HTS pulley

Quiet operation: Smooth power flow, no gearbox rattle in the near-idle range.  

Effective damping: Integrated hydraulic torsion vibration damper filters torque fluctuations and reliably prevents gear backlash noise in the compressor.  

Ultra-compact: Pulleys are possible from an outer diameter of 80 mm – ideal for tight installation spaces.  

Permanent power transmission: No disengagement at low speed – the torque transmission remains.  

Lightweight & low inertia: Intelligent lightweight construction made of steel and aluminum – minimized inertia (rotatory and translational ) , fast start-up dynamics, low weight.  

Simple service: Should increased noise levels occur after long operating times, simply replace 2 O-rings , 4 silicone dampers and some special oil with our affordable maintenance package – that's it.
