Alldrives & Controls Ltd Unitronics Timber Industry

“The most cost effective and reliable way to fill the entry level PLC/HMI/SCADA bracket in the market”   – Henco Viljoen

At Alldrives & Controls Ltd we continually support the industries we work with creating success stories day after day through the products we sell. Currently most of our success stories have been surrounding Unitronics products. This particular case study tells the story of a family run business specialising in the Timber industry.

The wood industry or lumber industry is an economic sector concerned with forestry, logging, timber trade, and the production of forest products, timber/lumber, primary forest and wood products (e.g. furniture) and secondary products like wood pulp for the pulp and paper industry. When making a product from timber to sell to the general public the wood has to be dry cured in a kiln. This stops rotting and deterioration of the product of your labor. This process of drying the wood is sometimes a lengthy process that a trader would have to do him/ herself, wasting time and money in the process.

One timber company we have helped, is a family owned business that specialises in timber drying. They design and build kilns and control systems in order to bring automated drying solutions to the timber industry and act as a supplier. Over their 15 years of operation, they have upgraded old kilns and built new ones internationally. Using PLC control and automation technology, a Timber Company is able to improve their customers’ efficiency and reliability.

The timber company often choose to integrate Unitronics PLC+HMI all-in-one controllers into their drying solutions. One unit the often use is the Vision350, a full-function PLC with integrated 3.5-inch touchscreen HMI and onboard I/O. This compact design made it easy to incorporate the Vision350 into larger systems and the all-in-one programming software enables them to program the ladder logic, HMI elements and communications in a single environment, saving time and effort.

In order to control the drying kiln, the Vision350 has thermocouple inputs connected to temperature probes. Using PID functionality, the PLC maintains a steady temperature in the kiln; the PLC can run the drying process automatically based on preset schedules or the operator can adjust setting and runtimes manually from the HMI panel. Digital inputs and relay outputs are used to switch on and off other elements like fans, vents and heaters. The company also configured the Vison350 to communicate wirelessly to the customers SCADA system, enabling it to export data and trends for monitoring and accountability purposes.

Unitronics, have created a product of efficiency, which will control the temperature in the kiln and keep this ongoing without you lifting a finger, from the moment you set up the program. You can purchase this element of efficiency from your local Alldrives & Controls Ltd who are an approved distributor for Unitronics in the UK.
