When operating mining and tunnelling machinery in the mining sector, the heat generated underground must be efficiently transported to the surface and released into the atmosphere. We devise and install the appropriate solution, tailoring it to suit the onsite conditions and fine-tuning it to meet the specific requirements of our customers. Our compact air refrigeration equipment, which travels with the tunnelling machinery, is highly effective, low-maintenance and easy to repair.
