Technical FAQ

Q1: What maintenance is required for the vacuum pump?
A:The oil-free scroll pump requires:

• Annual bearing lubrication (Grease NLGI #2).

• Bi-annual diaphragm inspection (wear limit: 0.2 mm thickness).
  No oil changes needed, reducing long-term operational costs.

Q2: Can the PLC interface with legacy manufacturing systems?
A:Yes, the system supports:

• 4-20 mA analog I/Ofor basic integration.

• Modbus RTU/TCPprotocol conversion modules.

• Custom driver development for proprietary PLC networks.

Q3: How is temperature uniformity maintained in large batches?
A:The oven uses:

• 8-zone resistive heatingwith independent PID control.

• Turbo-assisted airflow(3 m/s velocity) for heat distribution.

• Real-time thermal mappingvia 12 internal PT100 sensors.

Q4: What safety protocols prevent solvent ignition during vacuum drying?
A:Optional ATEX-rated models include:

• Inert gas injection(N/CO) during venting.

• Spark-resistant fan blades(aluminum-magnesium alloy).

• Exhaust gas dilutionto <25% LEL (Lower Explosive Limit).

Q5: What customization options are available for shelving?
A:Configurations include:

• Rotating racksfor uniform powder drying (max. 200 RPM).

• ESD-safe trays(surface resistance 1010 ) for electronics.

• Perforated shelveswith 3 mm/5 mm/10 mm aperture options.

Q6: How does the oven handle volatile organic compounds (VOCs)?
A:Integrated abatement systems:

1. Primary Condenser: Captures 90% VOCs at -25C.

2. Activated Carbon Filter: Absorbs residual solvents (99.5% efficiency).

3. Catalytic Oxidizer: Optional for full VOC mineralization (EPA Method 25A compliant).

Q7: What data logging capabilities are included?
A:The system provides:

• 21 CFR Part 11-compliant logswith digital signatures.

• CSV/PDF reportswith timestamps and operator IDs.

• Predictive maintenance alertsbased on vibration/thermal analytics.
