The benefits of ProEconomy's Orca system

No resistance

Research suggests that because the Legionella bacteria are killed by the copper and silver ions and not suppressed, development of resistance, which is seen with the temperature control regime and chemicals, is unlikely.

Since 1993 Orca systems are successfully controlling Legionellla in many water systems and the development of resistance has never been an issue.
