Condensate discharge through float drain
Float drains are mechanical condensate drains that work automatically as they are closed and opened based on the buoyancy of a float body. When the condensate in the vessel rises to a certain level, buoyant force pushes the float body up and opens the outlet channel for the condensate. The float body closes again when the condensate drops to below a certain level. A small amount of condensate remains in the vessel.
Two different float drains are used for discharging the condensate:
• Open when pressureless ([NO] normally open) – at operating pressure ≤ 0.5 bar(g) the float drain opens
• Closed when pressureless ([NC] normally closed) – the float drain remains closed even at operating pressure 0 bar(g)
Both types of drain are delivered with the position >>Automatic discharge<< from the factory. The knurled screw is screwed downwards as far as it will go. To test the discharge function or relieve the pressure on the filter during maintenance work, the float drain can be set to the position >>mechanically open<<. Screw the knurled screw anti-clockwise (left-hand thread) upwards as far as it will go.
