The Mach™ Series commercial boiler combines cast aluminum metallurgy with advanced burner and control technologies to create the quietest, most durable condensing hot water boiler today, states the manufacturer. It is 92-percent efficient, and under certain operating conditions, the efficiency can be up to 99 percent. It operates across a 5:1 turndown ratio, which is adjustable from 20 percent to 100 percent of rating. It achieves peak efficiency at part load. Features include a variable-speed fan and zero-offset fuel-air ratio controller. Burner management and operating controls are combined in a unitary, microprocessor-based control, and a digital touchpad displays the operating parameters of the boiler.

Patterson-Kelley, 100 Burson St., East Stroudsburg, PA 18301; 877-728-5351; 570-476-7247 (fax); info@patkelco.com; www.pkboilers.com.
