Series 300 Steam

Overview: The Series 300 Steam Boiler is available with firing inputs from 300,000 Btu/hr to 375,000 Btu/hr. However, many millions of Btu’s can be delivered by creating an efficient, fully modular system of up to 24 vessels operated by our computerized control panel.

Design: The Series 300 Steam Boiler is manufactured to exceed ASME Section IV standards and typically is used to provide operating pressure of up to 15 psi with nominal operating temperature of 218°F to 240°F.

These vessels contain 37 vertical firetubes, each of which is 1˝" diameter, each fitted with a high-efficiency turbulator for maximum heat transfer. The combustion chamber is fully water-backed, with burners that are UL listed.

This boiler qualifies as a Category I gas appliance with industry standard controls wired to NEC specifications.

Safety: A well-made, heavy vessel is naturally a safer boiler. But TRIAD Boilers also have a firebox design that is completely backed by water, along with extra safety controls on the boiler that results in a very safe and secure package.

Standard Features: The following standard features include nationally known parts and controls that are available at most supply houses, allowing for quick and easy repair and maintenance, which can dramatically reduce down time:
