CFR 1500-3000

The World’s First Stainless Steel Condensing Boiler That Can Be Installed in a Category I Vent.

Building on AERCO’s industry leadership and decades of experience, CFR is engineered to enable building owners and facility managers to cost-effectively upgrade their boiler plant and maximize performance while safely reusing existing Category I / Type B venting.

All CFR models are complemented with AERCO’s Edge® Controller to optimize system efficiency and operation, and easily integrate the CFR boiler with a facility-wide Energy Management or Building Automation System. Additionally, the advanced StackGuard™ Sensor helps ensure safe operation in Category I / Type B venting systems by monitoring flue gas temperature and signaling the controls to adjust firing rates as needed to stay above the dew point, effectively preventing condensation-related issues. This makes CFR a perfect retrofit solution in buildings striving for best-in-class system performance and operational excellence.

Features and Benefits

Innovative Design for Efficiency and Cost Savings

CFR maintains dry flue gas while exceeding efficiency standards with up to 87.1% thermal efficiency to help comply with local energy conservation mandates. The CFR boilers are able to achieve this performance while safely reusing existing Category I / Type B venting for a cost-friendly solution in retrofit projects. The StackGuard Sensor helps ensure dry operation by monitoring flue temperature and preventing condensation, supporting long-term system reliability. CFR also delivers the highest turndown in a Category I boiler to match energy input directly to fluctuating system loads and yield the highest possible seasonal efficiencies.

Superior Construction for Greater Uptime Reliability

The durable 439 stainless steel heat exchanger in the CFR boilers make them highly resilient to condensation. It is backed by industry-leading warranty, including against condensate corrosion. The result is greater uptime reliability in all system applications, regardless of design return water temperatures and reset schedules. The fire-tube heat exchanger design is built to withstand thermal shock and to allow various piping configurations, including variable-primary, making it the ideal for a wide range of commercial applications. Secondary and bypass pumps – typically crucial to the operation of traditional boilers – are not required. It makes CFR the perfect drop-in replacement for retrofit projects to save time and money on installation.

Saves Space, Easy to Install and Service

A compact footprint enables facilities to maximize the use of their valuable mechanical room space, and it can be easily maneuvered into retrofit installations with no need to tear down walls, use cranes or other expensive equipment. CFR boilers fit through a standard 36" doorway and can travel via freight elevators. It can be serviced via the front or top as well as the side for zero side clearance installation between two units for additional space savings.

Boiler Sequencing Technology (BST)

It requires less energy for a group of modulating boilers, each firing at “part load,” to heat a building, than for a single boiler operating at “full fire” to carry the entire workload. To meet building demand, the BST will employ as many boilers as available, each operating at its most efficient firing rate. Importantly, because the BST reacts in real-time to, up to 16 boilers, changes in the number of boilers available, users can take a unit offline for maintenance at any time or bring on back-up boilers for extremely cold conditions without changes to the BST. And as individual boilers are added or deleted, the energy delivered is automatically adjusted to prevent fluctuations in the header temperature of the plant.
