SI–431A Dry Heat Sterilizer "HEPA Filtered Fresh Air Suction Device (Sterile Hood)"

Most suitable for use in controlled areas / clean room Temp. from 50 to 250°C ± 1°C controlled by digital Temp. Controller cum Indication

Introduction :– Pursuant to our continuous R&D, these Dry Heat Sterilizers have been specially developed, keeping in view requirement for use in controlled area like parenteral section in pharmaceutical industries & clean rooms, in Electronics Industries, Research Lab., Medical & Agriculture, Space Research, Atomic Energy etc. These are also known as “ Sterile Hood”.

Salient Features :– The unique modular design of these Dry Heat Sterilizer have the built in advantage that fresh air is sucked into the sterilizer through HEPA filters, which are DOP tested for efficiency of 99.97% down to 0.3 micron particle size. Pre-filter is also provided to extend the life of HEPA filter. The specially designed air blower unit has balanced, light weight, blower & motor of reputed make. The air recirculation system ensures uniform heating of the chamber & works on the principle of heat convention & hot air recirculation. Air exhaust outlet is also provided to make up for fresh air. It is easy to replace the filter.
These have been aesthetically designed with functional utility & efficiency. These equipment are very useful for use in controlled/clean areas in pharmaceutical manufacturing & find wide acceptance in variable application in different industries engaged in manufacture of sterile product. In the heart of design of these equipment is the principle of judicious combination of Dry Heat Sterilizer with built in “HEPA Filtered fresh air suction device. These are most suitable for use in controlled areas/clean room. Temp from 50-250°C ± 1°C is controlled by digital temp. controller cum indicator (D.T.C).

Construction :– These are of tripled walled construction.
Outer Body :– Made of CRC sheets duly pretreated for surface treatment in seven tank dipping process & epoxy powder coated for attractive finish.
Inner Chamber :– Made of highly polished SS sheet or anodized aluminium. It is provided with arrangement for keeping shelves at convenient height.
Shelves :– Made of SS sheet / Aluminium Sheet, as per material of chamber, are provided.
Middle Walls :– Made of G.I. Sheets.
Insulation :– The gap between the outer & middle wall is filled with special grade insulation to prevent heat loss.
Heating Element :– Heating Element of suitable capacity, are provided in the air circulation path. These are made of high grade nickel chromium wire & duly insulated.
Temperature Control :– Temperature controlled by Digital Temperature Controller cum Indicator (D.T.C) from 50°C to 250°C ± 1°C. The temperature can be easily set & in indicated & controlled by the controlled as per requirement.
Ventilation :– Air Ventilator ports are provided.
Fresh Air Filtration Device :– Fresh air is sucked into the sterilizer through suction devices comprising of HEPA filter, Air blower motor unit, ducting & air circulation plenums around the chamber. Rest air is recirculated.

Control Panel :– The control panel housed with DTC, ON/OFF Switch, Indicating light, high/low temp. switch etc., is easily accessible.
Power supply :– Equipment is suitable to operate on 230V, 1 phase, 50 Hz, AC supply. It is supplied complete with cord & plug.
