The Danger of Legionella
Legionella bacteria is the cause of Legionellosis, a collection of infections whose severity varies from mild febrile illness (Pontiac fever) to a potentially fatal form of pneumonia (Legionnaires’ disease) that can affect anyone, but principally affects those who are susceptible due to age, illness, immunosuppression or other risk factors.
Water is the major natural reservoir for legionellae, and the bacteria are found worldwide in many different natural and artificial aquatic environments, such as cooling towers; water systems in hotels, hospitals, homes, ships and factories, respiratory therapy equipment, fountains, misting devices and spa pools.
Control of Legionella is Difficult
Guidelines implemented by hotels and hospitals recommend that the hot water temperature at the tank be 140°F (60°C) and the circulating hot water temperature be 124°F (51°C), but this is not enough. Scientific studies show that peripheral sites remain heavily colonized despite elevated recirculation temperatures (>140°F [>60°C]).
Other disadvantages of raising water temperature further include the risk of scalding and the added energy costs.
SRBL Kills Legionella and Saves Energy
SRBL is the most effective legionella control solution for water circuits officially approved by a government agency as complying with the strictest norms to control legionella even at peripheral pipes.
The system consistently delivers zero legionella and bacteria count in the mandated periodic water tests conducted in the installation sites.more
