The Charleston Fire Department announced Friday it had bought three new fire engines to replace aging apparatus at several fire stations.

Each of the three 2013 Pierce Arrow XT fire engines is equipped with 1,500-gallon-per-minute pumps and with booster tanks that hold 750 gallons of water, according to a news release.

The pumpers will replace a 1994 model that was at Station 3 downtown, a 1994 model at Station 16 in West Ashley and a 1997 model at Station 13 on James Island.

"The addition of these three engines continues the city's commitment to upgrading the fleet with state-of-the-art apparatus," said Fire Chief Karen Brack. "The increased firefighting capacity, improved safety features, equipment upgrades, and standardization of the fleet are providing the firefighting force with the best tools to protect our community."

Safety features in the new pumpers include seat belt monitoring systems and headset systems that provide intercom capabilities and hearing protection for the firefighters, the release said. Each pumper can carry five firefighters.

Fully outfitted and equipped, each engine cost $521,824, said Capt. Ryan Kunitzer, a Fire Department spokesman. The total cost for the three engines was $1,565,472.

The older engines will be put into reserve status, Kunitzer said.
