What type of boiler would typically have a Tri indicator?

A Tri indicator, often referred to as a tri-color indicator, is commonly associated with hot water boilers. This indicator serves several crucial functions, providing visual cues regarding the status of the boiler system. Specifically, it can indicate the temperature and pressure levels, which are vital for the safe operation of hot water boilers.

Hot water boilers operate under specific pressures and temperatures that need to be monitored continuously to ensure safe and efficient performance. The Tri indicator helps operators quickly assess whether the system is within safe operating parameters. In contrast, other types of boilers, such as steam and industrial boilers, may employ different monitoring and control systems, and a Tri indicator may not be a standardized feature for those systems.

Thus, the association of a Tri indicator with hot water boilers reflects its role in ensuring that these systems function safely and effectively, highlighting its importance in the context of monitoring and maintaining proper operational conditions.
