What is the temperature control precision of Bocon's heating system?

Our systems are engineered for high-precision thermal stability, typically achieving a temperature uniformity of ±1°C or better within the chamber. This is managed via high-performance Siemens PLC controllers and redundant RTD sensors to meet the strict requirements of ISO 11135.

How does Bocon handle safety in explosive EtO environments?

Safety is paramount as EtO is highly flammable. Bocon utilizes ATEX or IECEx-certified explosion-proof fans and heating elements. The system includes an automated nitrogen purging cycle and real-time monitoring of gas concentrations to ensure the heating process only occurs under safe, non-explosive conditions.

Can the Hot Air System be integrated with existing SCADA systems?

Yes. Our control architecture is built on industrial standards (typically Siemens or Allen-Bradley). We provide full integration capabilities with factory-level SCADA or MES systems, allowing for automated data logging, audit trails, and compliance with 21 CFR Part 11 for electronic records.

Q: Why is high-velocity air circulation critical for EtO sterilization?

EtO sterilization depends on the 'Big Four' parameters: Gas concentration, Humidity, Time, and Temperature. Bocon's Hot Air System ensures that heat and moisture are distributed uniformly throughout the entire chamber load, eliminating cold spots and ensuring that the EtO gas can penetrate medical devices effectively, regardless of their position in the chamber.

Advanced Air-Jacketed Heating Technology

One of Bocon’s core engineering breakthroughs is our signature Air-Jacketed Heating System. Unlike traditional hot water jacket designs, Bocon utilizes a sophisticated hot air circulation system to maintain chamber temperature. This innovative approach offers a superior alternative to conventional systems, delivering significant advantages in operational safety, thermal precision, and long-term maintenance efficiency. By choosing air over water, we provide our clients with a cleaner, more reliable, and energy-efficient sterilization environment.

1. Vacuum Pump Technology

Item	BOCON	OTHERS
Vacuum Pump Options	Dry Screw / Water Ring / Oil Ring (Multiple options available)	Usually only Water Ring Pump
Ultimate Vacuum Level	Up to -101.27 kPa (Dry Screw Pump)	Approx. -90 kPa
Water Consumption	With BOCON Gas-water separator: Water replaced once per week	Continuous water consumption
Maintenance	Low maintenance (Dry pump), No oil emulsification risk	Frequent oil change (Oil pump) or limited performance

2. Water-Saving Performance

Example: A 5.5 kW water ring pump consumes approximately 20 liters per minute. For a 20m³ sterilizer chamber with 8 vacuum cycles (22 minutes each), total water consumption per cycle reaches 3.52 tons.

With 14 cycles per week, total weekly consumption exceeds 49 tons. After installing BOCON’s exclusive Gas-water separator system, water replacement is required only once per week, saving approximately 45 tons of water per week (approx. 180 tons per month). This is especially valuable in water-scarce regions.

Technical FAQ

Expert insights into Bocon EtO Sterilization Hot Air Circulation Systems

EtO sterilization depends on the "Big Four" parameters: Gas concentration, Humidity, Time, and Temperature. Bocon's Hot Air System ensures that heat and moisture are distributed uniformly throughout the entire chamber load. This high-efficiency circulation eliminates cold spots and ensures that the EtO gas can penetrate dense medical device packaging effectively, regardless of their position in the sterilization chamber.

Our systems are engineered for high-precision thermal stability. We typically achieve a temperature uniformity of ±1°C or better within the chamber volume. This level of control is managed via advanced Siemens PLC controllers and high-accuracy RTD sensors, ensuring the process remains within the validated range required by ISO 11135 standards.

Since EtO is highly flammable and explosive, Bocon utilizes ATEX or IECEx-certified explosion-proof fans and specialized heating elements. The hardware is designed to prevent spark generation. Furthermore, the system is interlocked with the control software to ensure that the heating process only operates when gas concentrations are within safe levels, often involving nitrogen dilution as a safety cushion.

Absolutely. We provide modular solutions ranging from 1m³ laboratory units to 100m³ large-scale industrial chambers. We calculate the required thermal load and air exchange rates based on your specific product density and chamber volume to ensure optimal performance for your sterilization cycles.

To maintain medical-grade cleanliness and resist corrosion from sterilization gases, Bocon uses high-quality SS304 or SS316L stainless steel for all internal ducting, fan blades, and chamber surfaces. This ensures longevity and prevents any particulate contamination of the medical devices being processed.

Yes. All Bocon systems are equipped with advanced data acquisition capabilities. Every parameter—including temperature, pressure, and fan speed—is recorded in real-time. Our software is designed to be compliant with FDA 21 CFR Part 11, providing the electronic records and audit trails necessary for international regulatory inspections.
