The C1X Condensing Economizer saves fuel by preheating virtually any cool liquid stream (makeup water, wash water, hot water preheating, process, etc.) by capturing waste heat from a boiler stack. The unit has individual fin tubes compression-fitted to the liquid manifold for ease of tube replacement requiring no welding. It increases the amount of heat recovered by capturing both sensible and latent heat. The internal gas bypass can be used to maintain water temperature when too much heat is available.

- Condenses on natural gas only
The C2X two-stage Condensing Economizer is a condensing economizer that captures heat through both a traditional stack economizer section and a condensing section. Can be utilized on boilers up to 2,500 HP. The non-condensing section of the economizer recovers energy by preheating the boiler feedwater. The condensing section preheats virtually any cool liquid stream (makeup water, wash water, hot water preheating, etc.), and the control system maximizes condensing when firing natural gas, then automatically switches to a near-condensing mode when firing #2 oil (if applicable). The condensing section allows the latent heat to be reclaimed from the flue gasses, achieving the highest possible efficiencies. The upper coil, lower coil, modulating valves, control system, and other system components are sized as a system to deliver the maximum possible cost savings.
- Up to 94% efficiency
- Two-stage condensing economizer
- Available for 100 to 800 HP boilers
- Firetube or flextube steam boiler applications
- Can preheat large volumes of process hot water
New technology exclusive to Cleaver-Brooks enables the C2X-HE to be the first two-stage condensing economizer in the industry to achieve up to 94% efficiency. It is smaller and lighter than current two-stage economizer models and is ideal for high-percentage makeup water or process hot water applications. The C2X-HE is the first two-stage condensing economizer to achieve up to 94% efficiency. Every 1% increase in efficiency correlates to a 1% reduction in emissions, so the C2X-HE helps meet both efficiency and emissions reduction goals.

- Up to 87% boiler efficiency
- Virtually maintenance free
The ClearFire Economizer (ECF) is ideally suited for applications utilizing the horizontal CFH firetube or the vertical tubeless CBT model. Efficiency gains can reach 3-5% depending on the feedwater return temperature. The Integral economizer is available for high pressure steam CFH applications or the external economizer can be used in low pressure CFH or CBT needs.
