Frövi Greenery is a unique technical project with sustainability at its core. As part of the electrical installation, we installed all pumps and control systems on behalf of KUBO. This setup allows Frövi to make full use of the excess heat from the paper factory. It ensures the heating system can use this residual heat effectively. 

We connected all systems and installed 18 control panels. These manage the greenhouse departments, heating, and AVS units. We also installed additional panels for the lighting systems. The technical integration allows everything to work together, ensuring the systems stay up and running at all times. 

Remco explains: “One major challenge was laying the underground cables on the rocky terrain. We even had to use dynamite to make space.” Despite the difficult conditions, the team created a detailed digging plan and worked closely with other teams. That ensured perfect alignment for all lines and cables—whether for CO₂, heating, electricity, or water. This strong collaboration made the project a success, even under tough conditions. 

The system in the greenhouse consists of three heat sources: the paper factory, two heat pumps, and a bio-oil boiler. These sources can operate independently or together, optimizing sustainability at all times. The integrated heat system also includes frost protection and snow-melting capabilities, ensuring uninterrupted operations in Sweden's cold winters. 

“By working closely with KUBO and the customer, we overcame the challenges and delivered a fully integrated system,” Remco says. The result is a greenhouse that runs smoothly under all conditions and supports sustainable horticulture. This project highlights the importance of collaboration, precision, and adaptability. At Royal Brinkman Technical Projects, we’re proud to have made a valuable contribution to this innovative and sustainable solution. 

Water technology
The advanced water system filters lake water using reverse osmosis. An automatic flushing system ensures a constant supply of clean water and nutrients for the plants.

Climate control
We installed Hoogendoorn’s advanced IIVO system, which monitors everything from temperature to humidity. The system can be remotely managed by the grower to ensure optimal growing conditions.

Commissioned by KUBO
Together with KUBO, we tackled the challenges of this project with a shared focus on quality. Through strong collaboration, we contributed to an innovative, sustainable, and future-proof greenhouse setup.
