100 PPH to 10,000 PPH (10 BHP to 300 BHP) @ 99.5% efficiency Despite its compact footprint, the Model ST’s large steam chest delivers high quality, dry steam with minimum carryover. Fuel-oil or propane boiler retrofits are simpler with a Precision Model ST that requires no vent stack or combustion air louvers and can be supplied in a ‘knock-down’ condition to fit through narrow entries to the old boiler room. The standard ST models can be customized with a variety of factory installed options or configured to connect with field mounted interfaces, giving you exceptional flexibility in design and specification. Adding an SCR creates a boiler with 100:1 turndown to […]

860 MBH to 17,220 MBH (25 BHP to 500 BHP) up to 86% efficiency Flex-tube forced draft design offers high fuel-to-output efficiency in a compact, maintenance-friendly design that harnesses natural heat convection to ensure consistent internal heat distribution and complete internal water circulation. Noted for their small footprint compared to a horizontal fire-tube, the FTH accommodates up to 150oF temperature differences from the supply and return, and offers virtually instantaneous hot water. The FTH can be configured to communicate with any building management system. Other available options include construction under ASME Section I/VIII for high temperature hot water applications.

1,638 MBH to 8,735 MBH (48 BHP to 260 BHP) @ 99.5% efficiency Nearly identical in design and operation to the PCW, but in a larger footprint to deliver higher heating capacity utilizing a horizontal vessel configuration. Like the PCW, standard models can be customized to meet unique installation and control requirements. It can be installed where venting a fuel-fired boiler is not an option. The HW can be configured to communicate with any building management system.  

50 MBH to 1,500 MBH (1.5 BHP to 44 BHP) @ 99.5% efficiency Developed specifically to fit through a 30” door, the standard PCW’s compact footprint can fit where a fuel-fired boiler cannot. When extra options require a larger cabinet, Precision can customize the assembly to supply the boiler in a ‘knock-down’ condition to preserve the design advantages that make the PCW ideal for retrofits, or where venting a fuel fired boiler is not an option.  

330 MBH to 4,100 MBH (9.5 BHP to 120 BHP) @ up to 86% efficiency Traditional vertically configured fire-tube design with better overall efficiency due to under-fired power burner. In addition to the simplicity of the 4-piece design, the FPH includes many advantages over other vertical configured boilers. For example, its larger water volume results in both a low pressure drop thru the unit and reduced cycling, to improve overall efficiency.
