The OHS Series overhead stirrers are the ideal solution for the most demanding applications: The powerful brushless motor and microprocessor ensure excellent performance and make the VELP OHS Series overhead stirrers unlike any conventional stirrer.
- Premium stirring power to complete any task
- Brushless motor ensures maximum power up to 200 Ncm
- OHS series maintain a constant torque at any speed (up to 2000 rpm)
- Torque indicator to monitor viscosity changes
- Integral timer
- SpeedServo™ counter-reaction technology
- Models with single- and double-speed gears
Torque is stable over the entire speed range, ensuring maximum power even at high speeds. All the models guarantee maximum safety. The robust sealed housing and IP 54 protection rating guarantee long service life even in the most aggressive environments. Integrated safety sensors deactivate stirring in the event of overload, overheating and short circuit, preserving performance over time.
The instrument's ‘Lock’ function prevents inadvertent changes to settings during application. The SmartChuck™ technology simplifies the process of inserting and removing the shaft, which can also be done one-handed and requires no tools. With two simple steps, the protective ring can be unlocked to operate the shaft in and out with ease. Opening the ring during the stirring process will automatically stop the analysis and the instrument will inform you to ensure maximum safety.
OHS series overhead stirrers are easy to use thanks to the smart user interface that shows all the necessary information. In addition, the integrated timer, which can be set from 1 min to 99.59h, allows operation without operator supervision. The OHS Advance models, the most innovative in the range, allow you to control and monitor processes via Wi-Fi connection to VELP Ermes and via USB to your PC.
VELP Ermes allows you to control the devices from your PC, smartphone and tablet via a simple and intuitive web interface. With this platform you can activate stirring, set a timer, set a method (among those saved on the device), download and share reports with one click.
For applications in the pharmaceutical, biotechnology and life science sectors, VELP Ermes can handle OHS Advance located in clean rooms or other controlled environments, without the need for time-consuming security procedures.
