PREFERRED can do the job
and do it BETTER!
Another one of a long lie! ot exclusive "quality features'* of the Preferred Unit Steam Generator is the Expansile Pre cipitator which helps "Preferred" to do the job better . .., because if is designed and engineered to perform better!
This Preferred component enables maximum gas velocities to be equally maintained in all tubes of the pressure vessel. This is particularly important in-lhe last pass where any drop in velocity (due to obstructions or insufficient mechanical impetus) results in rapid build-up of deposits. The expansile precipitator prevents this build-up, thuB minimizing mainte nance costs. The Preferred Expansile Precipitator is your overall insurance (or clean, smokeless operation and healthful working conditions . . . trapped impurities cannot escape to surrounding areas.
.
The Preferred Generator gives economical, low-maintonance service at a minimum guaranteed, efficiency of 80% . . . for twenty-five years. The Preferred Unit Steam Generator is insurance for optimum combustion based on automatic and simplified operation.
