The DE1power is the entry-level variant of the DE1 series, designed for industrial applications where process reliability, repeatability and ergonomics are essential – without requirements for documentation or torque-angle procedures. It is particularly suited for series bolting operations in production and maintenance environments where high torque levels must be applied reliably and reproducibly.
Process-Reliable Bolting in Pure Torque Mode
The DE1power operates using the conventional torque method.
The integrated motor control compensates for voltage fluctuations and continuously monitors temperature. An automatic shut-off in the event of overheating protects both the tool and the operator.
With a repeatability of ≤ 4% (depending on the joint condition), consistent quality in series applications is ensured.
Bolting using the torque method
Robust entry-level tool of the highest quality, offering the essential functions for daily use
Designed for Continuous Operation up to 8,000 Nm
Depending on the model size, the DE1power covers a torque range from 150 to 8,000 Nm.
The optimized gearbox is designed for continuous load and is engineered to be:
-
slimmer
-
shorter
-
lighter
As a result, the tool is also ideally suited for repetitive bolting operations in confined installation spaces.
Ergonomics for Series Applications
In repetitive bolting operations, ergonomics are a key factor in efficiency and operator strain:
-
Low-vibration technology
-
360° swivel joint to minimize reaction forces
-
Suitable for both right- and left-handed operation
-
Easy handling, even when wearing gloves
-
Multifunction display showing all relevant joint parameters
These features reduce physical strain during extended periods of operation.
Focus: Speed and Reliability
The DE1power is deliberately reduced to the essentials:
-
No data management
-
No torque-angle functionality
-
No wireless interface
This makes it particularly suitable for companies requiring a robust solution for high-volume bolting applications.
For applications involving documentation requirements, the DE1docu is available as an alternative.
