Adding to its growing line of cast iron boilers, the F.W. Webb Company has unveiled a new commercial-grade boiler under the acclaimed TRIO® brand name. With a highly efficient, 3-pass design, the new TRIO offers multi-fuel flexibility through the choice of either an oil or gas burner. The low mass European design with AFUE ratings up to 87% is what makes the TRIO commercial boiler a standout in its class. The GG20 cast-iron block with its 58 PSI rating provides exceptional durability for years of trouble-free operation. And the easy-access swing door provides superior serviceability. The TRIO Commercial heat exchanger path is up to 15 feet in length, and the 3-pass design heats more surface area per gallon burned, with 25% less heat lost than pin-type boilers.
With seven models to choose from, ranging from 240 to 629 MBH, the new TRIO commercial boiler is an excellent choice for commercial or multi-family buildings. All models have been tested extensively, are ASME certified and come with an industry-leading 20-year limited warranty.
