Drying kiln project stages: process electrification

In this series of blogs, our experts explain the different stages in a drying kiln project and other important elements in the world of kilns as part of sawmill operations. This time, Veijo Malmi tells about process electrification in drying kilns.

In our previous blog we went through the different stages in mechanical installation. This blog looks at process electrification, which is done partly at the same time as mechanical installation to minimise the time spent on the work.


Most of the mechanics needs to be completed before work can begin on the process electrification stage. Process electrification covers all the mechanical positions, all the equipment that we deliver for our customers’ drying kilns. So we talk about equipment electrification and automation.


“Marking is an important part of connection work.”


Routes and cable pulling, connection and marking work

The equipment room, where the cabling and other work stages happens, is a key place in process electrification. The work stages are clear. The cable racks, troughs and conduits, i.e. cable routing, are the first to be built. Once the routes are ready, the actual cable pulling can begin.


Cable pulling includes thick motor cables, thin instrument and equipment cables as well as various bus and network cables. After cable pulling, it’s time for connection work at the centre and at the actuator end. Marking is also an important part of connection work. Cables are marked with cable markings and the actuators with data plates so that maintenance later knows which actuator is concerned when troubleshooting.


“The customer’s maintenance has the most precise and accurate documentation of the plant.”


Final cleaning and final blueprints

Once process electrification is completed, it’s naturally time for the final clean up. The blueprints are still marked with a red pen to show how things were done to ensure all changes are visible in the final version. This means the customer’s maintenance has the most precise and accurate documentation of the plant.


Our next blog will deal with the automation of and data transmission in Heinola drying kilns. The amount and importance of automation are constantly increasing in drying kilns. Until next time!
