How to Control Legionella in DHW Recirculation Systems

Thursday, May 23
12 noon - 1:00 p.m. CDT

With increasing awareness of the dangers of Legionella bacteria in plumbing systems and the rise in reported Legionnaires' disease cases, assuring safe and sanitary domestic hot water (DHW) is more essential than ever. Kevin Freidt, director of product management and technical support, will take an in-depth look at temperature-based disinfection for minimizing the potential of biological contamination in DHW recirculation systems.

You'll learn:
→ What is Legionella bacteria, where does it come from and how does it affect humans?
→ Why do we need to control Legionella in DHW systems?
→ What is thermal disinfection and how does it control Legionella?
→ Is thermal disinfection safe?
→ What are the pros and cons of using thermal disinfection, compared to other disinfection methods?
→ What are the requirements for my DHW recirculation system to do thermal disinfection?
→ Do I need a master mixing valve? If so, must it be electronic? Will a thermostatic valve work?
→ What is the actual disinfection process and how is it implemented?

Freidt is the intellect behind sizing up the best product offerings in a moving target market and manages an exceptional technical support team. He has a B.S. in Mechanical Engineering Technology, 30+ years’ of experience in the commercial HVAC industry and is a LEED AP. Our audience will thoroughly appreciate his academic passion and concise content delivery.
