AERCO Benchmark Platinum 

The Benchmark Platinum features a powerful bundle of innovative technologies including AERtrim, a patented O2 Trim technology, Dual Returns, and onAER Remote Monitoring, in addition to an industry-best warranty. A key advantage of the Benchmark Platinum series is its dual return capability, which allows engineers to take full advantage of diverse load demands specific to a site in order to design the most efficient system possible. The dual returns keep cold water separate, creating a larger condensing zone in the heat exchanger that improves boiler efficiency up to 7 percent.  Dual returns are ideal for applications that feature combination systems including multi-zone space heating, space heating with domestic hot water radiant floor heating, snow melt, pool heating and more. AERtrim monitors actual site conditions and self-adjusts its combustion process to ensure the boiler is operating at optimal O2 levels despite environmental variations. The onAER Remote Monitoring continuously monitors the overall health of the system and provides a convenient site that offers an instant, intuitive, easy-to-read overview of a system including unit performance, plant efficiency, detailed technical data and more. Monthly reports and instant email alerts notify facility managers of any faults or decline in equipment to prevent unnecessary wear-and-tear as well as premature failure.  AERCO www.aerco.com

They can be vented using CPVC, PVC, PP, PP Flex, Stainless Steel AL29-4C, IPEX type IIA & IIB for use with single-pipe, two-pipe, or concentric configuration. Buderus SSB boilers have a 5:1 turn down ratio, an onboard control that includes a combination of weather compensation, mod-bus and BACNET connectivity, a two-wire cascades link, plus terminal wiring, and optional 0-10 VDC interface module. They also feature a factory installed low-water-cutoff and safety temperature high limiter with a manual reset to speed installation. Also, factory-installed in the larger units (sizes 512 to 1024 MBH) is CSD-1 -compliant low and high gas pressure switches. The two largest commercial size units feature side-by-side twin heat exchangers for efficiency and redundancy.  BOSCH THERMOTECHNOLOGY CORP. boschheatingandcooling.com

Bradford White MagnaTech

Every commercial heating system is unique and requires a boiler that can adapt and respond to system fluctuations, while maintaining the energy conservation standards important to today’s building owners.  Such a boiler now exists in the innovative Bradford White Brute MagnaTech.  Traditional boiler pumps are typically sized for the maximum capacity – a pump’s power consumption can drop by as much as 50 percent with only a 20 percent reduction in speed.  In contrast, the Brute MagnaTech utilizes Variable Speed Pump Control Technology to match the modulation rate of the unit’s combustion system to the rate of a variable speed boiler pump.  This unique on-board control allows the Brute MagnaTech to mirror the heating system’s profile during varying load conditions and optimize overall efficiency.  BRADFORD WHITE CORP. www.bradfordwhite.com
