Product Description

Horizontal Rectangular Single/ Double Autoclave


HORIZONTAL RECTANGULAR AUTOCLAVE is based on the principle that microbiological action of saturated steam at elevated temp is rapid and thorough. All models work on downward displacement of air principle which is most economical method of obtaining for all types of bulk sterilization which are commonly needed in Medical, Agricultural, Research Institute, Pharmaceutical. Suitable for sterilizing hospital dressings, rubber plastic goods, surgical instruments, glass wares etc.


Robust and rugged all weld construction which is leak proof unlike riveted construction. Inner chamber is made of thick plate of Mild Steel of non magnetic stainless steel of 304/ 316 quality and jacket is made out of rolled steel. Sterilizers will have single door made out of rolled steel lined with S.S. 304 sheet on both sides. All the sterilizers are hydraulically tested to withstand 2.Skg/ cm' times the working pressure. The steam jacket is lined on the outer side with asbestos sheet or glass wool which prevents heat losses due to radiation and is covered by 55 304 Sheet.

Boiler Steam Generator

Made of thick stainless steel plate suitably located under the sterilizer. High grade flanged type heating elements are fitted from front side for easy replacement/repair. Fitted with water gauge glass for water level, safety valve, water inlet and drain valves. It is also provided with Low Water Level cut off device. This device protects the heater in the generator from burning out dry. The steam pressure in the boiler is indicated on an individual pressure gauge.

Door Safety Lock

Every National Horizontal Rectangular Autoclave is fitted with SELF LOCKING SAFETY DOOR which cannot be opened when the chamber is under pressure. The clutch mechanism automatically disengages the threads of the radial locking system for precluding any eventuality of accident when the chamber is under pressure. A heat resistant Neoprene Rubber gasket ensure steam tight fitting.

Pressure Control

Electrically operated "PIEZOSTAT" (Pressure Control Device) is incorporated in all electrically operated sterilizers. It economies power consumption and limits the use of release valve which would frequently blow steam into the room. It cuts off the power supply to heaters when the set pressure is achieved and re-energize heaters when pressure falls down.


Complete sterilizing cycle is controlled from one point with the help of "Multi port valve "fitted at front top.

Two speeds of exhaust are available for evacuating.

The Chamber

Two separate valves provided for evacuating air and steam from inner chamber and jacket as and when desired. A steam trap is fitted in the chamber discharge line to eliminate the condensate automatically.

Control Panel Switch Box

To provide electrical control panel box and mounted on the stand of the sterilizer for easy operation.

Electrical parts - pressure switch, contactor, water level relay, MCB, RYB Indicators, & on-off switch.

Safety Features

(a) Special provision prevents the operator from opening the door in following events:-

1. When the chamber is under pressure

2. When one door is open the other cannot be opened (for Sterilizer with 2 Doors).

(b) The sterilizer is provided with triple safety.

1. Pressure control switch which automatically cuts off the pressure at required set value.

2. Three spring loaded safety valves one each at chamber, jacket and boiler level.

3. A dead weight safety valve at chamber level.

(c) A plug screen prevents the discharge line from choking. The plug is easily removable for routine cleaning.

(d) A powerful Ejector (for drying sterilized linen) circulates air through the chamber. The circulating air passes through a corrosion resistant metal wool filter.

(e) A Dial thermometer is provided to indicate the chamber temperature.

(f) Automatic vacuum breaker is provided to break vacuum in case of vacuum formation due to steam condensation.

Available in Following Capacities
