Odorization machine is mainly used in the natural gas odorant added to the gas system, trace amounts of liquid odorant. Odorization machine is fully enclosed work, according to the gas flow proportional changes raise. I produced the odorant machine odorant concentration uniform odorant is tetrahydrothiophene (THT). All stainless steel precision metering pumps, storage tanks. When adding odorant ensure continuous, stable, accurate amount; using plc control, finished text display, free to set the parameters and work; a good man - machine interface; good sealing performance, no leakage; the whole device is integrated in the cabinet, Installation is simple, can be placed directly on the ground level. Products are divided into 200 liters storage tanks single, double pump optional 60 liters storage tanks single, double pump optional.
