Geo Vario 18
Our most powerful device for geothermal drilling - uncompromising performance.
This standardised double-head drilling rig from Nordmeyer has been specially developed for the most demanding geothermal applications. With an impressive retraction force of 18 tonnes, it offers the necessary power reserve for deep drilling in difficult geological conditions - combined with the proven Nordmeyer quality and many years of field experience.
The system is powered by a water-cooled 6-cylinder turbo diesel engine from Volvo® with 210 kW (286 hp), which complies with the latest emission standards in accordance with emission stage V. The use of AdBlue® ensures environmentally friendly and future-proof operation. A newly developed combination cooler for hydraulics, engine and charge air ensures consistently reliable performance, even during intensive continuous use. Despite the high output, the sound pressure level remains reduced - for a more pleasant working environment.
The machine is operated via the tried-and-tested N-Drill multifunction control unit, equipped with an ergonomic rotary control, precise joystick and clearly laid out keypad. This is supported by a modern 12-inch colour display with high contrast, which is easy to read even in direct sunlight - for maximum operating comfort and efficiency in daily use.
An integrated Palfinger® PK 12.501 loading crane on the operator's platform rounds off the powerhouse. With a reach of 9.8 m and a lifting capacity of 1000 kg at full extension, it offers additional flexibility when handling drill rods and material - ideal for smooth processes on the construction site.
