Model plan

If you work with us for the first time or you want to realise several projects with similiar characteristics, we can provide a frame concept for your plans. Considering the most suitable solution for your targets, our recommendations are based on profound experiences of strategies, concepts and components that have already been proved in practice.

Project initiation
and specification

When a model concept becomes a concrete project, the specific details are filled with life. Core task of the first construction meetings is the technical clarification of all plant parts and data points with the heating, ventilation, air conditioning, electrics, plumbing and refrigeration subsections. The adherence to the model concept considering project-related peculiarities is paramount. When all questions have been clarified with the constructor and the companies involved, the planning of the ECOLINK plant can be started.

Project planning

The planning created by GTM contains control cabinet, electronics, sensor technology, MSR software, control schemes, data point lists and project documentation.

Our CAD team creates the ECOLINK circuit diagram with the latest tools. At the same time, our MSR experts are programming the individual control software. Together with the implementation planning, the documentation forms the basis of the later connection to FRIGODATA ONLINE.

Control cabinet production

As soon as the planning and programming of functions is completed, Wurm Schaltanlagenbau starts with the manufacturing of the control cabinet. State-of-the-art production methods ensure high quality and short production times. As a result, the control cabinet will be delivered to the construction site safely and on time. 

Installation and commissioning

Connection, first commissioning and functional testing are performed by one of our system partners. All GTM system partners are trained by our team and have sucessfully supported many of our projects. The long-standing cooperation of operators, GTM and regional partners guarantee smooth installation and commissioning. The regional partners take charge of the ECOLINK plant and the management of all subsections involved.

Support & Monitoring

The maintenance and service of the ECOLINK plant are performed by the regional partners. Due to the commissioning, they are familiar with the plant so that problems can be quickly identified and solved in case of an emergency. 

If required, GTM support also provides help in form of testing operating data, plant analyses, maintenance support and clarification of questions concerning building technology. The web platform FRIGODATA ONLINE provides you with numerous tools that may facilitate your energy management according to DIN EN ISO 50001.
