Access the technical benchmarks and proprietary design features that drive 99% efficiency, variable-flow stability, and multi-fuel flexibility.
These technical resources provide clear, practical reference material to support boiler selection, system design, and long-term performance decisions.
(LDX 2101)
Duplex has a dual-phase microstructure (austenite and ferrite). This combination offers 2x the yield strength of 316L and significantly higher resistance to Chloride Stress Corrosion Cracking (CSCC).
In systems with unpredictable water chemistry or high chloride content, Duplex prevents the pitting and "localized" corrosion that leads to premature vessel failure in thinner-grade stainless boilers.
| Failure Level | Typical Cost Range |
|---|---|
| Local weld repair attempt | $4,000 – $12,000 |
| Tube bundle replacement | $18,000 – $45,000 |
| Full heat exchanger replacement | $25,000 – $60,000 |
| Full boiler replacement (300–800 MBH range) | $40,000 – $120,000+ |
| Emergency rental boiler during outage | $5,000 – $20,000 per month |
The large internal water volume provides thermal inertia. This prevents the "flash" heating and rapid cycling seen in low-mass water-tube boilers.
Ideal for Variable-Primary Flow systems. The boiler is immune to "low flow" trips, reducing the complexity of the control sequence and the cost of external piping.
It features separate connections for high-temperature and low-temperature return loops. By keeping the coldest water at the bottom of the vessel, it ensures the flue gases are cooled below the dew point more consistently.
This allows the boiler to stay in condensing mode even when high-temp loads (like DHW) are active, providing a 6% to 10% efficiency premium over boilers that blend return water.
The CFC-E utilizes a patented "tube-within-a-tube" design. An inner aluminum-alloy finned surface is die-fitted into a Duplex Stainless Steel tube. This creates an internal surface area 5x greater than standard smooth tubes and offers 10x the thermal conductivity of stainless steel alone.
Aluminum conducts heat 10x faster than stainless steel. This allows for maximum energy extraction from flue gases in a compact, low-pressure-drop fire-tube design.
Features a hinged front burner door and two rear access doors.
Technicians can perform a full fireside inspection and tube cleaning without disconnecting the burner, gas train, or venting. Cuts annual maintenance labor by 40% compared to "cabinet-style" boilers that require total partial disassembly for service.
The ClearFire-CE is engineered with proprietary Ember controls and a burner design that accommodates the higher flame speeds and differing energy densities of these fuels. This allows the unit to fire 100% RNG or up to a 20% Hydrogen-and-Natural-Gas blend without requiring physical burner modifications or field retrofits.
This "pre-certified" flexibility protects long-term investments from "stranded asset" risk as utility fuel streams evolve, while allowing facilities to meet immediate ESG goals by simply switching to sustainable fuel contracts.
