Redesigned, the Benchmark 3000 (BMK3000) boiler features high turndown for energy efficiency, lower operating costs, and high reliability in a compact footprint. Incorporating the company’s stainless steel, fire-tube design, the boiler can satisfy environmental requirements, and provides flexibility to fit in both retrofit and new construction that require one or multiple 3 million Btuh boilers. Delivering 15:1 turndown, the redesigned BMK3000 has operating efficiency of 93.5 percent to reduce operating expenses and maximize seasonal fuel savings, and has a 22 percent smaller footprint than the previous 3-million Btuh Benchmark unit. The BMK3000 has a new stainless steel construction that offers higher efficiency and greater heat exchanger cycling resistance. The patented Oxygen Level (O2) monitoring system can display the O2 level directly on the boiler’s C-More™ Control Package in real time. The monitoring system can be remotely accessed via Modbus or Intranet, enabling the boiler’s emissions level and fuel economy to be measured without traditional calibration devices. The boiler delivers <30ppm NOx at all firing levels, making it an ideal choice for environmentally friendly projects, said the company.
