Pressure Vessel Operating Conditions
The central component of the Nova8800 is the precision machined pressure vessel designed to accommodate pressures from sub-critical levels to 2,000 psi and temperatures ranging from ambient to 100°C. The vessel is designed, constructed, and certified to the American Society of Mechanical Engineers (ASME) codes.
Specs of Pressure Vessel
The Nova8800 vessel and head are manufactured from 316 Stainless Steel with vessel dimensions of 16 inches (diameter) by 24.25 inches (deep). The vessel volume is approximately 21 gallons (80 L). The retaining rings are a plated steel alloy and split into 2 symmetrical halves. The vessel head seal is specifically designed to accommodate the pressures and chemicals used in all NovaSterilis processes. The system is designed to accommodate hundreds of leak-proof operations.
The stirring system is programmed to operate at a broad range of speeds to meet the application requirements. The system is designed to automatically re-engage the stirrer in the event it senses disengagement to ensure uninterrupted operation.
Internal operating temperatures are monitored directly in real-time. The real-time temperature is displayed on the touch screen monitor whenever the system power is on. Heaters maintain temperatures as measured by the unit’s thermocouple across a broad range of operating temperatures. The heaters are programmed to avoid operation below approximately 10°C unless specially programmed and can operate in the full on, full off or percent on modes for maximum operating flexibility.
Vessel pressure is monitored through redundant pressure sensors to ensure the validity of the pressure. The current vessel pressure is displayed on the touch screen monitor whenever the system’s power is on. The pressure monitoring system is accurate to better than 1% of expected operating range.
The unit utilizes a single board computer containing all of the necessary embedded software and data storage for several thousand runs. The board provides connections for the following standard and optional peripheral equipment:
- LCD Touch Panel Monitor
- Barcode Scanner
- PC Keyboard
- Network connections
Optimal Ambient Conditions
The Nova8800 is designed to be installed indoors in a well-ventilated area. Ambient air conditions should remain between 59 to 86°F (15 to 30°C) and relative humidity is not expected to exceed 80% (non-condensing). Acceptable geographic altitudes are from 0 to 6,550 feet (0 to 2000 meters).

|Depth||41”||> 36” from wall||77”|
The installed unit weighs approximately 2,200 pounds. The weight is distributed over 4 legs and wheels.
Electrical Service Requirements
The Nova 8800 is manufactured with plugs for standard receptacles for the following circuits:
- One (1) – 120 volt, 60 Hz, Minimum 15A circuit
- One (1) – 240 volt, 60 Hz, Minimum 50A circuit
Pneumatic System Supply Requirements
Compressed air is used to operate the pneumatic system. Compressed nitrogen may be substituted if necessary. The source should be filtered and the filter should be located immediately upstream of the unit.
Carbon Dioxide Supply
A reliable source of CO2 is critical for proper operation of the NovaSterilis equipment and processes. Temperatures for CO2 storage should be such that the CO2remains in a liquid state. Tanks shall be of the siphon type. Alternative CO2 supply configurations should be reviewed with NovaSterilis prior to implementation. NovaSterilis support services are available to arrange for CO2 supply.
The customer’s facility shall install a means to adequately vent the CO2. Never attempt to operate the unit without adequate CO2 exhaust venting.
Preventive Maintenance should be performed by an authorized NovaSterilis service technician under a NovaSterilis factory service contract (details available upon request).
