The new design is available across all ST Series models, including 6-inch, 8-inch, 10-inch, and 12-inch shell sizes, providing engineers and contractors with more flexibility when designing high-demand domestic hot water systems.
The boiler is designed for mission-critical facilities, including hospitals, healthcare campuses, military installations, data centers, laboratories and industrial plants.
The unit incorporates a three-pass fire-tube heat exchanger with 316L stainless steel condensing surfaces and full-penetration tube welds for long-term durability.
The NBT-400 is compatible with floor-mounted or wall-hung condensing appliances, including furnaces and tankless water heaters rated up to 400 MBH (3 GPH).
HyperPure combines rigidity and flexibility, allowing it to uncoil easily, hold its position during installation and bend at a radius of five times its outside diameter.
