The contract for the collection of special equipment in the grid areas of the contracting authorities has already been awarded (2017 / S 050-092660). Now special companies are looking for the adaptation of special equipment from L to H gas. The changeover times are distributed as follows:

Energy Networks Middle Rhine: 2021, 2022, 2023

Stadtwerke Neuwied: 2022

Stadtwerke Andernach Energy: 2022

Stadtwerke Troisdorf: 2021

To account for the different device specifications, lots were made. Applicants can apply for one or more / all lots. The specific number of gas appliances to be adapted per batch is still unknown and can not be estimated seriously.

In this context, it should also be borne in mind that some special final consumers may themselves adjust their special equipment. Against this background, a framework agreement should be concluded in the present case, from which the necessary adaptation services can be called up, if necessary.

The adaptation of conventional industrial burners (eg gas blower burners, ring burners, tube burners, etc.) must be carried out. This includes in particular: analysis of the collection of equipment, procurement of spare parts and materials required for the adaptation, checking of gas appliances for defects, functional and exhaust gas analysis, marking of gas appliances and documentation of all work carried out on the equipment and all organizational activities carried out in connection with the adaptation. The execution of the services is based, among other things, on the requirements of the DVGW regulations G 680, G 676 B1 and G 695, as well as their normative references.

It is the adaptation of industrial thermoprocessing equipment - industrial furnaces (stoves, eg chamber, trough, tub, shaft furnaces, etc., continuous furnaces, such as drum, tunnel, rotary kilns, etc.) make. This includes in particular: analysis of the collection of equipment, procurement of spare parts and materials required for the adaptation, checking of gas appliances for defects, functional and exhaust gas analysis, marking of gas appliances and documentation of all work carried out on the equipment and all organizational activities carried out in connection with the adaptation. The execution of the services is based, among other things, on the requirements of the DVGW regulations G 680, G 676 B1 and G 695, as well as their normative references.
