The LYONOVA® solid-state microwave-assisted lab-scale freeze dryer enables significantly faster lyophilization while preserving product quality.
It allows direct comparison of conventional and microwave-assisted freeze-drying cycles on the same system — making it ideal for product development, feasibility studies and technology evaluation before scale-up.
Why choose LYONOVA®?
Up to 60–80% shorter drying times
Microwave-assisted energy input significantly accelerates the drying phase, depending on the product.
Homogeneous drying without rotation
Dynamic microwave field control eliminates the need for a turntable while ensuring uniform energy distribution.
Freeze and dry in one chamber
Temperature-controlled shelf enables in-chamber freezing and drying.
True A/B comparison
Run conventional freeze drying and microwave-assisted cycles on the same machine under comparable conditions.
Bridge to continuous processing
Chamber design corresponds to a segment of a tunnel concept, supporting future micro-continuous lyophilization.
Test before you invest
Products can be evaluated in dedicated GEA labs prior to equipment purchase.
Microwave-assisted lyophilization — controlled and reproducible
LYONOVA® uses two 250 W solid-state microwave sources, each connected to an individually controlled antenna.
Independent frequency and phase control (2.4–2.5 GHz) allows the electromagnetic field inside the chamber to be actively shaped and dynamically varied over time.
This continuously changing field pattern:
- ensures uniform, volumetric heating of the frozen product
- reduces the risk of local overheating or cold spots
- maintains full control of product temperature
Unlike conventional systems that rely mainly on conductive heat transfer from the shelf, microwave-assisted freeze drying enables faster and more efficient energy delivery throughout the product cake.
Fully functional one-shelf freeze dryer
LYONOVA® is not a microwave add-on but a complete laboratory freeze dryer:
- One temperature-controlled product shelf (–60 °C to +60 °C)
- Shelf size 400 × 270 mm, compatible with standard GORE® LYOGUARD® freeze-drying trays
- Operation as: conventional freeze dryer, or microwave-assisted freeze dryer with additional energy input
This dual-mode design enables reliable process development and technology evaluation.
Process Control & PAT Module
To support robust process understanding, LYONOVA® integrates advanced monitoring options:
- Infrared camera for real-time surface temperature visualization and early detection of hot or cold spots
- Fiber optic product temperature sensors (optional). Suitable for microwave environments and ideal for dynamic process adjustment
These tools support documentation, risk assessment and quality assurance in R&D settings.

The water equation
Across Europe, drought is a recurring reality – and no longer confined to the south. While water increasingly shapes where industries locate, its value is determined by local context. There are many technological routes to water efficiency in industrial processes, but location, energy needs and other factors are also key.
