Triple-Wall Construction
The OPX-234 is designed with a triple-wall body structure to provide mechanical strength and improve thermal insulation around the sterilization chamber.
The three-layer construction helps reduce heat transfer to the external surface while supporting stable operation during high-pressure steam sterilization.
Radial Locking System
The autoclave uses a radial locking mechanism designed to provide secure closure of the chamber during operation.
The locking arrangement works with the pressure-control and self-locking systems to help prevent unsafe opening while the chamber is under pressure.
Stainless Steel Construction
The major pressure-containing and structural components are manufactured using SS 304 grade stainless steel.
Stainless Steel Components
- Pressure Vessel – SS 304 Grade Stainless Steel
- External Wall – SS 304 Grade Stainless Steel
- Top Lid – SS 304 Grade Stainless Steel
- Tubular Stand & Supporting Ring – SS 304 Grade Stainless Steel
- Basket – High-Grade Stainless Steel
The stainless-steel construction provides durability and makes the equipment suitable for demanding laboratory and institutional environments.
High-Pressure Sterilization
The OPX-234 is designed for high-pressure steam sterilization in the range of:
- Sterilizing Pressure: 1.2–2.5 kgf/cm²
- Operating Pressure: 15–35 psi
- Sterilization Temperature: 121°C–134°C
The combination of controlled pressure and temperature enables the system to provide steam-based sterilization for suitable heat- and moisture-resistant materials.
Pressure & Exhaust System
The exhaust pressure is manually controlled through the exhaust valve. A multiport valve is included for managing the relevant sterilization-cycle functions.
The system is also equipped with a pressure gauge for monitoring chamber pressure during operation.
Note: Your supplied specification states the pressure gauge as “0.2.1 kgf/cm² (60 psi),” which appears to contain a formatting/typing error. For the website, I would recommend confirming the exact gauge range from the manufacturer’s datasheet before publishing that specific figure.
Automatic Pressure Control & Safety
The OPX-234 incorporates several control and safety features designed for high-pressure steam operation.
Included Safety & Control Features
Automatic Pressure Cut-Off Switch:
Helps control the system when the preset pressure condition is reached.
Automatic Low-Water Cut-Off:
Helps protect the heating system when the water level becomes insufficient.
Automatic Self-Locking System:
Provides secure locking of the chamber during pressurized operation.
Water-Level Indicator:
Allows the operator to monitor the available water level.
Digital Temperature Indicator Cum Controller:
Provides digital monitoring and control of the sterilization temperature.
Moisture Trap
A moisture trap is included to help manage condensate generated during the sterilization process.
This is particularly useful for applications where excessive moisture in the sterilized load should be minimized.
Jointless Silicone Rubber Gasket
The chamber is fitted with a jointless silicone rubber gasket designed to provide a reliable sealing interface between the chamber and lid.
A proper gasket seal is essential for maintaining pressure and minimizing steam leakage during operation.
Stainless Steel Sterilization Basket
The OPX-234 is supplied with a high-grade stainless-steel basket for placing sterilization materials inside the chamber.
The basket design allows the operator to load and unload materials conveniently while allowing steam to circulate around the load.
Available Chamber Sizes & Capacities
The OPX-234 is available in multiple chamber dimensions to meet different sterilization-volume requirements.
| Dimension (inch) | Inner Dimension (mm) | Capacity | Heater Load |
|---|---|---|---|
| 16 × 24 | 400 × 600 | 78 Litres | 6 kW |
| 16 × 36 | 400 × 900 | 115 Litres | 6 kW |

| 22 × 48 | 550 × 1200 | 300 Litres | 12 kW |
| 24 × 48 | 600 × 1200 | 350 Litres | 12 kW |
Capacity Range
78 L to 350 L
This range allows the OPX-234 to be configured for small and medium-scale laboratory and institutional sterilization requirements.
Optional Fully Automatic Configuration
For users requiring greater automation, the OPX-234 can be supplied with optional automatic control systems.
1. Fully Automatic PID Purging System
A fully automatic PID-based purging system can be provided for controlled and automated air-removal/purging operation.
2. HMI & PLC-Based Fully Automatic System
A fully automatic HMI/PLC-based autoclave control system can be installed on order.
The optional system can include:
- HMI control interface
