Control system for modular boiler plants
AERCO Control System (ACS) is a flexible controller designed to maximize energy savings in modular boiler plants.
The AERCO Control System (ACS) is a flexible controller designed to maximize energy savings in modular boiler plants. The ACS can stage and coordinate the operations of up to 32 boilers and is uniquely designed to maximize the operating efficiency of condensing equipment. Eight of these 32 boilers can be designated for domestic heating priority. Another eight boilers may be designated as swing boilers serving domestic hot water and building space heating as demand requires. With individual unit turndown as high as 20:1, a five-boiler plant delivers 100:1 system turndown when staged to operate sequentially. Able to regulate overall plant output with precise accuracy, a boiler plant with ±2 F header temperature variation is assured under normal load conditions. The ACS offers sequential or parallel operation flexibility, 100% control of auxiliary equipment, and user programmable modes of operation that can be changed in the field. It automatically rotates the lead unit to help equalize boiler runtime.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
