VELP OHS Overhead Stirrers
The VELP OHS Series are professional overhead stirrers engineered to deliver powerful, precise mixing across a wide range of volumes and viscosities. Available in eight variants across two product lines, Digital and Advance, the series covers maximum torque outputs from 20 to 200 Ncm and volumes up to 100 L, making it adaptable to virtually any mixing challenge from low-viscosity aqueous solutions to high-viscosity materials like molasses and asphalt. Every model in the series is built around a brushless DC motor with SpeedServo™ technology for consistent speed under changing load conditions, an IP 54 sealed case for corrosion resistance in aggressive environments, and the exclusive SmartChuck™ system for tool-free shaft changes with one hand. The Advance line adds a 3.5" TFT graphic display, programmable methods, real-time torque and temperature graphing, a safety vibration sensor, Pt 100 temperature probe, and Wi-Fi connectivity to the VELP Ermes Cloud Platform, making it the choice for the most demanding lab applications. Designed and manufactured in Italy, the OHS Series sets the standard for safety, reliability, and performance in overhead stirring.
