The heating season is in full swing, so district heating companies are making every effort to ensure that heat reaches even the most remote consumers. In recent years, transmission networks have undergone extensive modernisation. Energy companies are investing in the design and construction of district heating networks using pre-insulated materials.
What about the valves and piping located in existing chambers?
These components are often left uninsulated. This leads not only to an increase in air temperature within the chamber, but above all to significant energy losses.

SUM Maintenance Guard covers effectively reduce heat losses in district heating chambers and improve the efficiency of both existing and newly constructed transmission lines.

They ensure quick access to valves during maintenance work or in the event of a failure. Maintenance teams no longer waste valuable time ventilating the chamber before entering.
Thanks to their mechanical durability, the covers are resistant to flooding with water or brine. Yes, brine‼️ District heating chambers are often located within transport routes, i.e. directly beneath roads. In winter, water contaminated with oils, salt and other chemical substances flows into the chamber, flooding the covers.

The durability of the covers makes them an effective insulation solution for years of operation. The average service life is ‼️10 years‼️

Marking of covers – coloured stripes facilitating identification

In recent years, we have introduced special markings on our covers to facilitate the work of district heating network operators. Blue and red stripes have been used to indicate supply and return lines. This is another modification introduced at the Client’s request, enabling faster installation and removal of the covers.
At SUM, we not only provide the highest-quality solutions, but also remain flexible and always take our Clients’ needs into account.
