SERVICE
CONSULTATION
Mr. Geser has been working in the field of drilling and geothermal energy since 1979 and has a very large and extensive wealth of experience. Let us advise you and thus benefit from this enormous expertise.
SERVICES
EWS plants
- Site instruction during drilling and extension of the EWS
- Probe extension – clean and durable connection of PE pipes by welding sleeves (Frialong)
- Filling of the system with glycol and propylene
Camera inspection for geothermal probes
In case of probe leakages, it is now possible to inspect the individual pipes of the geothermal probes with DA32, DA40, DA50 and larger up to a depth of 350m and significantly improved image quality by endoscopy using a special camera and record them simultaneously.
Possible damaged areas are precisely localized with parallel running depth measurement. Based on the damage pattern, conclusions can be drawn about possible causes of the failure.
Waterjet cutting machine
A Mach 3b with dynamic-waterjet, a cutting pressure of 4150 bar and a working area of 2 x 4 m enables us to respond even better and more flexible to the wishes of our customers. Besides the already known preventer seals we are now able to offer wellhead seals as well as special seals in different designs and best quality. We are also able to cut almost all other materials such as steel, marble, stone, glass, composites etc. in an optimal way that is gentle to the material.
A selection of our products, which are made with the water jet machine, you can find here.
