What is freeze protection?
• Freeze protection is a heat tracing application. Usually refers to maintaining water line temperatures at slightly above freezing (Tp = 40°F - 50°F). Freeze protection design is simply a matter of selecting a heater to offset the heat loss through the thermal insulation. Freeze protection systems are characterized by relatively low heat delivery and by the fact that their use is generally seasonal during cold weather months. “Freeze protection” is sometimes used to describe moderate temperature maintenance applications (Tp = 90°F or less).
