Horizontal Cylindrical Autoclave

The chamber is oriented horizontally with a front-loading door, enabling effortless loading and unloading of large-volume or bulky loads. This setup supports the use of wheeled carts, reduces operator strain, and improves workflow efficiency compared with top-loading vertical models, making it practical for laboratories, hospitals, pharmaceutical plants, and industrial settings.

Units are available in single-door or double-door configurations. Double-door models support continuous workflow and sterile-area separation (pass-through design), allowing materials to move from a non-sterile loading side to a sterile unloading side while maintaining barrier integrity.

Chamber diameters generally range from 400 mm to 700 mm, with depths from 600 mm to 1300 mm, providing volumes typically between 79 and 500 liters. This range accommodates everything from laboratory-scale loads to industrial batches of bulky instruments or bulk media.

The autoclave operates in the 121°C–134°C temperature range (adjustable) at standard pressures around 0.22 MPa (approximately 15–30 psi). Typical hold times are 15–30 minutes at 121°C or 3–5 minutes at 134°C, ensuring complete microbial destruction through saturated steam.

A validated multi-phase cycle includes: air removal (via vacuum or gravity displacement), pressurization and heating with saturated steam, sterilization hold at the set temperature and pressure, vacuum-assisted drying to remove residual moisture, and controlled cooling/depressurization with door interlocks for operator safety. Digital controllers and sensors provide real-time monitoring and data logging.

A jacketed vessel improves heat-transfer efficiency, helps maintain uniform temperature, and reduces overall cycle times. Combined with strategically placed steam ports, it ensures consistent steam distribution throughout the chamber for reliable sterilization results.

Modern models feature automatic pressure and temperature control via digital or PLC-based panels with programmable cycles and real-time monitoring. An integrated vacuum pump enables efficient air removal for superior penetration into porous loads. Optional printer or USB connectivity supports complete cycle documentation for regulatory compliance and audits.

Safety interlocks prevent the door from opening under pressure. Additional protections include pressure relief valves, overheat protection, alarms, and robust stainless-steel construction. These features help prevent accidents and ensure safe operation during high-pressure cycles.

It is widely used in the pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries, as well as in hospitals, laboratories, research facilities, and industrial settings. Key benefits include large chamber capacity for bulk loads, uniform steam distribution, efficient vacuum-assisted drying, reduced cycle times via jacketed design, easy-to-clean smooth interiors, and long-term corrosion resistance from stainless-steel construction.
