Aerco expands its Benchmark family with the Benchmark 1.5 Low NOx condensing, fully modulating boiler.
Aerco expands its Benchmark family with the Benchmark 1.5 Low NOx condensing, fully modulating boiler. WIth an operating range of 75,000 to 1.5 million Btuh, the boiler matches fluctuating loads to minimize boiler cycling and eliminate temperature overshoot. Designed with a small footprint, the boiler measures 79 in. H X 28 in. W x 36 in. D and is delivered in a single, fully assembled package that fits in a standard doorway. The model incorporates a stainless steel heat exchanger and Aerco's unit controller and air/fuel delivery system to deliver 20:1 turndown for maximized operating efficiency and seasonal fuel savings. The boiler is individually or in multiple unit designs. In addition to having a constant set point, indoor/outdoor reset schedule, or 4 to 20 mA signal, one or more boilers can be integrated via a Modbus communications protocol to Aerco's multiple boiler management system or facility-wide energy management or building automation system. An optional gateway to support BACnet, LonWorks, and N2 communications also is available.

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.
