller pressure band can be set, also helping to save enrgy.
Special benefit: By adjusting the air end speed by frequency regulation not only the FAD can be adjusted but also the pressure value! Usual frequency controlled screw compressors only change the FAD at a certain given maximum pressure. Lowering the pressure value did not result in a higher FAD. But with the SLF adjusting the pressure value will at the same time result in an adjustment of the maximum possible FAD! This way a 13 bar model easily can be switched to an 8 bar model including the higher volume flow of an 8 bar machine. There are no alterings or constructive changes necessary. All pressure values can be served with one machine.
The sit-on stacker is one of the rider stackers. Gives ergonomic handling at a low cost.
Suitable for mixed handling, stacking/transfer with continuous driving time not exceeding 3 hours.
XJN (Junior) has the smallest turning radius.
XSN (Senior) has the biggest battery.
