SUMMARY:Managing Legionella with Thermal Design (1 PDH)
DESCRIPTION:This educational program on managing Legionella focuses on domestic hot water (DHW) recirculation systems\, thermal disinfection strategies\, and digital mixing valve technology. It is featured in technical seminars and event sessions like the Coffee with Caleffi educational series.\n \nCourse Topics and Learning Objectives\n\nPathogen Basics: Understanding Legionella bacteria origins\, growth danger zones (80°F to 110°F)\, and health impacts like Legionnaires’ disease.\nSystem Design & Mitigation: Eliminating pipe stagnation and dead legs via proper hot water recirculation and flow balancing\nThermal Disinfection Mechanics: Raising system temperatures (typically 140°F to 160°F) for specific time durations to safely kill bacteria during low-use hours.\nHardware Requirements: Evaluating master mixing valves\, comparing electronic versus thermostatic controls\, and utilizing components like the LEGIOMIX® digital mixing valve.\nSafety and Anti-Scald Protection: Deploying ASSE 1070 point-of-use mixing valves to protect end users from high-temperature thermal spikes.\n\n  \nWho should attend – HVAC engineers \n  \n1.0-PDH           Duration:  1-hour                PS# TBA \n
