High Pressure Control: It all the gas generated cannot be drawn in by the compressor and passed on the filling manifold, either due to low capacity of the compressor or fast generation, gas pressure will gradually build in the generator. When the gas pressure reaches a predetermined level (about 0.5 kg/cm2) carbide charging will be cut off automatically and further generation of gas is stopped. There is no expensive gas holder with the KVK Acetylene Generator. This item alone will reduce the investment on such a plant. Further, as the gas generated is always at a positive pressure, the pumping cost is also reduced. Since the generator is constantly at a positive pressure, (once the plat has been purged with Nitrogen) no air can enter the system, and it is this feature which makes the "KVK" Plant inherently very safe.
