ROTOTEC ACCELERATES THE GREEN TRANSITION
Carbon neutrality is a globally accepted goal to minimise the negative effects of climate change, in which energy production plays a key role. The current military crisis in Europe is a reminder that nations should also strive for maximal energy self-sufficiency. Geothermal energy provides one promising, cost-effective path toward achieving both goals.
In Finland, the growth of geo-energy has been rapid in recent years. One of the key actors in the sector is Rototec, Europe’s largest geo-energy company with more than 60,000 energy wells drilled. Founded in 2007, Rototec has grown strongly in Finland and operates also in Sweden and Norway.
While geothermal energy has long been a popular energy source for single-family houses, Rototec is focusing more on supplying geo-energy for large properties such as hospitals, shopping centres, and factories.
A geothermal system requires one or more bore wells, drilled to a depth of 150–250 metres, depending on the amount of energy required. Robit has been supplying Rototec with drilling tools since the early years of the company.
“Robit, as a big domestic manufacturer, was a natural choice for us. 99% of the holes we drill are four-inch wells and Robit has a comprehensive line of tools for that. Currently, all our drill bits are from Robit,” says Hannu Puolitaival, Technical Director at Rototec.
The fruitful, mutually beneficial cooperation spans back more than a decade and focuses on customer-oriented service.
“Over the years, we have worked closely together to develop drill bits to better meet our needs. We test the products, and share our experience and comments with Robit for further development. One of Robit’s assets is their agility: after our feedback, they can produce new, improved prototypes at a fast pace for testing. Of course, the fact that they have domestic manufacturing helps too,” Hannu says.
“Another strength is that Robit can make small batches. If we’d need, say, five units of a particular new drill bit for testing, that poses no problem. Not all manufacturers can do this,” says Hannu, and adds one more thing: “I have especially liked the fact that Robit has a dedicated person managing all communication with us. It makes our cooperation seamless and straightforward.”
