Preheating furnace in dental technology

Preheating furnaces are mainly used in dental technology, but they are also indispensable in the automotive industry. For example, a laboratory oven of this product category is used to bring certain nonwoven moulded parts up to temperature before they are fed into the cold press. This serves to reduce the dwell time in heating presses and to work more energy-efficiently.

Preheating furnaces are indispensable in dental technology. They are used for the controlled burning out of so-called investment materials for model casting prostheses, but also for the processing of moulds. They are also relevant for testing materials in dental laboratories. In addition, prewrmfen are used in the manufacture of various materials. They are also used in the construction of fittings, tools and apparatus.

Structure of a preheating furnace

Without pre-heating, very little is possible in dental technology. What is important is the perfect functionality and the efficient, precise operation of such a furnace. Basically, preheaters consist of a combustion chamber, a chimney pipe, a waste water hose and an exhaust. Depending on the model, maximum temperatures of around 1,200 degrees Celsius are possible. A 4-zone heating system ensures that the material to be burnt is heated evenly from all sides.

Thanks to a special ceramic fibre insulation, rapid temperature increases are possible with comparatively low energy consumption. In the course of the firing process, the model is placed in the heat-resistant inner container, the muffle. This is designed to protect the model casting from direct exposure to heat, ensuring gentle heating and burnout.

Safety regulations for the preheating furnace in the dental laboratory

Regardless of whether they are used in the medical field or in industry, prewarming furnaces may only be used in the laboratory if they comply with certain regulations. Among other things, the environmental conditions according to DIN EN 61010-1 must be observed. The standard defines the safety regulations for all electrical control, measuring and laboratory equipment and therefore also applies to the preheating oven in dental technology.

Further guidelines

With regard to electrical laboratory equipment, the DIN standard specifies which safety regulations apply when measuring, indicating, controlling or examining substances or samples. The preparation of materials and substances for the prewrming oven in the dental laboratory is also precisely defined in the guideline.

Not only must DIN EN 61010-1 be taken into account, but also the Low Voltage Directive 2014/35/EU, since a prewrm oven is a piece of laboratory equipment that requires electrical energy. The following directives also apply:


This standard determines the conformity of medical devices. It ensures that certain conformity procedures are taken into account during manufacture.


This standard applies as a directive for laboratory equipment and for preparatory apparatus for in-vitro diagnostics.


This directive applies to laboratory equipment equipped with communication interfaces, such as WLAN transmitting and receiving devices.
