Nutrunners
Precision torque-controlled nut running tools for heat exchanger flange assembly — consistent, repeatable, and built for the demands of industrial maintenance.
PRECISION TORQUE FOR CRITICAL JOINTS
Proper bolt torque is critical to leak-free heat exchanger assembly. Under-torqued flanges leak; over-torqued fasteners fail. Elliott nutrunners deliver consistent, calibrated torque to every bolt.
Designed for the heat exchanger maintenance environment — rugged construction, easy field operation, and fast cycle times to minimize equipment downtime during scheduled maintenance.
Key Features
- Precise torque output with ±5% repeatability
- Pneumatic and electric drive options
- Wide torque range to suit all flange sizes
- Ergonomic design for reduced operator fatigue
- Audible and tactile clutch shutoff
- Calibration-traceable torque output
Applications
Pneumatic Nutrunners
Air-powered torque wrenches for fast, consistent bolt-up in maintenance environments.
Elliott pneumatic nutrunners use shop air to deliver controlled torque output with a precision clutch shutoff mechanism, ensuring repeatable fastener torque.
Features
- Precision clutch shutoff at set torque
- Fast cycle time for high bolt-count flanges
- Operates on standard shop air supply
- Available in inline and angle-head configurations
- Multiple socket drive sizes available
Configurations
Electric Torque Wrenches
Battery-powered precision torque tools for locations without compressed air.
Elliott electric torque wrenches provide calibrated torque output wherever shop air is unavailable, with digital torque display and programmable shutoff.
Features
- Digital torque display and logging
- Programmable torque shutoff
- No air supply required — fully portable
- Rechargeable lithium battery
- USB data download capability
