Simplex Big is a series of automatic parts washers featuring rotary baskets, PLC control, and touchscreen operation that efficiently clean medium to large mechanical components using upper, lower, and side nozzles while the platform rotates slowly via a gear motor with torque limiter. The Simplex Big is available in two configurations: the standard version with a single tank for washing, and the Simplex Big 2B with dual tanks that enables both washing and rinsing in separate processes. The PLC management system offers extensive customization possibilities through a wide range of accessories for various industrial cleaning needs.
