A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler.[1] The narrow-tube construction, without any large-diameter drums or tanks, means that they are safe from the effects of explosion,[note 1] even if worked at high pressures.[2] The pump flowrate is adjustable, according to the quantity of steam required at that time. The burner output is throttled to maintain a constant working temperature. The burner output required varies according to the quantity of water being evaporated: this can be either adjusted by open-loop control according to the pump throughput, or by a closed-loop control to maintain the measured temperature

Our pure steam generator has the capacity ranging from 50-100-200 to 300 Kg/Hr. They are used for producing pure pyrogen free sterile steam.
