PP tempering furnace up to 450 / 650 / 850 °C

The smallest furnace with air circulation that is suitable even for temperatures below 600 °C

Even heating of the charge thanks to horizontal internal atmosphere circulation—this is the greatest advantage of this tempering furnace. The precision of the temperature distribution, its guided increase and decrease and controlled cooling (at additional cost) will, when used together, give you complete control over the process taking place within the furnace’s chamber.

PP furnaces are regularly used in industry, and so they are truly robust and sturdy, and the smaller volume furnaces are also very compact and space-saving. Ideal for a laboratory. If you treat them with at least a little respect, they will stick around with you for a good long time. Not just any old lab is going to throw an industrial furnace off balance.
