No quality
without agony

High quality guaranteed by a complete test chain

Our aim is to provide you with the best quality from a sustainable and responsible production. Therefore, we apply efficient quality management measures throughout the company. In this sense, quality not only refers to our products and solutions but is our yardstick for all areas of our company:

  • We develop and produce our software and hardware internally.
  • Every Wurm product is subjected to a complete test chain from the development phase to the final manufacture.  Only when all the tests have been passed in every respect may the device in question be delivered to the warehouse or directly to the customer.
  • The materials and substances we use are exclusively delivered by quality manufacturers that are committed to our sustainability standards.
  • We set our suppliers standards that are as high as those we set ourselves. Thus, we ensure that our suppliers are committed to sustainable production and environmentally safe disposal.
  • Environmentally friendly and resource-saving processes according to strict EU regulations are, of course, important pillars of our quality management.  
  • Our colleagues in the Wurm customer service do everything always to find the best and fastest solution for your request. You can count on their friendliness - without a long wait.

Wurm quality means safety, comprehensive service and reliability.


  • Product testing

Strict assessment of  
all production stages

Highest quality guaranteed by a complete test chain

All of our later product series are already examined in the development phase and, of course, throughout the entire production process. Each device is tested thoroughly by our experienced colleagues at freely programmable test stations. Each test procedure and each defect detected will be documented fully and consistently. Test results make a continuous contribution to the optimisation of our series.
In our EMC laboratory, our products undergo high-stress lab tests with test threshold values that are considerably stricter than those of the industry and legal requirements. 


Our laboratory equipment is state-of-the-art, enabling a variety of destructive and non-destructive tests with rapidly changing electric and magnetic fields.

Moreover, our management system is audited annually by authorised institutions to check the conformity with existing audit standards.

  • Responsible choice of suppliers

Responsible choice of suppliers

Long-term partnerships based on shared values

Quality management begins with a sustainable choice of suppliers. Our components are sourced exclusively from high-quality suppliers. This often results in longstanding partnerships.

With regard to quality and environmental compatibility, of course we set our suppliers standards that are as high as those we set ourselves. An open and trustful communication with our partners contributes to our constant improvement of our products and services for our customers.

Certificates & Audits

Regular audits and certification by external authorities is a natural part of our company philosophy: Thus, the company undergoes annual external reviews of compliance with regulation and the regular improvement procedures by independent, external and licensed certifiers. The focus of these audits is on our quality assurance system and the compliance of our defined quality policy.
After a successful audit a certificate will be issued for a limited period until a follow-up audit is carried out.

We are convinced that these annual external audits are an essential prerequisite for meeting our own high demands on quality, environmental protection and sustainable management.

With their comprehensive monitoring solutions, Wurm have been offering store managers tried and tested online and offline products that enable temperature monitoring and documentation in compliance with HACCP for many years. This was recently certified by HACCP International at the end of February 2019 by independent experts after in-depth testing of our web solutions, FRIGODATA ONLINE and FRIGODOC Xpress, and numerous hardware modules, based on the basic principles of HACCP as described in the Codex Alimentarius of the World Health Organisation.

After a repeat audit in March 2019, our software FRIGODATA ONLINE as well as further software and hardware components were re-certified as “Tested Energy Management” according to DIN EN ISO 50001 by TÜV Rheinland. Thus, all included components are perfectly suitable for a comprehensive energy management system that comprises the collection, transmission, visualisation and analysis of energy data.

As a medium-sized company, we take our responsibility towards environment and society very seriously. Thus, we constantly check our own compliance with ecological and ethical standards and with legal rules. We expect the same high standards from our partners as well. Therefore, we have developed a code of conduct. The document lists the various aspects of sustainability and protection of people and environment that our partners ought to consider. By signing, our partners undertake to comply with the content of the code.

Please, read our Code of Conduct
