Description
ASA RS- HTS
Pulley with integrated hydraulic
Torsion vibration damper
The new RS-HTS, introduced in Q4/2025, replaces our K05/K07 radial centrifugal clutches, which have proven themselves for decades. When disengaged, the RS-HTS establishes a permanent power connection – while still damping rotational irregularities, especially in the near-idle range. The result: smooth operation in an ultra-compact design.
What makes it better
-
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.
-
Standard with 8 PK grooves => suitable for most vehicles with 6/7/8 PK poly - V belt drive
