Maintenance and Preventative Service Protocols
The complexity of freeze-drying equipment necessitates a robust preventative maintenance schedule to avoid costly downtime and the loss of sensitive materials.
Technical services focus on the health of the vacuum pumps, the integrity of the hydraulic shelf-ram systems, and the detection of leaks in the refrigeration circuits. Helium leak testing is a common service used to identify microscopic breaches in the chamber or condenser that could compromise the vacuum. Additionally, the heat transfer fluid must be periodically tested for degradation or contamination, as any change in its thermal properties can lead to uneven drying across the shelves. Proper maintenance ensures the longevity of the equipment and the safety of the products being processed.
