Horizontal Rectangular Steam Sterilizer

With innovative high-performance sterilizing technology, Lodha autoclave chamber is made of AISI 316L stainless steel and entirely covered by a high efficiency jacket to ensure fast heating and reduced cycle times. This ensures even heat distribution and reduced utilities consumption for heating and cooling. Chamber design minimizes dead space for optimal loading and throughput. The LI-RA models are specially designed for steam sterilization of surgical instruments, textiles, clothes, rubber items, metal, plastic and glassware. They are used in hospitals, including CSSD, operating rooms.

Features:

  • Single and double door pass through options
  • Technical service access either on the left or right loading side

Working programs:

  • Process cycles according to EN 285 are factory programmed
  • and available for the operator to select via the touch screen
  • control panel.
  • Standard programme cycles include: 121°C and 134°C for textiles, medical instruments & rubber etc.
  • Additional programs are available such as a Prion cycle or can be programmed and validated according to customer
  • specifications.
  • Temperature inside the chamber is uniformly distributed with a temperature deviation of less than 0.5°C.
  • The touch screen displays cycle status and alarms with cycle data stored on the PLC and available from the integrated printer.
  • 6 factory pre-programmed cycles.

Test/service programs

Vacuum Leak Test: this cycle is used to verify the vacuum integrity of the sterilizer
Bowie-Dick Test: this cycle is used to verify the effectiveness of steam penetration and air removal

Horizontal Rectangular Steam Sterilizer FAQs


It uses pressurized saturated steam to eliminate microbial contamination and is widely used in pharma, Ayurvedic, and cosmetic facilities for safe and efficient sterilization of equipment and materials.

Yes — it sterilizes herbal raw materials, vessels, and packaging components while maintaining GMP hygiene standards.

Yes — cosmetic manufacturers sterilize mixing tanks, filling equipment, and containers to prevent spoilage and contamination.

The rectangular chamber provides greater usable loading space, ideal for trolleys, trays, and bulky equipment.

It operates at 121°C to 134°C and 15–30 PSI, meeting global sterilization standards.

It includes validated cycle controls, temperature sensors, and data logging essential for regulatory audits.

Instruments, glassware, garments, rubber stoppers, herbal materials, cosmetic tools, and liquid-filled containers.

Yes — pharma-grade models provide validation ports and thermometric data logging support.

Available from 100 liters to 5000+ liters with custom sizes for different production scales.

Yes — PLC touchscreen controls, automatic door locks, and pre-programmed cycles ensure safe operation.

A typical cycle lasts 45–90 minutes depending on load size and selected temperature.

Yes — slow exhaust cycles allow safe sterilization of liquid herbal decoctions without overflow or breakage.

The inner chamber is SS 316L and the outer jacket is SS 304 — both pharma-grade materials.

Yes — pass-through models create a sterile barrier between dirty and clean zones in controlled environments.

After sterilization, a vacuum-assisted drying cycle removes residual moisture from wrapped or porous loads. This ensures instruments, garments, and components come out completely dry and ready for immediate use or transfer into cleanroom areas.

Yes — it is designed as per Schedule M (Revised), WHO-GMP, CE norms, and ASME pressure vessel codes, making it audit-ready for Indian and international regulatory inspections.

Manufacturers typically provide installation support, operator training, calibration services, validation assistance, spare parts supply, and Annual Maintenance Contracts (AMC) to ensure long-term validated performance.

It includes multiple safety layers such as a pressure relief valve, pressure gauge with alarm, door interlock system that prevents opening under pressure, and emergency stop controls for complete operator protection.

Yes — chamber dimensions, number of trays or trolleys, pass-through configuration, steam source (self-generating or plant steam), and PLC control systems can be customized to match specific facility layouts and production needs.

By processing large batches efficiently, reducing contamination-related rejections, and ensuring smooth regulatory audits, most pharma and cosmetic companies recover their investment within 12–24 months of consistent operation.
