The Rhytemper® HotPulse is a multi-circuit temperature control system that precisely regulates the heat removal of each individual temperature zone in the injection mold. Temperature and flow are continuously monitored and controlled, ensuring consistently high product quality and shortest possible cycle times.
ONI Rhytemper® HotPulse
Multi-Circuit Pulse Temperature Control for High-Temperature Injection Molding
Customer installation example – mold-proximate setup enables precise heat removal

Accessories
ONI RHYTEMPER Temperatur Control Units
The high-performance temperature control units from ONI Temperiertechnik RHYTEMPER® GmbH are ideal for use as stand-alone systems or, even more efficiently, in combination with an ONI temperature control installation.
ONI Rhytemper® Mold Drainage System
ONI temperature control systems come with perfectly matched accessories. Blow-out units are used for the effective emptying of cooling channels in injection molds before a mold change. This process reliably protects the cooling channels from corrosion during storage.
Filter unit
Perfectly matched accessories are available for ONI tempering systems. Filter units help prevent tool contamination and system malfunctions caused by dirt or metallic deposits from the cooling water network, ensuring reliable and sustainable operation.
