ASP Sterrad 50
ASP · Model Sterrad 50
Increased speed and capacity • Rapid 45-minute cycle time. • 1.55 cubic foot rectangular chamber holds multiple trays. • Dry, low-temperature process means instruments are available for immediate use or storage. • Reduces expensive instrument inventories. Unsurpassed material compatibility • Compatible with most medical devices. • Tested by 250 device manufacturers on over 1,500 devices. Reduced instrument damage and repairs • Gentler than steam and peracetic acid processes. • No corrosion due to humidity. • Reduced damage due to heat, shock, and handling. Easy to install and move • No water source, heat booster, or ventilation required. • Runs on standard 110-VAC to 120-VAC, 60-Hz electrical. • Compact and portable.
Key tips
- ·A failed biological indicator means the entire load is not sterile - no exceptions, regardless of how the cycle printout looks.
- ·Door gasket wear is the most common real cause of a failed vacuum/pressure test - check it before deeper diagnostics.
- ·Water quality directly affects steam-cycle validity - don't ignore scale or mineral buildup.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Door gasket / seal leak
HighSymptoms: Pressure loss, long cycle, gas leak alarm.
Root cause: Aged rubber gasket.
Sterilant cartridge / cassette fault
HighSymptoms: Cycle abort, low-sterilant alarm.
Root cause: Empty, expired, or misread cartridge.
Vacuum pump failure
MediumSymptoms: Poor air removal, cycle abort on vacuum draw.
Root cause: Worn vanes/seals.
Chamber temperature sensor drift
MediumSymptoms: Temp out of tolerance, failed cycle indicator.
Root cause: Sensor aging.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily biological and chemical indicator test loads
- ·Door gasket / seal inspection
- ·Steam trap and drain strainer cleaning
- ·Annual full PM and pressure-vessel certification
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Door gasket / seal leak
- Confirm the presentation - typically pressure loss, long cycle, gas leak alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: aged rubber gasket.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the door gasket / seal per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
