Decarbonization Without Compromise
Sequoia boilers are purpose-built for organizations committed to reducing their carbon footprint. By eliminating combustion, these systems remove Scope 1 emissions entirely: no fuel storage, no flue gases, and no local pollutants. This makes them ideal for facilities pursuing LEED certification, ESG compliance, or net-zero targets.
Whether you're electrifying a new hospital, retrofitting a university campus, or modernizing a manufacturing plant, Sequoia’s zero-emission performance supports your long-term sustainability strategy. With no need for fuel delivery infrastructure or emissions control systems, installation is faster and cleaner. These boilers are especially well-suited for healthcare, education, and food processing sectors where clean, quiet, and safe operation is essential.
High Voltage, High Performance
All Sequoia models operate directly at medium-voltage distribution levels (4.16–25 kV), eliminating the need for step-down transformers and reducing installation complexity. This direct-to-distribution compatibility not only lowers capital costs but also improves energy efficiency by minimizing transmission losses.
Whether you’re powering a district energy plant, a pharmaceutical production line, or a large-scale hospitality facility, Sequoia delivers consistent, high-capacity output with minimal infrastructure. The Sequoia J, for example, can produce up to 270,000 lb/hr of steam at pressures up to 500 psig, making it ideal for heavy industrial and process steam applications.
Rapid Response, Reliable Output
Sequoia boilers are engineered for responsiveness. From hot standby, they can reach full output in about one minute—making them ideal for peak load management, backup systems, or facilities with fluctuating demand. The 10:1 turndown ratio allows precise modulation from 10% to 100% capacity, ensuring energy is only used when needed.
This is especially valuable in applications like district heating, campus-wide energy systems, and industrial processes where demand can vary significantly throughout the day. With automatic load tracking and real-time control, Sequoia ensures stable, efficient performance under all conditions.
Safe by Design
Safety is built into every Sequoia model. With no flames, fuel, or combustion risks, these boilers offer a fundamentally safer operating environment. Integrated protections include low-water cutoffs, pressure relief valves, and grounded pressure vessels. Electrode technology ensures that current cannot flow without water, eliminating the risk of dry firing. The intuitive PLC/HMI control system provides real-time monitoring and diagnostics, making it easy for operators to manage performance and respond to alerts. This makes Sequoia ideal for mission-critical environments like hospitals, pharmaceutical plants, and food production facilities where safety and uptime are paramount.
Minimal Maintenance, Maximum Uptime
Sequoia boilers are designed for long-term reliability with minimal maintenance. Unlike traditional combustion systems, there are no burners, fuel lines, or flue components to service.
The immersed and jet-type electrode designs reduce moving parts and eliminate fuel residue buildup. Long-life electrodes are continuously cooled by internal water circulation, extending service intervals and reducing wear.
This makes Sequoia ideal for facilities with limited maintenance staff or those seeking to reduce operational costs—such as universities, data centers, and industrial plants with 24/7 uptime requirements.
