One door manufacturer in Central Estonia decided to take its finishing process to a whole new level. The aim was to introduce an automated finishing solution, but at the same time to create a modern manual finishing area - because in quality door manufacturing, you simply can't do without manual finishing.
Automatic finishing solution chosen MAKOR SPRAY & DRY - M a compact spraying system well suited to the needs of door production, allowing a stable and high quality finish.
The manual finishing booth was completely solved by our Elister team, designing and building the solution according to the production needs of the factory and the working logic of the existing automated line.
At the heart of the finishing solution were GRACO PerformAA series automatic paint spray guns with Merkur series pumps.
The whole system had to be designed, installed and put into operation exactly during the factory's collective holiday. This meant that there was virtually no room for error - every day and every stage had to run according to plan.
In addition, the ventilation was directly connected to the Makor system. The solution detects which device is currently running and adjusts the ventilation modes accordingly.
The result is an energy-efficient, safe and well-functioning finishing environment, which supports production efficiency at every step.
MAKOR SPRAY & DRY - M compact spraying system ensures precise colour application and a stable finish. GRACO PerformAA automatic paint spray guns with Merkur series pumps ensure accurate paint application and reliable operation even in intensive production.
The ventilation was connected directly to the Makori system. The solution recognises which unit is running at any given time - whether it is an automatic finishing line or a manual finishing booth - and adjusts the ventilation modes accordingly.
The result is an energy-efficient system where the ventilation works exactly as much as needed.
The automatic finishing line ensures high productivity in batch production. The manual finishing booth, on the other hand, allows flexibility for special shapes, one-offs or small batches. Together they form a complete finishing solution.
The Graco Perform AA automatic spray gun is a high pressure automatic spray gun designed for production lines and robotic painting systems. PerformAA technology ensures precise air nozzle orientation and uniform Fine-Finish coating.
Paint booths are at the heart of a manufacturing plant's finishing process - it is their quality that determines the appearance of the final product, the safety of workers and the energy consumption. Elister designs and delivers paint booths both for the finishing of individual products and for the production of finished products.
PERFECT TECHNOLOGY. BEST RESULT. With a wide choice of pump sets, there is a pump to suit everyone's needs.

MAKOR SPRAY & DRY - M is a compact and automatic spraying system that ensures a precise and even application of paint without manual operators. The system incorporates automatic door handling with LIFT loading/unloading device and works with 4 spray guns and a 2 L paint tank. Energy-saving automation allows the ventilation to be adapted to the actual load.
GRACO PerformAA series automatic paint spray guns with Merkur series pumps ensure accurate paint consumption and reliable operation even in intensive production. The spray guns are compatible with a wide range of paint materials and are suitable for both aqueous and solvent-based lacquers and paint products.
The ventilation is directly connected to the MAKOR SPRAY & DRY system via automation. The system detects the mode in which the finishing line is currently operating - either the automatic spray line or the manual finishing booth - and adjusts the ventilation mode accordingly. The result is an energy-efficient system where the ventilation runs exactly as needed.
The manual finishing booth allows flexibility to handle special shapes, one-offs or small batches that cannot be handled efficiently on an automatic line. Elister's team designed and built the booth in-house, ensuring optimal LED lighting, ventilation and safety. Together with the automated line, they form a complete finishing solution.
Lower Explosive Limit (LEL) detectors continuously measure the concentration of volatile organic compounds (VOCs) in the air and warn when concentrations approach dangerous levels. Compressed air monitoring ensures that the guns receive a constant pressure, which has a direct impact on paint quality. Both systems are integrated into the overall automation of the finishing line.
A detailed timetable was drawn up for the implementation of the project during the factory's collective holiday, with each stage precisely planned. As production was at a standstill, the Elister team was able to carry out all the work without disruption and to install the equipment in several locations simultaneously. With the support of a precise design and an experienced team, all the equipment was installed, tested and commissioned on time.

Big projects often start with small questions. And so it is this time. In May 2025, a chance conversation revealed that Viljandi Aken ja Uks had been looking for a solution for a new paint line for some time, but had not found a final partner. A simple question: „Why haven't you asked us?“. opened the door - Elister was given the opportunity to submit its offer, which proved to be suitable for the client's needs and led to a deal.
The summer was spent planning and designing, after which the practical work began around Christmas - preparing the site and dismantling the old systems and installing the new line. From that moment, the idea became a reality.
For Elister OÜ, this was the first project of this scale where the entire responsibility - design, procurement coordination, logistics and execution - was entirely on the shoulders of one partner.
A fully automated door paint line where every step - from loading to packaging - is automated, traceable and data-driven.
An all-in-one solution that combines quality, speed, flexibility and full traceability:
Loading and conveyor: vacuum lifters for safe door hanging and a Power & Free conveyor that coordinates up to 500 product movements simultaneously.
RFID product identification: each door is equipped with an RFID sticker that allows the system to know the location, colour and recipe of the product at any moment. Separate low-frequency chips are used on the booms to avoid signal mixing.
Automatic cleaning: de-ionisation, compressed air purification and aspiration - the unit automatically adapts to the dimensions of each door.
Colouring books: three Graco Duro-Flo pumps for base materials and Merkur series pumps for speciality materials. Two special colour pumps for each robot - cycle time 2 minutes.
Painting robots: two CMA robots working independently - simultaneously with different shades and substances. Four Graco ProMix 3KS 3-component mixing systems (2 for robots + 2 for hand booths).
Flash-off, drying, after-buffer: controlled solvent evaporation, drying tunnel up to +60 °C (air circulation up to 60 000 m³/h) and uniform cooling before packaging.
Automation and data: four Siemens HMI control panels, a mobile tablet, cameras and information screens. Each door produced has a digital passport.
Safety: ATEX Directive requirements, solvent, temperature and humidity sensors in the control circuit and STS fire detection system in the paint booths.

The client's production process required stable temperatures in both the paint and drying rooms. To ensure this, a boiler was used continuously, including during the summer.
At the same time, the compressors were running at high daily load, but their residual heat was not being used.
Energy savings of around 800 kWh per day.
The solution significantly reduced the boiler load, lowered energy costs and improved the energy efficiency of the whole system.
We installed a heat recovery system for two compressors (55 kW and 37 kW), which transfers the waste heat generated to heat the production processes.
The solution was integrated into the existing system, reducing the need for a high capacity boiler.
Heat management solutions are not limited to the installation of the appliance. Each production process is different and to achieve maximum effect, the solution must be integrated into the existing heating system.
Our strength lies in our ability to design and implement a complete solution - from the selection of the right equipment to its integration into an existing system, or, if required, as a custom solution.
This makes it possible to maximise the use of all the waste heat generated and achieve significantly higher energy savings than a standard solution alone.
We'll do a quick calculation based on your compressors and heating system - you'll immediately see the potential energy savings, payback time and CO₂ impact.

Static electricity can be a real headache when working with wood surfaces. This project required a solution to a situation where, at work, range of charge up to an impressive 12.3 kV in places, making the process uncomfortable for employees – every touch acted as a small „grounding“ device. This situation was neither safe nor effective.
To solve the problem, we installed two iONstream 4.0 neutralization device – for one lower surface and another upper surface. The result after the equipment was put into use was 400-750V between.
iONstream 4.0 is a unique device equipped with a microprocessor that automatically detects the polarity of the charge and adjusts its operation accordingly.
This solution ensures that excess charge is removed from products as efficiently as possible and that employees are provided with safe and stable working environment.

The client wanted a comprehensive overview of their production aspiration solution. All the equipment was connected behind a single filter, which was causing low air velocity in several workstations and consequent problems in the production process. The piping was being built out gradually as new equipment was added and there was no project documentation reflecting the actual situation. The aim was to map the whole system, check the air velocities, calculate the air requirements and distribute the equipment between the two filters to ensure a reliable and efficient aspiration solution.
A comprehensive set of documents is handed over to the client, including a detailed piping diagram, measured air velocities and any other data required for future use.
In the course of the project, we drew the entire aspiration piping with the necessary calculations. A large number of old lines were removed and replaced with new piping that was in line with the design. Unnecessary penetrations were closed and the equipment was distributed between the two filters according to their importance. Following the installation work, measurements were carried out to check that the system was in accordance with the design.

Our goal was to design and implement a solution that would remove the fine dust generated by the chipper directly from the place where it is generated. The need was to reduce cleaning/maintenance requirements and keep the room dust-free.
We took advantage of the customer's existing aspiration filter, and designed a new aspiration pipework and a hood above the machine. On the cube we used removable fins.
In order to ensure that the machine is also accessible for maintenance work, the cube was placed on a rack, which allows it to be moved and ensures easy access.
In addition, we installed an extraction nozzle in the room, which allows the fine dust to be directed directly into the existing filter during cleaning.

Nordwood is a common trademark of three sawmills - AS Viiratsi Saeveski, AS Viru-Nigula Saeveski and AS Aegviidu Puit - combining high quality sawn timber produced from Nordic pine and spruce logs. Nordwood's products are used both in Estonia and in export markets in the construction industry and as raw materials in the furniture, packaging and timber industries.
Cool production space and permanently open doors
Elister received a request from Nordwood in autumn 2024, when there was a problem with cool working conditions in one of its production units. The specific nature of the production building - constantly open doors - made finding an effective heating solution a challenge. The wind tunnel created by the open doors resulted in a high heat loss and maintaining the working temperature proved difficult.
To solve the problem, we installed three industrial water-heated air curtains from Metmann in Nordwood's production building. These units are capable of circulating up to 25 000 m³/h of air in the room, providing uniform heat and reducing the inflow of cold air through open doors. The solution not only improved working conditions but also reduced energy consumption while keeping the room at a comfortable temperature.
