The ZFR is known for its high efficiency at each output stage. Combining with an integrated economiser further increases the efficiency. An optional condensing heat exchanger for the residual waste heat also reduces the fuel demand. Extremely low emissions (to below 50 mg NOx) are possible thanks to the large furnace.
