Freeze Dryer Restoration and Upgrades


A second life for your Freeze Dryer/Lyophilizer 

Revive your Freeze Dryer!

Don’t have the budget to buy a new Lyo? We will take your existing freeze dryer and make it work/look like new, or even better, make it work like today’s equipment. 

Millrock Technology has revived FTS LyoStar as well as Virtis Genesis and Ultra, Usifroid and Hull systems. 

Revival ranges from periodic maintenance to complete control system upgrades. Revival includes replacing vacuum lines to eliminate rubber hoses, replace and upgrade the vacuum sensors from thermocouple style to Pirani and repainting the panels to new condition. 

Periodic Maintenance includes: replacing the chamber and condenser gaskets, cleaning the air cooled condenser and inside the cabinet, changing the vacuum pump oil and testing the system for proper performance.

Control System Upgrades replace the proprietary microprocessor or aging PLC with a Ethernet based PC/PLC, providing the latest in process control and data collection. 21 CFR Part 11 controls are also available. Every 5 years technology changes to the point where old control systems are obsolete and not supported. Upgrade to a full PC/PLC control system at the fraction of the cost of a new system.
