ESHC® (Entire Surface Heat Conductor) is a highly efficient heating technology developed in Germany that is used in process heat. Among the users are large German DAX companies as well as important biotech companies. For example, this heating technology is used to dry tissue samples in pathology in order to examine them under the electron microscope of leading lab equipment manufacturers. This application only allows a tolerance of a mere 0.5 °C.

 

The special aspect of this heating technology which is only used by Welltherm is that more than 70 % of the surface to be heated is covered by heating conductors. This guarantees excellent heat distribution and associated high efficiency. For competitors’ products the values are between 6 % and 23 %!

A direct comparison of ESHC® technology with other infrared heating systems

Thanks to long-term research and development work, Welltherm GmbH has a profound knowledge of all heating systems represented on the market. Due to extensive tests and lab analysis by independent facilities, we have concrete measurement results available for the radiation factor, and with that the proportion of radiation, of the heating systems below. Basically, the following applies: The bigger the proportion of radiation of an infrared heating system, the more efficiently this will convert electrical energy (power) into thermal energy (heat).

The level of radiation is calculated from the ratio of the radiation factor in reference to a maximum radiation efficiency of 0.7. The radiation factor was measured by way of a measuring process based on DIN EN 416-2 and IEC 60675. This describes the ratio of radiated infrared power to the electrical power used and is expressed as a percentage value.

 

Conclusion: With ESHC® technology we can save up to 30 % of heating costs compared to other technologies.

Construction of the Welltherm ESHC® infrared heating system in detail

The exploded drawing above shows the schematic construction of Welltherm infrared heating systems. The extensive ESHC® heating conductor geometry made from highest-quality stainless steel is clearly visible in the middle. Reverse heating circuits reduce unwanted magnetic fields to a minimum. At the front and back the heating element is surrounded by thermally resistant silicone insulations. The material strength used for this insulation is only 0.8 mm and leads to optimum heat transfer to the front of the infrared heater, with maximum safety. In order to best reduce the loss of radiated heat energy at the back, we use a thermally insulating mat.

CE

The CE marking is an administrative symbol for the European Single Market. It declares that the product to which it is affixed fulfils all the requirements for the EC directives for this product. The CE marking is essentially not a consumer mark. It serves first of all as an “EC passport” for a product and means that this product may be put on the market in every Member State within the EC. CE signals the compliance with requirements for the guarantee of safety as well as the protection of health and the environment.

VDE

The VDE certification mark for electrotechnical products is awarded by the German Association for Electrical, Electronic and Information Technology (VDE). It denotes conformity with VDE regulations or European or internationally harmonised standards and confirms compliance with the protection requirements of the applicable guidelines. The VDE mark certifies compliance with high safety standards for electronic devices, for example concerning electrical, mechanical and toxic aspects.

GS

The seal Safety Checked (GS mark) certifies a product ready for use that complies with the requirements of § 21 of the Product Safety Act (ProdSG). In contrast to the CE marking, the GS mark can be affixed voluntarily. It postulates a successful test, certifying that the product complies with the statutory requirements for product safety. The product subsequently undergoes regular controls. The test is conducted, for example, by the TÜV.

VDE EMC

Electrotechnical products must not only work properly and thus be safe and interference-resistant. They must also not influence any other devices while in operation or cause prohibited circuit feedback. The VDE-EMC mark confirms that the marked products fulfil all requirements set by the standards for electromagnetic compatibility (EMV).

RoHS

RoHS is the abbreviation for “Restriction of Certain Hazardous Substances”. The RoHS EC Directive serves to limit the use of certain hazardous substances in electric or electronic equipment. It regulates the use and placing on the market of hazardous substances in electric equipment and electronic building elements. This single market directive applies to all EC Member States.

Made in Germany

The designation Made in Germany is purely a designation of origin and was originally introduced at the end of the 19th century as a means of protection against imported or plagiarised goods. Fundamentally, the designation “Made in Germany” requires manufacture in Germany. Nowadays the seal is seen as a seal of approval. It confirms that the product is of a quality that conforms with German value concepts.

DIN EN ISO 9001: 2015

At the beginning of 2017 Welltherm GmbH received the quality management certification according to the new worldwide valid norm DIN EN ISO 9001: 2015. The ISO 9001 quality management norm is the most common nationally and internationally norm in the quality management of modern companies. This means that Welltherm GmbH is one of the few manufacturers within the infrared heating sector who have a certification.
