Factory Air Compensation and Heat Energy Recovery in the Woodworking Industry

We supplied a woodworking company with an ATEX-rated ventilation unit with an air volume of 24,000 m3/h, which serves the existing MAKOR oven and recovers thermal energy by means of a plate heat exchanger. The unit compensates the factory air and ensures a better indoor climate in production. As the oven operates in two modes, pressure control was added to manage both the oven operating mode and the internal production conditions.

Factory Air Compensation and Heat Energy Recovery in the Woodworking Industry

Project Challenge

The existing MAKOR oven operates in two modes, which made air exchange control complex. It was necessary to ensure a better indoor climate in production while also recovering the heat energy exiting the oven. In addition, ATEX requirements and fluctuations in humidity levels had to be taken into account.

How We Built the Solution

We supplied a ventilation unit with a plate heat exchanger that enables efficient heat recovery. The unit was designed in ATEX configuration and adapted to serve the two operating modes of the MAKOR oven.

  • Ventilation unit with an air volume of 24 000 m3/h
  • Plate heat exchanger for heat recovery
  • ATEX configuration
  • Two operating modes of the MAKOR oven: 16 000 m3/h and, in case of excessive humidity, an additional 8000 m3/h
  • Pressure control for managing the oven operating mode and the internal production conditions

Result

The solution compensates the factory air and ensures a better indoor climate in production. Pressure control allows monitoring of both the oven operating mode and the internal production conditions, while the plate heat exchanger recovers heat energy.

FAQ

Frequently asked questions

What is the air capacity of the installed ventilation unit?
The ventilation unit has an air capacity of 24 000 m3/h. The unit was designed in ATEX configuration.
How is the heat energy from the oven recovered?
Heat energy recovery is achieved with a plate heat exchanger in the ventilation unit, enabling efficient heat energy reuse.
How does the solution handle the MAKOR oven's two operating modes?
The unit was adapted to serve the oven's two modes: 16 000 m3/h and an additional 8000 m3/h when humidity is too high. Pressure control manages the oven mode and internal production conditions.
Does the solution comply with ATEX requirements?
Yes, the ventilation unit was designed in ATEX configuration, also accounting for fluctuations in humidity levels.
What benefit does the solution provide for the production indoor climate?

Compressor heat recovery in industry – energy savings of up to 800 kWh per day

At an industrial enterprise, we installed a heat recovery system on two compressors (55 kW and 37 kW) that directs the resulting waste heat to heating production processes. The solution was integrated into the existing heating system and significantly reduced the boiler's operating load. The result was energy savings of approximately 800 kWh per day and improved overall system energy efficiency.

Heat recovery ventilation for paint hall in Karksi

For the timber workshop's new production building, we designed and installed a ventilation system based on a plate heat exchanger with automatic pressure control. The system recovers thermal energy generated during the painting process, compensates for vacuum, and removes moisture originating from the autoclave. Thanks to this solution, the company can continue using its existing boiler without the heat load exceeding the boiler's capacity.
