Automatic Grabs and Clamshells

At the beginning of 2014, we have implemented a new programming process taking into account the efficiency and profitability parameters of your installation. This process meets the increasingly demanding criteria of your customers. A touchscreen human/machine interface allows your technician to program the machine control and automation of the sludge disposal operation.
