See OverShield in Action
The liquid line solenoid valve in the low-stage compressor system stopped operating, causing the high-stage system to work in overdrive to compensate for the malfunction. Maintenance staff was unaware of the issue because the chamber temperature remained in specifications.
Neither situation came to fruition because OverShield protected the chamber. The team was lucky to have OverShield because this failure would not have been caught by traditional maintenance practices or GMP monitoring.
In this situation, the cost was $200 for a replacement valve, which took an hour to install. Without OverShield, the consequences and costs would have been extensive.
