RWR KST
Descaling and Flushing System for Cooling Ducts
The RWR KST is a specialized descaling and flushing system designed for cleaning cooling ducts in plastic injection moulds and similar tooling systems. Over time, deposits inside cooling channels can reduce cooling efficiency, increase cycle time, and affect process stability.

Why Choose the RWR KST?
Direct Supply & Return Flushing: Simply connect to the mold's existing inlet and outlet. The system circulates specialized cleaning agents deep into the internal channels, removing scale without requiring complex tool dismantling.
Faster Cycle Times & Stable Production: By completely clearing out the cooling ducts, it restores optimal thermal transfer, giving you consistent part quality and faster production runs.
