The company’s line of steam and hot water firetube boilers is highlighted in this four-color brochure. Benefits such as lower fuel cost, nonpressurized venting, and easy installation are detailed. The company says that its Turbopower boiler is a modernized version of a Scotch Marine boiler and contains a submerged combustion chamber with completely water-backed, U-bend steel firetubes. This design is engineered to improved the efficiency of heat transfer by increasing the velocity and turbulence of flue gases as they move across the heating surfaces. — PVI Industries, Inc.
