The cylinder role in a system is important. It is used to store hot water produced by solar panels or other energy sources (boiler, electrical resistance) that is converted to heat.

All cylinders “BL-S”, “BL-SW”, “BL-DW”, and “BL-ER” bear the CE marking that certifies and guarantees their safe use.

The construction of the cylinders is composed of pure deoxidised copper foil

bonded robotic technology.

For internal insulation ecological polyurethane insulation thermal conductivity k = 0,023 w / mk, density p = 40kg / m³ are used, and resistance to fire class: B3, which ensures heat retention even at very low temperatures.

The cylinder casing is made of stainless steel or pre-painted galvanised steel to protect the insulation and longevity of the internal tank of hot water.

Monophonic electrical resistance (elements) 3kw is used on the cylinders. In case of insufficient sunshine it is possible to use more than one electrical resistance (elements).

It is possible to place coil on the cylinders for the circulation of thermal fluid from the boiler of the central heating or solar system. Where necessary a second coil is used on the same cylinder.

During the construction of the cylinder, hydraulic pressure control is made on the 10 atmospheres (bar).

All types of cylinders “BL-S”, “BL-SW”, “BL-DW”, and “BL-ER” bear a warranty.
