The Proforte Flameless Regenerative Thermal Oxidizer (FRTO)
Because it doesn’t use a burner, our FRTO system is able to clean the exhaust from coffee roasters, limiting as much as possible the generation of harmful CO2 and NOx emissions. It operates at a high degree of thermal efficiency (95–98%), allowing coffee production plants to meet current and future environmental code requirements.
MILLENNIUM® Regenerative Thermal Oxidizer (RTO)
Designed by MEGTEC, this fully integrated RTO reduces natural gas consumption by up to 18% over conventional RTOs. It maintains destruction efficiencies up to 99% and minimizes fuel costs by achieving 95–97% thermal efficiency. In addition to these LEED-qualifying benefits, it also features forward programming that automatically adjusts for flow changes, and its heated recirculation system helps prevent condensation during the quench cycle.
Our thermal exhaust air-cleaning systems are ideal for coffee roasters with a batch capacity of up to 725 lbs. per hour, particularly our P, G and R Series models. Their combustion chambers minimize emissions and promote up to 95% efficiency in destroying pollutants associated with the roasting process, such as VOCs, COs and particulate matter. The upright design features a maintenance-free outer shell and can accommodate optional stacks.
Designed for larger commercial roasters (both recirculating and non-recirculating), our catalytic oxidizers operate at low temperatures to reduce emissions and energy consumption. The low-temperature catalytic bed (metallic or ceramic) removes all coffee-specific odors and can be coated in platinum and / or palladium for optimal performance. These high-efficiency catalytic oxidizers achieve 95% destruction efficiency of VOCs and other pollutants.
Green Coffee Pre-heating
With our green coffee pre-heating process, you can decrease energy use and emissions and increase your hourly capacity by over 20% without diminishing your coffee’s flavor. This specially designed heat recovery technology uses the energy present in the exhaust from your previous roast to pre-heat your next batch, effectively shortening the drying period before the Maillard reaction begins.
