In wood processing, energy costs are one of the largest components of operating costs. Drying processes, heating systems and ventilation consume significant amounts of energy - much of which is emitted directly to the outside environment. Heat recovery solutions allow this energy to be recovered and reused.
Elister on Graco official representative in Estonia - we provide thermal management solutions based on Graco equipment integrated into ventilation and heating systems in wood processing plants. Graco heat recovery systems are reliable, energy efficient and easily integrated into existing systems.
Our heat recovery solutions include:
Elister designs the heat recovery solution according to the size of the production building, the heat sources and the climatic conditions. A correctly sized heat recovery system can reduce heating costs 30-60%, paying for itself within 2-5 years.
How does heat recovery work in a wood processing plant?
The heat recovery system collects heat from the drying processes, ventilation air and production equipment and transfers it back into the space heating or process air. This significantly reduces the fresh energy that would otherwise be used for heating. Graco equipment ensures reliable heat recovery even under harsh production conditions.
What is the payback time of a heat recovery system?
The payback period depends on the size of the production building, the current energy costs and the efficiency of the heat recovery. In most cases, a correctly dimensioned heat recovery system will pay for itself in 2-5 years. Elister carries out a cost-benefit assessment before starting the project.
Is heat recovery also suitable for an existing ventilation system?
Yes - heat recovery can be added to an existing ventilation system by means of heat exchangers and accessories. Elister assesses the suitability of the existing system and offers an optimal retrofit solution based on Graco equipment.
The powder coating process uses high-temperature furnaces, which inevitably emit large amounts of heat to the outside environment.
With our help, it is possible to find different ways to recycle this energy.
Our compressor heat recovery system is an innovative solution that allows you to make maximum and highly efficient use of the heat energy generated by your compressor. The compressor generates approximately 80% of heat energy in its operating cycle, which is normally dissipated through the cooling radiator. Our system reverses this approach by directing the valuable thermal energy to a heat recovery unit instead. During the compressor's operation, the oil in the screw system heats up to 120°C. This is the heat recovery process. Our unit uses [...]
