Woodman spraying automat energy-efficient compensating ventilation
At the Woodman wood processing production facility, we installed an energy-efficient compensating ventilation system for a traverse-equipped automated spraying unit. The solution reuses the energy from the exhaust air of the finishing machine by means of a plate heat exchanger and water-based heating, and pumps the heated clean air back into production. A room pressure sensor keeps the environment in balance by compensating for the vacuum created by the spraying unit. As solvent-based finishing materials are used, the equipment is ATEX-certified.
Fully automatic pallet chain conveyor for timber packages
We designed and built from scratch a fully automatic pallet chain conveyor for handling timber packs for a rapidly growing wood industry company. The system lifts packs with pneumatic paws for buffering, straightens the stack and tracks the position of each pack with an encoder, enabling multiple packs to be stored along the conveyor simultaneously. The lifting force of the paws is 1 tonne and the drive chain speed is 19.82 m/min, and the entire system operates in fully automatic mode with a manual backup mode.
Push-pull welding ventilation for 10 manual welding stations and a separate system for robotic welding
For the metalworking workshop, we designed two separate welding ventilation systems: a push-pull solution for 10 manual welding stations and a separate filter system for the robotic welding area, each with its own airflow rates and control logic. In the manual welding area, welding fumes are directed in a controlled manner towards the central part of the building, with air exchange in the 10-station area ranging between 12,000–18,000 m3/h. A strip curtain limits the spread of fumes outside the work area, and a heat recovery ventilation unit keeps heat loss under control in winter (heat recovery ~80%).
Adding a cooling section to the drying oven for the wood finishing line
On a wood manufacturer's automated finishing line, the components did not cool down sufficiently after exiting the drying oven, which increased the risk of surface defects occurring during packaging. Elister OÜ designed and added to the existing line a specially calculated and customized cooling section that integrates cooling directly into the drying process. The result is fast and efficient cooling of the paint layers and perfectly finished surfaces without damage or defects.
Creating Ventilation for the Blasting Room
For forestry equipment manufacturer Ferrel, we added a standalone filter unit to the existing shot blasting room, which ventilates the room air and cleans it of the dust generated during shot blasting. In this way, a function that is usually incorporated from the outset in new shot blasting rooms was successfully added to an old working environment.
Heat Recovery Ventilation and Air Exchange System
For Lasita Maja's new Makor coating line, we implemented efficient heat recovery and factory air compensation. We installed two units with an air exchange rate of 25,000 m³/h, which, according to our calculations, required no heating section, and completed all overhead air ducting above the ovens. The system operates automatically and monitors the working process using pressure sensors, ensuring trouble-free operation of the line's equipment.
Automated Door Painting Line
Elister designed and installed a fully automated door coating line for Viljandi Aken ja Uks, where every step from loading to packaging is automated, traceable and data-driven. At the core of the solution are two CMA painting robots, RFID-based product identification, Graco dosing systems and a Power & Free conveyor that coordinates the simultaneous movement of up to **500 products**. The robot cycle time is **2 minutes** and every door produced has a digital passport.
UNIFOG humidification system for the school's woodworking department
We installed a UNIFOG humidification system in the wood processing technology department of the Estonian University of Life Sciences, covering a total of 7 zones of varying size and air exchange requirements. In the smallest room, approximately 2.4 m in height, we installed a fan-based atomizer instead of a piping system. For centralized system management, we set up a UNIFOG touchscreen that logs the temperature and humidity of each zone. In addition, we installed a water treatment unit with an iron filter.
UNIFOG pipe humidification modernization in a woodworking plant – 16 zones
For a North Estonian timber industry company, we modernized the entire factory's humidification into a UNIFOG pipe-type humidification system. The system consisted of 16 humidification zones and was one of the largest solutions we have supplied. The control panel was installed in the technicians' room, and the system is practically maintenance-free. The installation took a total of three weeks.
