Torque limiting couplings (TLC)

Eliminate system overloads

Designed to withstand the high torque spikes found in mills that use variable frequency drives, Danfoss Airflex Torque Limiting Couplings (TLC) deliver driveline control and protection for these demanding applications. Easy-to-use TLC decreases maintenance costs and downtime with electronic slip detection and automatic resets.

  • Familiar technology - Based on VC clutch design
  • Reduce downtime - Simpler reset than mechanical couplings
  • Productivity - Maximize mill uptime

Danfoss TLC benefits

  • Continuously monitors torque to prevent overload of the motor and damage to costly equipment
  • Resets and restarts instantaneously, ensuring maximum uptime for your operation
  • Increased torque capacity provides downsizing opportunities, potentially reducing your costs
  • Simple design extends wear part life further and delivers long-term durability
  • Low-maintenance solution that is easy to install and operate

Advanced Slip Detection Control

Danfoss Slip Detection Control technology automatically disengages the TLC if slippage is detected between the motor and the pinion. It also detects fast starts and over-programmed starts, reducing equipment downtime and preventing driveline damage.

How it works

  1. TLC engages at 0 RPM and pressurizes to achieve required torque based on a preset air pressure
  2. Danfoss Slip Detection Control monitors the drive system load and immediately disengages TLC when it detects a torque overload
  3. Reset the grinding mill instantly by reapplying the required air pressure—no downtime required
