Harviker OÜ is a furniture manufacturer based on Estonian capital, specialising in birch-based products with a young team. During production, the products are finished on three different finishing machines, which involve considerable volumes of air that are channelled outdoors, creating a large vacuum in the factory. The return air, in turn, needs to be heated.
Increasing green thinking and rising energy prices are the reasons for investments in various heat recovery systems.
On one of Harviker's spray lines, we installed a heat recovery ventilation unit, where the function of the unit is to capture and use the heat energy from the exhaust air (both from the finishing machine and the drying oven). In this project, we use the energy to pre-heat the air that is blown in.
To ensure that the system works automatically, the automation monitors the amount of air being expelled and the vacuum in the plant using pressure sensors.
As part of this project, we also helped the client to install a previously procured drying kiln for the finishing line, where we were responsible for the installation of the equipment and the installation and connection of the heating water piping.
