Cylindrical Autoclave

It is widely used in hospitals, laboratories, pharmaceutical manufacturing, and industrial facilities for sterilizing surgical instruments, glassware, liquids, dressings, and other heat- and moisture-stable items. Key industries include pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical manufacturing.

Items are loaded on perforated trays. The automated cycle typically includes water addition, pre-vacuum to remove air, heating to 121–134 °C under pressure (around 15–30 psi / ~0.22 MPa) for 15–30 minutes, post-vacuum drying, exhaust, and cooling. The process mimics an advanced pressure cooker and ensures thorough sterilization followed by safe unloading.

The temperature range is adjustable between 121 °C and 134 °C. Standard operating pressure is approximately 0.22 MPa (roughly 15–30 psi), conditions proven effective for reliable microbial kill.

Chamber diameters range from 400 mm to 700 mm and depths from 600 mm to 1300 mm, giving useful volumes from about 79 liters up to 500 liters. Power configurations (e.g., 9 kW / 380 V, 50 Hz) can be adapted to local voltage requirements.

The unit features a counterbalanced multi-point radial locking mechanism that allows effortless, one-handed hermetic sealing with uniform gasket compression. Additional safety elements include pressure-relief valves, over-pressure protection, low-water cut-offs, hydraulic testing to 2.5× working pressure, and an automated pneumatic pressure-sensing circuit in the door gasket.

A high-density aerospace-grade ceramic-fiber thermal jacket covered by a mirror-polished SS 304 outer shroud keeps external surface temperatures below 45 °C, reduces heat loss to the cleanroom, lowers energy consumption, and improves operator safety during continuous high-temperature cycles.

A high-definition touchscreen PLC provides multi-level access control (biometric or password), tamper-proof data encryption, automated batch reports, paperless audit trails, USB/network export, and real-time remote monitoring. Early-warning diagnostics detect micro-deflations or gasket wear before a cycle is compromised.

An integrated closed-loop cooling and rapid-venting system with a high-efficiency stainless-steel condenser can cut overall cycle time by up to 30 % versus conventional units while capturing and cooling high-purity condensate, reducing water consumption and thermal shock to drain lines.

The chamber is typically triple-walled stainless steel (SS 304) with an inner process chamber, steam jacket, and insulated outer casing. Factory-fitted multi-sensor calibration ports with tri-clamp sanitary caps allow rigorous IQ/OQ thermal mapping without compromising chamber integrity or requiring temporary modifications.
