Parker Boiler Co. is helping treatment plants qualify for lower utility rates by reducing reliance on backup power. One recent example of that was the 41 mgd Roger Road wastewater plant in Pima County, Arizona.

To qualify for the lower rate and maximize the use of digester gas, the staff installed a Parker TC Series boiler to heat five digesters, eliminating the need to tap an engine-generator for digester heat.

The TC Series features a front door that swings open to allow easy cleaning of the chamber and tubes. The boilers also include a Siemens LMV parallel positioning system for fuel/air ratio control.

Parker Boiler Co. is a manufacturer of industrial and commercial steam boilers from 1.5 to 150 hp with pressures to 250 psi capable of delivering dry steam in fewer than 10 minutes. For more information about the company’s boilers: 323/727-9800 • sales@parkerboiler.com • www.parkerboiler.com
