Laboratory furnaces are important and necessary in laboratories and industrial processes such as drying, heating, cleaning, thermal treatments and more.There are a wide variety of furnaces for different uses.When purchasing a laboratory furnace, you need to know the characteristics of the furnace, and make sure that the various parameters are appropriate for the work process.For example, the volume(liters), temperature ranges (degrees Celsius), the purpose of use, how to use it.
Choosing a suitable furnaces up to 3000 degrees Celsius
Temperature Of Furnaces
The required working temperature determines the choice of the furnace.
If working at a temperature of 1100 Celsius, choose an furnace that reaches up to 1200 Celsius.
If working at 1400 Celsius, choose an furnace with a maximum temperature of 1500 Celsius.
If working at 1600 Celsius, choose an furnace that reaches 1700 Celsius.
You can work with the furnace at its maximum temperature for short periods of time, working at the maximum temperature.For a long period of time it will shorten the life of the heating elements.
Heating Elements For Furnaces
The furnaces differ from each other in their heating elements, in their thermal insulation, and in the way they are held in insulation.
Furnaces up to 1200 Celsius are constructed of spiral heating elements threaded or cast in thermal insulation. They are threaded from the right and left ear.
Furnaces up to 1600 Celsius are built of heating elements in the shape of SILICONE CARBID rods, they are threaded horizontally from end to end.
Furnaces up to 1800 Celsius are built from heating elements of MOLIBDINUM DICILICIDE. They are threaded from the ceiling vertically close to the sides.
Concealed or visible heating elements (ASHING Furnaces)
There are processes mainly in the testing of ash. Materials that may attack the heating elements emerge: organic materials, plastic materials, sludge, etc. In these cases it is important to choose an oven where the heating elements are protected.
Work in an atmosphere of gases
There is an option for a retreat to work in an inert atmosphere, the retort is made of inconel and allows work with inert gas flow.
The return can be obtained with a connection for the entry of a thermocouple sensor that enters the return to control the parts inside the return. With employees with hydrogen an extra explosion protection system is needed.
Laboratory furnaces / industrial furnaces
Best Lab Furnaces:
Drying ovens are ovens with an internal compartment. Made of stainless steel. And are designed for temperatures up to 300 degrees Celsius. The heat transfer is in a natural flow in the air or with a blower or with a fan. Acceptable for use in research laboratories, academic institutions and industry.
The Applications of Drying Oven
-Drying and sterilization of utensils like glassware after rinsing
-Heating of parts
-Heating of electronic or medical products pitcher test them under the influence of heat.
What to consider when choosing drying ovens:
When choosing a drying oven, find out if solvents or explosives are dried, and whether it is intended for a clean room.
High Temperature Furnaces
These Furnaces have an inner compartment made of bricks in which the heating elements are integrated for a temperature of up to 1200,1600,1800 Celsius. The heat transfer is done by radiation.
The Applications of furnaces
-Treatments in metals, ceramics, glass
- Thermal treatments
-Burning organic materials
What to consider when choosing furnaces:
Find out if an inert atmosphere is needed, and if a programmer is needed to create a temperature profile.
vacuum oven / vacuum furnaces
Vacuum ovens are heaters with an internal chamber. Made of stainless steel. Designed for temperatures up to 200 degrees Celsius, heat transfer is made through the inner walls in contact with the shelves.vacuum furnaces can reach 1000 degrees Celsius.
The Applications of vacuum furnaces / vacuum ovens
-In processes that require lowering the working temperature such as drying solvents (to prevent explosion) or drying plastic (to prevent melting).
- Drying that requires the removal of bubbles such as epoxy castings.
Tube furnaces are pipe-shaped furnaces made of quartz or alumina for temperatures up to 1200,1600,1800 Celsius. Tube furnaces are designed for treatments of metal parts, ceramics and vacuum.
What to consider when choosing Tube furnaces
Find a diameter and length heated, vertical or horizontal.
In conclusion-Laboratory and industrial furnaces are very diverse and suitable for different needs. You are welcome to consult our professional consultant who will help you make the right choice for you.
