Pilot Freeze Dryers by Zirbus are high-quality systems engineered for laboratory and product development. Offered by Apex Scientific in South Africa, these reliable lyophilizers are ideal for pilot-scale research and pre-production testing. With ice capacities ranging from 5 to 40 kg, they meet a variety of freeze-drying requirements while maintaining a compact footprint of up to 2.7 m².

 

Designed for Laboratory Versatility

These Pilot Freeze Dryers include a standard vacuum valve for precise control and a separating valve that maintains a clear barrier between the condenser and the drying chamber. This setup ensures consistent results and greater process efficiency. Whether you’re testing new formulations or scaling up, the design supports smooth transitions between applications.

 

Robust and Hygienic Build

Constructed entirely from stainless steel, these units are resistant to all common disinfectants. Their durable build is well-suited for demanding laboratory environments that require frequent cleaning and long-term reliability.

 

Compact Yet Powerful

Despite their strong performance, these freeze dryers maintain a space-efficient design. This balance makes them ideal for research facilities with limited lab space but a need for scalable freeze-drying capability.

CIP (cleaning in place)

Spray nozzles mounted in the chamber and condenser ensure intensive cleaning
 

SIP (sterilization in place) (from sublimator 15)

Chamber and condenser are designed as pressure vessels, so that steam sterilisation in place is possible. Alternatively, H2O2 is also possible.
 

GMP-FDA compliant

Taking the guidelines into account, the systems meet the highest demands for production in compliance with cleanroom standards. The exact requirements are defined and implemented together with you.
 

Liquid-tempered shelves made of stainless steel

For an even and rapid temperature distribution, the shelves are flooded with brine oil.
 

Closure device for vials

The shelves can be automatically moved together after the drying process to seal vials under vacuum conditions. The optimal preservation.
 

Air or water-cooled refrigeration system

Depending on the installation site, we can design the refrigeration systems to be air-cooled or water-cooled.
 

Wall mounting (gas-tight)

The front of the unit is installed gas-tight in a wall. This allows the service area to be separated from the production area.
 

Oil-sealed and oil-free vacuum pump

If organic solvents are present, it may be useful to use an oil-free vacuum pump.
 

Insulator- Glovebox coupling

The units can be connected to insulators via a connecting flange. Special designs are also possible.
 

Versch. Control systems, SCADA visualisation

We offer a variety of different visualisation and documentation systems.
 

EX-protection version ATEX, solvent discharge

If explosive gas mixtures are present, the systems can be equipped with explosion protection.
