Freeze Protection Case Study: Bridge Over Frozen Waters

Ware Shoals, South Carolina, has been plagued in recent winters by expensive repairs caused by freezing pipes. One particular application, a two-inch line mounted on the Marion P. Carnell Bridge over the Saluta River, was especially troublesome. As a result, pipes were constantly being repaired, and water flow was interrupted to hydrants and a hydroelectric station.

The Opportunity

Eastern Industrial Supplies, Inc. had the solution. Jack Sullivan, Eastern’s senior product manager for steam products, recommended ThermOmegaTech freeze protection valves.

“Ware Shoals is my hometown,” said Mr. Sullivan. “Helping the city is much more than a business relationship. So, I was thrilled to introduce a technology to help them solve a problem. ThermOmegaTech freeze protection valves were the perfect answer to lower costs and improve city infrastructure operations.

The Installation of Freeze Protection Valves

Three HAT/FP valves were installed on the bridge to automate purging water from pipes before they could freeze.

The valves are set at 35°F to open reliably and without electricity or human interaction when water reaches a freezing point, which is critical to city operations and residents.

“We were very interested when Eastern Industrial Supplies suggested they have a solution, especially one made with stainless steel and didn’t require electricity or batteries,” said John Lake, owner of L&L Environmental, which manages maintenance operations for Ware Shoals.

“The water line on the Marion P. Carnell Bridge used to be compromised every time we had a cold snap,” said Jordan Gambrell, wastewater supervisor at L&L Environmental.

“The freeze protection valves held up, with no issues, the entire winter. When you are on call 365 days a year, it is reassuring to know I can sleep at night knowing those lines won’t blow when it gets cold,” he said.

The damage caused by freezing pipes isn’t just water under the bridge.

Eastern Industrial Supplies and L&L Environmental can use ThermOmegaTech freeze protection valves to ensure water reliably flows under a bridge to equipment critical to the city’s operations.

About ThermOmegaTech

ThermOmegaTech freeze protection valves have proven to be both reliable and versatile. When the company was founded in 1983, they were initially used to protect locomotive engines. The ability to protect equipment worth hundreds of thousands of dollars has given maintenance supervisors confidence to apply ThermOmegaTech freeze protection valves in several critical Industrial applications. For example, condensate returns, docks/ports, pumps, safety showers/eye wash stations, and water supply lines for livestock all benefit from thermostatic balancing valves. Contact us here.
