– Logalux PR 500/750/1000-120
•
Solar buffer cylinder
– Logalux PNR 500/750/1000-80 E(W)
– Logalux PNR 500/750/1000-120 E(W)
Both types of cylinder are available with 80 mm PU
flexible foam thermal insulation or 120 mm polyester
fleece thermal insulation.
The buffer cylinder is made from steel and equipped with
a temperature-sensitive return feed.
A back boiler or solid fuel boiler can be integrated via the

Correct use
Due to their large volume, the Logalux PR buffer cylinders
and Logalux PNR solar buffer cylinders are designed for
central heating backup.
These buffer cylinders may only be filled with heating
water and used in sealed heating systems. The cylinders
are not suitable for use with potable water.
The buffer cylinders can be used for indirect DHW
heating via a freshwater station.
