SALIENT FEATURES OF ESTEEM AUTOCLAVE
I. Autoclave will be in sturdy construction using plates of appropriate thickness which prevents buckling under vacuum or bulging due to pressure. Made to confirm to EN 285 or HTM 2010 performance requirements.
II. Fully automatic by means of PLC based controls, which operate pneumatically actuated solenoid valves. Provision of four different cycles and programs :

1. Standard cycle
1a. Heat up – ster hold (1210 C) – exhaust
1b. Heat up – ster hold (1340 C) – exhaust

Suitable for standard and custom sterilisation cycles at 134 °C and 121 °C, with pre-vacuum, conditioning/sterilisation and post-vacuum/drying phases.
The technique uses the method of gravity air removal to ensure uniform steam distribution and penetration.
Steam trap equipped with air vent ensure maximum air removal.
Useful for sterilization of glass containers i.e. ampoules, vials, glass bottles etc.
It is also useful for Sterilization of glass wares, utensils, vessels, instruments, rubber articles linen etc.
in Laboratories and hospital.

2. HP HV cycle
2a. 3 pre ster vacuum pulses – heat up – ster hold – exhaust
2b. 3 pre ster vacuum pulses – heat up – ster hold – exhaust – post ster vacuum pulsing for drying

Preset cycles, including at least for instruments (134 °C), textiles (134 °C), mixed load (121 °C and/or 134 °C), heavy load (134°C), prions (134 °C) plastic/rubber (121 °C), liquids (121 °C and/or 134 °C), glassware (121 °C and/or 134 °C), fast cycle (134 °C), Bowie-Dick test, vacuum and self test.

This technique uses near 100% air removal from sterilization chamber which results in better temperature uniformity in the chamber because of the absence of air pockets i.e. cold spots. This technique increases the penetration of steam in porous products from which removal of air is difficult.
Vacuum drying at the end of sterilization hold period ensures drying of the material which has been sterilized.
This cycle is useful for garments, fabrics, drying rubber bungs vessels machine parts etc.

3. Leak Test Cycle for periodic testing of door integrity and pipeline connections & detecting leakage ampoules.
4. Another HP HV cycle with post vacuum pulses can be provided, if required, for special purpose

  • SS construction with internal contact parts of SS 316.
  • SS construction with Jacket parts of SS 316.
  • The unit is mounted on sturdy SS tubular stand with level adjustment facility.
  • The jacket volume is comparatively large (depth of 50 mm) which ensures better heat distribution in
  • No drives are required. For sliding door movement, pneumatic cylinders are used.
  • Autoclaves with hinged doors have mechanical pressure locking device which prevents opening of doors under pressure. The quick throw lever mechanism ensures further safety.
  • Door interlocking provision prevents opening of doors under pressure as well as opening of both doors at the same time – after sterilizing cycle only Aseptic side door can be opened. Besides this interlocking, an visual indication is also provided.
  • The unit has two safety valves, on the chamber and one on the Jacket, besides having a pressure switch which shuts off steam supply to the chamber.
  • PLC’s used are Imported and compatible with P C. SCADA system can be incorporated for remote monitoring OR monitoring, controlling and data acquisition if required (Optional).
  • External communication RS232
  • Continuous monitoring of temperature and pressure
