H.P.H.V. Steam Sterilisers
This technique uses mechanical air removal with the help of a vacuum pump (water or oil seal or water jet ejector) & offers several advantages overstandard sterilization cycle.
• Near 100% air removal from the sterilization chamber.
• Better temperature uniformity in the chamber because of the absence of air pockets which result in cold spots.
• Good penetration of steam in porous products from which removal of air is difficult.
• Vacuum drying at the end of the sterilization hold period ensures drying of the material which has been sterilized.

Rapid Cooling Sterilisers
Standard / HPHV Steam Sterilization suffers from several disadvantages when processing glass ampoules bottles or PVC pouches
• Product is cooled naturally. Hence cooling is slow.
• Steam cannot be exhausted rapidly to achieve,faster production rates.Fast exhaust can cause pressure imbalance between the container and the chamber which will ultimately destroy the load.
• Slow cooling will have disasterous effectwhen sterilizing heat labile medications.
• Standard steam sterilization fails to provide necessary counter-pressure tor sterilization of PVC Pouches.

Leak Testing Systems
Glass ampoules are susceptible to damange which may accur during manufacture, filling or handling i.e. cracks in the glass ampoule. AIRPAC now offers the Pharmaceutical Industry two systems which will simply identify defective ampoules during visual inspection.

Vacuum Test For Cracked Ampoules
This test consists of vacuum exposure following the steam sterilization phase.
Defective, cracked ampoules will burst or leak when exposed to vacuum, due to high pressure differential over the ampoule glass wall.

Dye Test For Cracked Ampoules
This test consists of filling the sterilizer chamber with water, to which a speciality dye is added to a level above the ampoule load.The chamber is then pressurized to force some of the dye solution into any defective or cracked ampoule. The chamber is then drained of the dye water

The Chamber
The Sterilization Chamber is usually double walled - a inner S.S. 316 chamber and an outer Carbon Steel or S.S. 304 Jacket. The jacket in addition to improving the temperature uniformity in the sterilization zone also reinforces the chamber. Various features have now been incoroorated to imorove oroduct value.
• The sterilization chambers are provided with a sloping bottom to ensure complete condensate removal from the system.
• Adequately sized condensate line for rapid condensate removal for faster cycle time and better temperature uniformity.
• Special reinforcement pattern for jacket-chamber thereby eliminating any direct welding of Carbon Steel with the inner chamber.
• Special welding technique for welding of nozzles / connectors thereby eliminating all depressions and bubbles.

AIRPAC now offers the user a choice of two door designs
• the conventional radial arm door.
• Or fully-automatic sliding doors.
• Both doors are provided with safety features which prevent
• Simultaneous opening of both doors.
• Opening of the door when the process is on.
• Sliding doors however offers several advantages over Radial Arm type of doors:
• Insulted door surface which improves temperature uniformity in the chamber..
• Completely automatic opening and closing of the doors.
• Better utilization of chamber space.
• Improved gasket life.
• Bettersealing undervacuum.
• More positive safety features.
All models are available with single or double door design.
