What is a Laboratory furnace
Also called bench type furnaces, ashing furnaces, muffle furnaces, chamber type furnaces, dental furnaces. They have major three parts called electronic control unit, inner chamber and insulation.
The working principle is to heat the air in the chamber heating the element by electricity. Controlling the temperature depends on the performance of the electronic control unit and better performance can be maintained by PID ( proportional-integral-derivative controller) controlled units. Laboratory type furnaces usually do not contain a complicated cooling unit. Most of the time a simple fan system is installed and cooling is performed by this simple fan system supported by a chimney. At the same time, some gases which come out during heating are taken out from the inner chamber through this chamber. This system also helps to remove some corrosive gases from the furnace.
Laboratory type furnaces are designed to heat the specimens up to 1700°C. The most popular furnaces have a maximum working temperature 1100°C – 1200°C. The working temperature depends on your application and and the maximum working temperature is one of the main characteristics to consider when choosing your furnace.

Insulation is an important factor for the performance of a furnace. The higher the maximum working temperature, insulation thickness must be. The outer volume/inner volume ratio gets bigger for the best performing furnaces which have a higher working temperature ( Over 1000°C ) Laboratory type furnaces usually have inner volume between 3 liters – 50 liters.
Application of Laboratory Furnace,
Laboratory type furnaces are usually used to heat small materials or test specimens over 1000°C. Mostly 1100°C-1200°C types are used but it is necessary for some applications to reach up to 1700°C. Here are some of the fields where laboratory type furnaces are used:

- Ceramics Industry
- Brazing and Soldering
- Heat Treatment
- Automotive
- Air and Space Industry
- Coal and Mining
- Plastics
- Electronics
- Glass
- Medicine
- Semiconductors
- Dental
- Research and development
- Material Testing and Quality Control Laboratories
Planed Preventive Maintenance (PPM) Check list.
These are common things have to be considered on PPM but some mandatory things may include in manufacturer's service manual, they depend on the manufacturer and can't predefine for each and every production.
1. check for any deviation between actual temperature and display temperature.
2. Check for leakage current and ensure the safety.
3. Machines can be subjected to corrosion due to high temperature, so check for corrosion and if any remove the rust and fasten the for long lasting.
The water heater maintenance guide is much appreciated. I was not that careful for water heaters before reading that article.
