Mixture of LPG and Air Interchangeable to Natural Gas

This fully redundant installation has been achieved firstly by using two "VMG" mixing units in parallel, each one sized for the maximum consumption. This way, one unit is always available as full backup. Secondly, in regards to the control system, a redundant PLC configuration (certified back-up system) manages the automatic swap of the units in case of fault. Besides, a dual AC / DC Power Supply , with backup battery, prevents the halt of the units in case of power fault or loss of energy. Furthermore, so as to meet the furnace requirements, the plant is also equipped with an automatic control system of the Wobbe Index, which may adjust the mixture composition in order to guarantee its accuracy and stability.
