Table Top Steam Sterilizer (Pre & Post Vacuum Facility)
Table Top Steam Sterilizer (Pre & Post Vacuum Facility)
Model: NSW-234

“NSW” pleased to introduce table top steam sterilizer for today’s growing demand for more sophisticated sterilization technologies. Any private or dental clinic can enjoy the benefit of this technology right in their office. Outpatient clinics, which have increased significantly in recent years, perform highly skilled invasive surgery on their own premises. They rely on advanced sterilization technology. In addition, the increasing tendency towards modular space design in the clinic makes our pre & post vacuum tabletop autoclaves the perfect solution.


This autoclave is made of complete stainless steel 304 Qlty having outer & inner wall & has capacity of 22 liters chamber has compact outer dimensions making it a perfect fit for today’s contemporary clinic. There is mineral wool insulation between the two walls .Designed to sterilize class B cycles. A common application is in the medical or (operating room) as an independent sterilization unit or in dental and private clinics that need to sterilize narrow and hollow instruments and wrapped packs. It has 2 nos. perforated shelves. The water reservoir has capacity of 6 liters of distilled or low quality deionized water. This sterilizer are designed to perform class B cycle that meet the strictest EN 13060 European standards.

 Pre Vacuum Air Removal:

Porous and packed load types as well as fabrics have one thing in common: Air is trapped inside these instruments and fabrics, resulting in air pockets that prevent the full penetration of steam. It is known that spores and bacteria can survive at 134 Deg.C in air pockets.  Therefore, pre vacuum air removal eliminates air pockets from all load types and maximizes steam penetration to instrument components.

Post Vacuum Drying:

When hot steam comes in contact with the cooler instruments, condensation can form. Condensation becomes even more serious with packaged loads, when moisture can remain after the cycle ends. A moist load does not provide sufficient SAL (Sterility Assurance Level). Post vacuum drying provides complete drying of porous loads and hollow instruments at the end of the sterilization process.

Temperature Control:

Temperature shall be controlled by Microprocessed PID Controller which will have following features:

  • Auto purging: Set Temp.
  • Purging Stop: - Set Temp.
  • Auto Exhaust:- Cool
  • Elapse Time
  • Set Temperature:- Could be set
  • Facility for temp. control
  • Auto cycle stop
  • Buzzer at cycle over

Operating Temp. 121 Deg.C to 135 Deg.C
Sterilizing Pressure 1.2 to 2.3 kg /Cm2

Pressure can be achieved upto 760mm/ hg approx.

This sterilizer work on 200/ 220 volts A.C 50 Hz.

Size of Inside working Chamber
Dia 250 x Depth 450 mm

Option:PC connection port for direct PC access enables direct software updates and remote maintenance or data can be collected through USB port.

Horizontal High Pressure Cylindrical Steam Sterilizer
Horizontal High Pressure Cylindrical Steam Sterilizer
Model: NSW-235

Robust and right construction design for all type of bulk sterilization which are commonly required in medical, agriculture and pharmaceutical .  suitable for sterilizing hospital dressing linen , rubber , plastic goods, surgical instruments glass wire etc.

It is based on the principle that any microbiological action of saturated steam elevated temp. in rapid and through.


Triple walled with steam jacket with separate boiler all construction are made up of heavy gauge S.S steel 304 Qlty.  mounted on tubular stainless steel frame with ground leveling screwed flanges. The outer jacket is wrapped with mineral wool to minimize the heat loss.  These sterilizers are hydraulically tested to withstand 2.5 times of working pressure. 

Steam generator is made of heavy gauge stainless steel sheet heavy ring mounted in front of the boiler with folding thick stainless steel plate is fitted with heating element and low water level cut of device to protect with the former from burning out dry.  Pressure control device is fitted in all electrically operated sterilizer.  It cuts of the power supply to heater when the set pressure is activated flange type immersion heating elements are made of high grade material.

Safety Door:

Sterilizer has engaged self-locking single piece thick S.S. plate door and cannot be operated under pressure.  The self locking device automatically disengages the thread mechanism when the sterilizer is under pressure to preclude any eventuality of accident.

Single Point Control:

Complete sterilizing cycle is controlled from on point with the help of “Multiport Valve” fitted at front top.  Two speeds of steam exhaust are available fast and slow.  Easily readable jacket and chamber pressure on gauges mounted on the multiport valve.  A moisture trap is fitted in the chamber discharge  line to absorb the condense automatically to prevent moistening of the subject matter to be sterilized

Safety Features:

The sterilizer is provided with the triple safety features.  At the boiler level by a PIEZOSTAT which automatically limits the pressure to the required set valve and a spring loaded safety valve in case of its failure which releases the steam to keep pressure within the safety limits.  At the chamber level, a spring loaded safety valve and a dead weight release valve to release the steam in case the pressure exceeds the safety limit.  All these safety features function independent of one another failure. 

A plug screen prevents the discharge line form choking.  The plug is easily removable for daily cleaning.  Power ejector for drying sterilized line circulates the air throughout the chamber.  The circulating air passes through a corrosion resistant metallic wool filter.  A steam trap is fitted in the chamber discharge line to eliminate the condensate automatically.  Fully Automatic by PID Controller to show the chamber temperature.  Automatic Vacuum breaker is provided to break vacuum due to steam condensation.
