CO₂-neutral heating solution for EOL Vent Mining
EOL Vent Mining and VEAB Heat Tech collaborate on sustainable mine ventilation
In a joint project, EOL Vent Mining and VEAB Heat Tech have delivered a complete electric heating solution to Norwegian mining company Rana Gruber. With the aim of reducing CO₂ emissions, old propane heaters have been replaced by a turnkey electrical system with 440 kW electric heaters – an important milestone in the mine's sustainability journey.
A common goal: sustainable and demand-controlled ventilation
EOL Vent Mining AB specialises in ventilation solutions for the global mining industry – from fans to demand-controlled systems. The company's goal is to deliver the right amount of air to the right place at the right time, with the lowest possible energy consumption.
To achieve this goal, EOL only works with suppliers who meet high standards of quality and environmental responsibility. VEAB Heat Tech AB was therefore a natural choice. Thanks to its energy-efficient solutions and strong environmental focus, VEAB Heat Tech AB is now a key supplier of heating and cooling systems for EOL's projects.
Rana Gruber: from propane to electricity
In 2023, a major project was carried out for Rana Gruber in Norway, where EOL Vent Mining – in close collaboration with VEAB – designed, delivered, installed and commissioned a CO₂-neutral heating system for heating intake air in the mine.
The solution consists of two prefabricated electrical substations that supply eight 440 kW electric heaters with energy. The system replaced previous propane heaters and is a major step towards reducing the mine's climate impact.
Inside each electrical substation there are three sections:
- Medium voltage: 20 kV switchgear with possibility for future expansion
- Transformer: Converts 20 kV to 400 V
- Low voltage: 400 V switchgear with heater control and automation
The heaters are automatically controlled and adjust the temperature of the intake air according to current needs – which both increases energy efficiency and improves the working environment underground.
A collaboration with a focus on the future
‘For us, it is important to understand the different requirements that each underground mine faces in terms of ventilation. This project shows what we can achieve when we combine our expertise with the customer's needs and the suppliers' solutions,’ says Samuel Anderzén, CEO of EOL Vent Mining.
Both EOL Vent Mining and VEAB Heat Tech are very positive about the continued collaboration. Together, they want to help more mines in the transition to energy-efficient and CO₂-neutral ventilation systems.
