Functional description The steam generator Condair Sigma is a pressureless steam generator that utilizes an electrode heat- ing. The steam generator Condair Sigma is designed for SPA applications. Steam hose Steam distributor Condensate hose with siphon (if steam distributor is installed... - Page 13 Steam generation Any time steam is requested, the electrodes are supplied with voltage via main contactor. Simultaneously, the inlet valve opens and water enters the steam cylinder from the bottom via water cup and supply line. As soon as the electrodes come in contact with the water, current begins to flow between the electrodes, eventually heating and evaporating the water.
