TLM-3D Software

Product Temperature Visualization during Freeze-Drying

A digital twin of a freeze-drying system visualizes complex process sequences in real-time and time-lapse mode.

Tempris provides the TLM-3D software to develop solutions faster, reduce process transfer time, and maintain quality using data analysis.

Tempris uses the TLM-3D software to support customers with wireless and battery-free sensor technology to scale their processes or for approval processes.

In the future, TLM-3D software, with AI, will offer additional functions and solutions to streamline lyophilization.

Transforming a production machine into a digital twin promotes innovation. 3D data in a digital twin enables better process mapping for the scaling or transfer of lyo products. This leads to improved process optimization and the ability to switch to dynamic processes.

You can easily upgrade your current Tempris software with this application.

Tempris Sensors

The TL sensor model, short for “Temperature measurement lyophilization,” is designed for measuring temperatures in R-vials, H-vials, and injection vials in conjunction with the original stopper. These sensors can also be applied to additional formats such as bulk vials, sealable membrane bags, or even double-chamber cartridges using suitable accessories. Up to 40 sensors can be utilized simultaneously in each run. The TL sensor model comes in five different formats based on packaging materials and filling quantities, with the primary distinguishing factor being the sensor length.
