Sami Production is an Estonian mechanical engineering company with over 30 years of experience in manufacturing road maintenance equipment such as snow ploughs, sanders and brushes. The company's products are mainly targeted at the Nordic and European markets.
In the past, we have created ventilation solutions for both manual and robotic welding workstations in Sami Manufacturing's Sauga factory. Positive cooperation experience and the reliability of the solutions provided the basis for the next step - the Valga plant upgrade.
At the Valga plant, the ventilation of the manual welding workplaces had to be solved in two areas, each with 10 workplaces. We installed a Gram Clean Air equipment - cyclone filters with fans - and we designed the push-pull ventilation system. We also made the corresponding air calculationsto ensure that the system operates correctly and efficiently.
In addition, we integrated automation solution, which analyses the activity of welders and triggers the filter system only when welding is actually taking place. This ensures energy savings and a clean working environment.
As a result, the client received a modern, compliant and reliable ventilation solution that helps to keep the working environment clean and the working conditions for welders safe and comfortable.
In addition to manual welding, we also helped the new robotic welding solution by finding the right welding filter, which also ensures a clean environment in the robotic welding area.

The customer has four welding stations in its production facility where welding fumes are generated during the welding process. All the welding locations are usually working simultaneously and at the same time it was important to maintain the accessibility of the torch throughout the welding area.
We have planned a single PUSH/PULL a ventilation system that allows the removal of fumes and gases without disturbing the production process.
To filter the air, we installed a reliable Danish manufacturer GRAM FL filter unit, which is Plug & Play solution - quick to install and ready to use.
The solution ensures controlled air movement and effective cleaning of welding fumes throughout the working area.

AQ Lasertool OÜ is a company belonging to the Swedish AQ Group, which has 5 factories in Estonia, two of which are located in Pärnu, two in Jüri and one in Viimsi.
There was a constant demand for heating in production and the compressor was running daily - the residual heat from the 55 kW unit was previously unused. Cost-benefit calculations showed that the heat transfer to the heating system of the building would provide a very fast return on investment, so it was decided to implement the solution.
We channel heat energy into both domestic hot water and heating water. All parameters are adjustable.
We installed an automatic heat control system in the oil cooling circuit of the compressor, which regulates the temperature of the oil and the domestic hot water by means of four sensors. The system optimises the heat exchange and prevents the compressor from overheating. A built-in heat meter accurately measures the energy returned. The system can be routed to both the domestic hot water and the building heating system.
The amount of energy recovered amounts to 10 MWh per month on average. Expect an even bigger result in the winter months, as the higher temperatures in the heating system allow more efficient heat transfer due to the small temperature difference. The projected annual residual heat input is more than 120 MWh, which means significant savings in heating costs and CO₂ reductions.

Sami Production carried out a major modernisation project, investing nearly EUR 9 million Upgrading and expansion of the Valga plant. One of the key elements of this investment was New automatic powder coating line designed and installed by Elister, which played a key role in optimising the plant's production processes and increasing productivity.
The company's production facilities were previously located in both Saue, Otepää and Valga, but in order to improve production efficiency it was decided to Otepää factory to be closed and production to be concentrated in the town of Valga. This enabled investment in the expansion of the Valga plant and the introduction of modern technological solutions, including a new paint line.
The case was 4000 m² of new construction and a reconstructed area of the same size., which provided the opportunity to integrate state-of-the-art production solutions.
The previous dye line was the "bottleneck" of production, as it did not allow for the dyeing of large products, which limited production capacity and efficiency.
New automatic powder coating line installed removed this obstacle by allowing:
The choice of colour scheme was an important part of the project. Compared to traditional wet painting, powder painting offers several advantages:
The choice was also customer demand, as many customers, especially in Finland, prefer powder-coated products.
Our system not only improves production efficiency, but also reduces environmental impact.. An important part of the system is heat recovery, where the residual heat from the paint line furnace is not wasted, but is used to. for the heating of production halls and welding halls.
Advantages of the system:
Our contribution was not limited to the installation of the paint line. We have previously also helped Sami Produce the development of welding ventilation, robotic welding and manual welding workstations in both Valga and Saue..

When an unexpected fire hit the paint rooms at Konesko's Koeru factory, a major challenge was faced. The production process was severely disrupted and the situation required a quick and efficient solution. Our task was to help the customer to overcome the crisis and to create completely new painting and drying rooms that meet today's requirements and ensure safe and efficient production.
The main objective of the project was to create two functional colour spaces - one for large and heavy products and one for smaller and lighter ones. In addition, the rooms had to be equipped with drying facilities and ensure efficient ventilation, lighting and remote control of equipment. All the equipment had to comply with the requirements for Ex-proofing and the work had to be carried out without interrupting daily production.
How did it all happen?
The work was carried out in two phases. First, we built a painting and drying room for larger products. This room was equipped with a powerful 15,000 m³/h Ex-rated ventilation system, which ensures a constant supply of fresh air and efficient air exchange. For future needs, we also added the possibility to easily integrate a cooling function. The equipment in the room was mounted on a special fire-resistant metal structure, separated from the rest of the production area by fire-resistant walls. All the solutions complied with the requirements for Ex-proofing.
For the processing of larger products, Konesko has added an Ex-ready shelf to the colour room, making it easy and convenient to lift and move products. The drying room has been equipped with an Ex-equipped drying solution, which automatically regulates the fresh air flow by means of solvent sensors, ensuring both operational safety and optimal energy efficiency. Proper Ex-lighting was installed in all rooms to ensure optimum working conditions and to allow for high quality production.
In the second phase, we focused on the creation of a colour room for smaller products with an effective air exchange rate of 10000 m³/h and a drying tunnel. In the smaller colour room, we used modern energy-saving solutions, complying with all possible standards and safety requirements that colour rooms need to meet. In addition, the "Power&Free" conveyor system allowed for a fast movement of the products, while ensuring sufficient drying time, as the products in the drying tunnel are not in continuous movement.
The result: innovation and efficiency!
The resulting solution is not just a solution to a problem - it is an example of how a crisis can be an opportunity for innovation. Modern Ex-proof ventilation, lighting and automation solutions ensure energy efficiency, safety and ease of use. Thanks to solvent sensors and compressed air readers, the system optimises ventilation as needed, saving resources when no active painting is taking place.
This project is proof of how, with smart and thoughtful action, it is possible not only to rebuild but also to improve in difficult circumstances. We are proud to have been able to help Konesko at their critical moment and to create a solution that will support their production for a long time to come.

Markland has provided full services for ships, from the construction of spaces to the installation of piping systems.
The production process produces pipe assemblies and modules suitable for installation in ships, boiler houses, power plants, offshore processing of oil products, etc.
The quality system is constantly being developed in line with requirements.
The task was to equip four adjacent welding booths with an individually controlled ventilation solution, while maintaining postcrane serviceability in each booth. In addition, it was important to reduce energy costs and optimise system operation.
For this project, we used the Danish manufacturer Gram Clean Air's FL series welding filter, which is now one of the most common filters for various solutions and was ideally suited for this project.
Each welding booth was equipped with a stand-alone "push-pull" with a solution. We designed the system based on the following principles:
Individual control - when the welding process is started, the valves of the corresponding welding box are opened. At the end of the welding operation, the operation of the corresponding zone is shut down after the post-weld time has elapsed.
Air exchange control - depending on the number of active workstations, the automation controls the fan speed.
Calculations of airflow rates, velocities and head direction to ensure the most efficient exhaust and correct equipment selection.
By optimising consumption, we ensure reduced maintenance costs and energy efficiency.

Harmet Metall specialises in the manufacture of metal structures. Their production process makes extensive use of metal welding, which in turn produces a huge amount of blue "welding fumes" that fill the production hall.
As the production process used large parts that were manipulated during the work, it was not possible to create a specific point system for smoke extraction. The most sensible approach was therefore to use GramCleanAir a solution for welding filter towers.
After with demo the customer wanted to buy two filter towers for their production to help keep the environment cleaner.
Harmet Metalli and our team worked together to find a suitable solution for removing welding fumes from the production line. The filter towers help to maintain good air quality and ensure a safe and healthy working environment for welding workers.
We are proud to have been part of Harmet Metal's efforts to optimise their production processes and improve the working environment. Our experience and expertise helped them to find an efficient and sustainable solution that meets their needs.
