Description and Specification for Lab Tenders
Astra Scientific Hot Air Oven.
Utilizing forced air circulation, hot air ovens are used in laboratories
to perform effect of ageing on various physical properties of any type
of materials including yarns, fabrics and paper etc; in addition, these
forced air convection ovens are also used for high quality drying and
baking applications in the field of laboratory, medical or biomedical
and pharmaceutical and textile industries, where fast heat up and
consistent temperature are prime requisite. Often known as hot air
circulating ovens, these units are fitted with blower or fan inside in
order to distribute hot air (warm air) in every corner of the inner
chamber. Physical properties of materials are analyzed before and after
ageing in order to find out their suitability for specific applications.
Our hot air oven systems offer continuous temperature up to 250°C and
feature safe operation; allowing operators to worry-free perform their
tests. Standard models of our hot air ovens are available from 22 liters
to 300 liters volume; however, we can design and manufacture hot air
ovens meeting customer provided temperature range, sizes and capacities.
There are various optional accessories that our company can add on
extra cost in order to make your working more comfortable. Under
economical price, our hot air ovens deliver superior quality drying
facilities.
Features:
Up to 250°C temperature Temperature safety as per DIN 12880 Class 3.1
Precise and even heat distribution Noise-less fan
Safe for operator and samples Double walled construction
Removable stainless steel shelves Digital temperature controller
Over heat and over current protection Forced air circulation
Ventilation of gases Imported heating element
Temperature:
All hot air ovens provide temperature range 5°C above ambient to 250°C
with accuracy of ±2°C. Temperature is controlled with mechanical
temperature control (rotary knob) or by digital control (PID
controller). For uniform rotation of heat inside the chamber noise-less
fan is used for air circulation.
Construction:
Each hot air oven is produced with double walled construction and made
of 304 grades stainless steel with insulation of mineral wool for
efficient thermal loss. In economical models, exterior chamber is made
of powder coated MS, while 304 stainless steel is used as an option.
Inner chamber is completely made of stainless steel, which is easy to
clean and maintain. Shelves are made of painted steel and can be easily
adjusted inside the chamber with ribs created inside the interior
chamber walls.
Doors:
Doors are double walled, made of MS steel (stainless steel optional) and
also fully insulated with mineral wool, fitted on heavy hinges. Sturdy
handle provides comfortable opening and closing. Doors open 180° in
order to provide enough access to the heating chamber.
Heating Elements:
For efficient heating, our hot air ovens are fitted with branded heating
elements, nickel / chrome plated nichrome wire, kept inside the beads
and placed at the bottom and both sides of the chamber.
Ventilation:
For safe removal of hot gases and fumes air ventilators are provided near the top of the both sides.
Safety Features:
For safe operation of hot air oven, several safety instruments are
fitted; automatic circuit breaker turns off the unit in case of over
temperature and other short circuits. Audio and visual alarms can be
fitted as option, alert the user if temperature goes beyond the
selection.
