Chicago area upgrades to GURU PC® for passenger car freeze protection

The Chicago area commuter regional rail operator has upgraded to GURU PC® for passenger car freeze protection.


Located on the eastern side of the windy city, a Chicago area commuter regional rail operator has an operating range that stretches from the Chicago collar counties up into Kenosha, Wisconsin. With more than 780 passenger cars in their fleet, the company’s trains provide daily transportation for thousands of commuters.
Given their operating range, the rail operator is no stranger to freezing temperatures and is mindful of the need to protect their passenger cars’ potable water-bearing systems from freezing during the cold winter months. Typically supplying on-board toilets and kitchens, these water-bearing systems can quickly freeze when the car heat is turned off, bursting pipes and storage tanks. This can lead to expensive, lengthy repairs and significant downtime. A project manager at the company commented that while they had used freeze protection devices on their passenger cars in the past, they performed poorly. Due to this, they made the decision to switch to the GURU PC® thermostatic freeze protection valve in 2018.
Utilising the same thermostatic temperature control technology as the GURU® Plug for locomotives, the GURU PC® operates 100 per cent mechanically and does not require a source of electricity to drain the system. The GURU PC® is offered in ¾” and 1” NPT sizes, both of which have a high flow design for rapid draining. We recommend purchasing our electric heater assembly, which is offered as 120VAC/74VDC or 230 VAC, with the valve to shorten refill and startup times after a valve activation.
NSF 61 Certified and shock and vibration tested, the GURU PC® is compact, reliable, and in-line serviceable for ease of maintenance. This winter and every other, trust the thermostatic GURU PC® freeze valve to protect your investments from freezing temperatures.
