Designing Applications

The Vikumer pharmaceutical lyophilizers are cost effective freeze drying solutions, which can be addressed to all pharmaceutical lyophilization applications. Include both injectable formulation freeze drying and bulk material freeze drying.

Offer standard configuration as well as customized accessories and functions. Here is the summary of our standard machines.

Machinery Structure

Drying Chamber and Door

Pressure vessel rated rectangular shape drying chamber. Stainless steel 316L made and surface mirror polished. Inner corners are rounded for easy cleaning.

Hinged door is fully Insulated, with viewing port. Door decoration panel for clean room mount is stainless steel 304 made.

External Condenser

Both condenser chamber and condensing coils are S/S316L made, surface mirror polished. Condenser bottom is sloped for water easy draining.

Isolate of the condenser is a butterfly valve, pneumatically operated.

Shelves and Trays

Flexible shelf module, hydraulic stoppering device. All plates are mirror polished roughness better than 0.6um, flatness better than 0.5mm/m.


Condenser and drying chamber connect can be vertical or horizontal. Drying chamber is rectangular, condenser chamber can be cylindrical or rectangular shape.

System Specifications

Vacuum System

The vacuum pumps installed in pharmaceutical freeze dry system is 2-stage oil sealed pumps and roots pump combination.

Each vacuum pump has individual isolation valve, and is pneumatically operated. Capable of automatic close once electric interrupt.

Refrigeration System
