LEGION 2+M – Panel-Assembled System for Legionella Prevention

DESCRIPTION

The LEGION 2+M panel is part of the LEGION line by STEIEL and has been designed for the constant and complete disinfection of the sanitary hot water circuits, for Legionella prevention.
The biocide analysis system allows a precise and guaranteed dosage for the entire time of use, compensating for any loss of title of the dosed product.
It is suitable for dosing a biocide and a protective product of the hydraulic circuit proportionally to the flow rate of the water to be treated, by means of two specific multifunctional pumps.
The biocide dosing pump features self-bleeding head and reinforced diaphragm, resistant to chlorine dioxide or other oxidant.
The biocide dosage can be proportional to the flow rate and monitored, and possibly limited, by a specific measuring instrument, or it can be proportional to the measurement.
The measurement system uses an amperometric sensor, able to work at high temperatures and under pressure, and also allows to check operating anomalies, such as dirt or failure of the measurement sensor, breaks or leaks on the biocide product dosing line.
The standard version is supplied with accessories to dose a biocide stored in hermetic drums; in case of product stored in normal tanks, order a suitable suction lance.
