1, the whole structure of integration, high heat exchanger with double pipe casing technology (B type machine), in improving heat efficiency at the same time, eliminate the effects of scale.
2, gas valve USES the new double safety protection device, regardless of any fault all can ensure that the gas shutoff, the piecewise ignition technology, effectively preventing the ignition deflagration phenomenon occurs, digital micro process control gas proportional valve control, according to the working state intelligent judgment gas demand, minimum temperature control in 6 ℃ (8 kg/min) the following, save the operation cost.
