For all water bath and steam-heated distillation units with up to a 6000-liter filling capacity.
As of June 2002, all distillation units operating with an overpressure of 1 bar have to be designed and manufactured in accordance with European Pressure Equipment Directive 97/23/EC and bear a CE label compliant with this directive. Equipment without this CE label may only be operated at a maximum pressure of 0.5 bar.
Therefore, earlier this year, Arnold Holstein GmbH applied for TÜV (German Safety Standards Authority) certification, i.e., an EC type examination was conducted for all distillation unit types included in the delivery program of Arnold Holstein GmbH.
This type examination guarantees that all manufactured distillation units comply with the requirements stipulated by this directive.
Any materials used in manufacturing the equipment and all safety-relevant mounted parts must comply with the directive and be accordingly certified. In order to ensure consistent work quality, all welding specialists involved in the production of the devices have to undergo periodic examinations conducted by TÜV.
The certification procedure was successfully completed in July, which ensures production quality of the highest level and compliance with the latest standards and regulations in the future as well.
