Pulp and Paper

Control and supervision solution for production facilities

A major Brazilian company in the pulp and paper sector identified Altus as having the technological potential needed to upgrade the automation plant responsible for managing the evaporation system in one of its industrial units.

Precise control and remote supervision of production processes

Using the NX Series programmable controllers, the developed project is responsible for controlling the pre-evaporation stage of the unit, which has the function of changing the concentration of solid particles in the Black Liquor extracted from the wood.

Altus’ solution implemented a programmable NX3020 controller with 136 I/O points (64 AI, 24 AO, 32 DI, and 16 DO), communicating via the MODBUS TCP protocol, ideal for high demand counting applications. The system also retained some of the existing QK801 and AL-600 equipment, which had been part of the plant’s previous automation setup

Enhanced availability with advanced features and precise diagnostics

Simple maintenance, made possible by the OTD (One Touch Diag) function, which provides quick diagnostics on the equipment's front display, and ESP (Easy Plug System), a practical and safe mechanism for inserting and removing I/O modules, in addition to the ease of integration with the series' native communication protocols, such as PROFIBUS and MODBUS, makes the NX Series controllers the best choice for replacing legacy automation equipment.
