Key Features
1. Fully Stainless-Steel Double-Wall Construction
The inner chamber, outer chamber, and support ring are constructed from stainless steel. This provides a durable structure and supports easy cleaning and maintenance.
2. Stainless-Steel Chamber & Components
The heater cover stand and carrier/bucket are made from stainless steel. The pressure vessel, external wall, top lid, and basket are also specified as stainless-steel construction.
3. Thick Machined Stainless-Steel Lid
The lid is manufactured from a thick machined stainless-steel plate, providing a strong and durable closure for the sterilization chamber.
4. Radial Locking Lid
The radial locking mechanism provides secure lid closure during pressurized operation and is designed with operator safety in mind.
5. Multiple Safety Systems
The OPX-229 incorporates several pressure and safety devices, including:
- Pressure gauge
- Spring-loaded safety valve
- Double safety valve
- Manual exhaust valve
- Vacuum breaker
- Water-level indicator
- Miniature circuit breaker
These systems provide multiple layers of operational and electrical protection.
6. Jointless Silicone Rubber Gasket
A molded jointless silicone rubber gasket provides sealing between the lid and chamber.
7. Argon Arc Welded Internal Joints
All internal joints are argon arc welded, ground, and polished to create smooth, crevice-free internal surfaces that are easier to clean.
8. Easy Chamber Cleaning
A dedicated drain valve facilitates convenient draining of water and cleaning of the chamber after operation.
9. Energy-Efficient Heating
Industrial-grade energy-efficient heaters are used to provide the required heat for steam generation while helping reduce power consumption during operation.
10. Electrical Protection
A miniature circuit breaker (MCB) is provided for mains ON/OFF control and additional protection of the electrical control system.
Sterilization & Pressure System
The OPX-229 is designed for steam sterilization at a specified sterilizing condition of:
- Sterilizing Pressure: 20 psi
- Sterilizing Temperature: 121°C
- Operating Pressure: 15–20 psi
- Exhaust: Manual through exhaust valve
- Pressure Monitoring: Stainless-steel pressure gauge
- Pressure Safety: Spring-loaded and double safety valve arrangement
- Vacuum Protection: Vacuum breaker
Specification note: The supplied information states “Sterilizing, 20 psi) at 121°C.” For website publication, this has been interpreted as 20 psi at 121°C.
Safety Features
The Vertical Square Autoclave OPX-229 incorporates multiple safety provisions for pressurized steam operation:
Pressure Gauge
Allows the operator to monitor chamber pressure.
Spring-Loaded Safety Valve
Provides pressure relief if pressure exceeds the intended operating condition.
Double Safety Valve
Provides an additional pressure-safety arrangement.
Vacuum Breaker
Helps prevent unwanted vacuum conditions within the chamber.
Manual Exhaust Valve
Allows controlled manual release of exhaust/steam.
Water-Level Indicator
Helps monitor the available water level for steam generation.
Miniature Circuit Breaker
Provides electrical protection and mains ON/OFF control.
Radial Locking Lid
Provides secure mechanical locking of the lid during operation.
