Ensuring that rolling stock are freeze-free all winter long
When winter temperatures dip below freezing, passenger trains with potable water-bearing systems for on-board kitchen galleys and sanitary systems are in danger of freezing when the train heat is turned off for switching locomotives or even during brief layovers. If not properly protected, a freeze up can result in burst water tanks and piping, costly repairs and interrupted schedules.
During normal operation, a passenger train’s heating keeps potable water systems warm enough to prevent potentially damaging temperature dips. But, when the train’s heat is turned off during a layover or when the train is being put into storage, the temperature inside of the cabin can quickly plummet towards freezing. If the water in the system is not heated or drained, it will eventually freeze and cause significant damage.
Relying on manually draining a passenger train’s water tanks prior to freezing can be risky when accounting for human error, and continuous idling can be costly and unrealistic. While auxiliary power units are an option, as well, the challenge becomes how best to protect your passenger train when there is no power.
To keep passenger trains freeze-free all winter long, ThermOmegaTech® designed the GURU PC®, an automatic freeze protection drain valve for water-bearing systems.
