Buffer Vessel Sunsystem Pr 2000l

For storing the heat generated by the boiler; recommended for the heating installation.
Ensures an optimal operating mode of the boiler, allowing it to run at nominal output even when the installation does not need all the heat produced by the boiler.
The heat is stored and accumulated in the buffer tank and can be used even when the boiler has cooled down.

ADVANTAGES:

• Removable thermal insulation, 100 mm thick, and external PVC casing in RAL 9006.
• Multi-position mounting of the temperature sensor.
• Primed outer surface.
• All connections have internal threads.
• The inlet/outlet connections are positioned at an angle of 180 degrees
• Coil heat exchanger
• Easy installation.
• Optional equipment with an electric kit with a power of your choice: 3 kW; 4.5 kW; 6 kW and 7.5 kW.

ELEMENTS:

1 – Aesthetic PVC casing in RAL 9006
2 – Primed outer surface of the tank
3 – Removable thermal insulation
4 – Tank made of low-carbon steel
5 – Lower coil S1
