On behalf of the investor, Arctic Green Engineering Services Ltd. (formerly Mannvit Ltd.), under an EPCM (Engineering, Procurement Construction Management) contract, assisted in the construction of a 3 MW geothermal heating system in Szentlőrinc. After geological research and analysis to establish the geothermal energy recovery, we prepared the licensing and design plans for the system, carried out the necessary licensing procedures, then, with the involvement of the investor, we carried out the procurement procedures for the main equipment and selected the contractors to construct the system. We managed and technically supervised the works, ensuring a permanent presence on site during the construction. After the system was completed, our specialists were involved in the commissioning, setting up the operating parameters with the operators and fine-tuning the operation.
