Series 900 Space Heater Boilers - Power Burner

Overview: The Series 900 is a complete UL listed package that is a ready-to-install system featuring a perfectly matched powerful and efficient burner and boiler combination. All necessary boiler controls and secondary plumbing are in place and pre wired, and the vessels easily fit through a 32" doorway, resulting in a very quick start-up.

Firing rates for the Series 900 are available from 600,000 Btu/hr to 1,000,000 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 900 is manufactured to exceed ASME Section IV standards and will typically provide temperatures of between 130-210°F for space heating or process water applications. The vessel capacity is 75 gallons with a heating surface of 78 sq. ft.

These vessels feature 73 vertical firetubes, each of which is 1½" diameter and fitted with a high-efficiency turbulator for maximum heat transfer. The combustion chamber is fully water-backed, with burners that are UL listed.

The 900 Series 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:
