Gas Sterilizers

 

We are one of the distinguished manufacturers of a comprehensive range of Dry Heat Sterilizers that is manufactured utilizing high grade stainless steel of 316 grades and thus considered better than that of steam sterilizers. These sterilizers are in accordance with GMP standards & temperature uniformity in the entire chamber is guaranteed. Our range of sterilizers is generally used for sterilizing and depyrogenation glass and metal ware including ampoules, injection bottles, infusion bottles and production equipment. Also known as pharma equipment, it is used to sterilize liquids with low moisture content and also for treatment of medicated  powders as the process of sterilizing completely destructs all micro-organisms and does not cause any environmental pollution or inconvenience to humans.

 

These are provided with PLC operated fully automatic control panel that automatically controllers the different cycles of the sterilizers such as exhaust cycle, pre-sterilization, sterilization, stabilization and cooling.

 

Salient features of our Dry Heat Sterilizers are as follows:

 

• Total cycle time only 4 hrs.
• Belt driven motor for main blower. This eliminates the frequent problem of motor getting heated up and frequent replacement of motor bearings
• Heater terminals fully copper strip wired to eliminate any particle generation by burning of wires
• Unique pressurized locking system for 100% leak proof doors
• Fully automatic control panel with memory circuit
• Additional safety digital temp controller as back up for overheating
• Thyristorised cum contractor back up control for heaters
• Total concealed wiring
• Eight probes for temperatures at different points with provision to insert additional probes for validation
• Continuous generation of documents for validation for every batch
• Memory circuits in case of power failure
• New features as critical temperature & stabilization band to ensure uniform circulation and proper sterilization of every batch
• Four different memory options in the plc for four different programs
• User name, code no, date, real time and set parameters are available in each and every batch printed
• Rapid cooling system for faster cooling
• User friendly functions with pass word locking to avoid any misuse

 

Application areas:

 

• Disposable surgical products
• Pharmaceutical industry
• Laboratories
• Hospitals
• Food industries

 

We are engaged in manufacturing a wide range of Autoclave & Steam sterilizer that is sturdy in construction as it is manufactured using plates of appropriate thickness to prevent buckling under vacuum or bulging due to pressure. These fully automatic PLC base controls help in operating the system work pneumatically with actuated solenoid valves. The vacuum drying at the end of sterilizing hold period ensures drying of the material, which has been sterilized. It is also useful for vials and eye drops entering the class I area and processing drums, garments, fabrics, drying rubbers stoppers vessels machine parts, liquids in bottles and PVC pouches.

 

Features of autoclave:

 

1. Standard Cycle Operating Pressure -1 Bar to + 4 Bar

• Heat up- ster hold (121°C) - exhaust
• Heat up- ster hold (134°C)- exhaust

 

This is the method of gravity air removal to ensure uniform steam distribution and penetration. Steam trap equipped with air vent ensure maximum air removal. It is useful for sterilization of glass containers i.e. ampules, vials, glass bottles. Further, it is also useful for sterilization of glass wares, utensils, vessels, instruments and rubber articles linen.

 

2. HP HV Cycle

 

3. Pre ster vacuum pulses-heat up-ster hold- exhaust

 

4. Pre ster vacuum pulses-heat up- ster hold- exhaust-post ster vacuum pulsing for drying

 

5. Leak Test Cycle for periodic testing of door integrity and pipeline connections & detecting leakage ampoules

 

6. Another HP HV Cycle with post vacuum pulses can be provided, if required for special purpose

 

This above technique is used for 100% air removal from sterilization clamber v, which results in better temperature uniformity in the chamber because of the absence of air pockets i.e. cold spots. It helps in increasing the penetration of steam in porous products from which removal of air is difficult.

 

Features of the sterilizers:

 

• Double door sterilizer to isolate the sterilize and operating sides
• Robust design to use for continuous load and provide tool for production use of pharmaceutical companies
• Carries all the requirements of IS-3829 standard
• Loading carriage and trolley for easy loading, unloading and transfer the material
• Side control valves provide comfortable operation
• High pressure high vacuum cycles to provide the perfect sterilization
• All safety aspects like pressure door lock, safety valves and magnetic low water level protection for water immersion heater

 

 

Specifications:

 

• 1200 x 600 x 600 mm
• 1500 x 600 x 900 mm
• 1500 x 900 x 900 mm

 

Power requirement:

 

• 3 phase 18 kW
• 3 phase 18 kW
• 3 phase 36 kW

 

We are offering a wide range of Ethylene Oxide Gas and System Sterilizers that has been specifically designed for sterilization of products sensitive to high temperatures and to humidity. Our offered sterilizers are extensively used in disposable surgical products, para pharmaceutical and pharmaceutical industry, laboratories, hospitals and food processing industry for sterilization of powders that can be deteriorated by heating exposure. These are basically designed to make the sterilizers work under pressure (1.5 kg/cm² + vacuum) with mixtures of ethylene oxide and carbon dioxide (usual composition 10% EtO + 90% Co², 20% EtO + 80%Co²).

The control systems that are mounted on autoclaves allow performing cycles, automatic control cycles according to type load, packaging and product placing inside the chamber. Moreover, the leak test cycle is offered for periodic testing of door integrity and pipeline connections & detecting leakage ampoule's. The HP HV cycle of the sterilizers with post vacuum pulses can be provided.

Benefits:

 

• Standard cycle operating pressure-1 bar to + 2 bar. This technique uses near 100% air removal from sterilization chamber those results in better temperature uniformity in the chamber because of the absence of air pockets. It increases the penetration of Eto gas in porous products from which removal of air is difficult.
• Vacuum drying at the end of sterilizing hold period ensures drying of the material which has been sterilized it is useful for ampoules in cassettes, small items of processing and packaging  equipment entering the class 1 area and processing drums, garments, fabrics, drying, rubber bungs vessels machine parts, liquids in bottles and PVC pouches.

 

Standard operating values:

 

Sterilization Time	Usual gas exposure time is 3/4 hours. Sterilization time depends on both type of packaging and other process parameters.
Product Temperature	40/60 C set temperature value is non-stop holded by forced circulation of water inside the jacket and, optionally, inside the system is very reliable with no risk of overheating and temperature differences by steam use.
Product Humidity	40/70 RH% Such value is obtained with sterilizer under vacuum condition to allow best conditioning of sterilization load.
Gas Concentration inside the Sterilizer	Variable on the basis of used gas mixture and operating pressure.

Typical (EtO) Sterilization Cycle

 

• Pre vacuum phase
• Vacuum hold phase
• Rh injection and rh hold phase
• Gas inlet phase
• Gas exposure phase
• Gas exhaust phase
• Air wash phase
• Cycle over

Cycle Basic Phases:

 

• Load of product to be sterilized Product heating by heated water circulating inside the jacket which makes heat exchange easier
• Pre-vacuum with value that can be automatically set up to 15 Inch/Hg max
• Vacuum leak test of the chamber before gas inlet
• Product conditioning by humidification up to a preset value
• Inlet of preheated and vaporized gas up to selected pressure value
• Sterilization with gas pressure constant holding for a preset time (up to 24 hours)

 

Our offered range of heat exchanger and condenser is manufactured using carbon steel or stainless steel, brazed plate, plate & frame and shell-tube construction in 1 square meter to 200 square meter size. These are extensively used in space heating and power plants, chemical plants, petrochemical plants, petroleum refineries and natural gas processing, also used as refrigeration heat exchanger and air conditioning heat exchanger. Moreover, we also offer cost-effective customization of the exchangers to meet the varied requirements of the clients.
