Discharge capacity
(for all four models, for hot condensate)
2.5 Function
■
Due to the gravity the condensate fl ows downwards to the lowest point, which is the condensate trap housing. In the
lowest position of the fl oat the outlet cross-section is close. Rising of the liquid level lifts the fl oat and opens the outlet.
Condensate will be discharged through the upturned immersion tube. Decreasing condensate level closes the outlet again.
2.6
Compensation line
■
In order to get proper function, the non-condensable gas must be able to leave the housing. Due to the vertical installation,
the non-condensable gas is able to leave the housing and fl ows into the steam/gas chamber above it, which has the same
pressure level. If the self-venting through the pipe must be extended, the control screw (4) can be replaced by a cutting ring
screw bolt and a compensation line can be installed leading upwards.
2.7
Automatic venting
■
In the case of steam applications, automatic venting must be provided (vent jet).
2.8
Gastight under-level fl oat control (only for gas applications)
■
For gas applications, a gastight under-level fl oat control is nearly exclusively used. Consult with Rifox, if necessary.

For Model WO-1111 and EF-1112
For Model WO-1111-N and EF-1112-N:
For the cold condensate the discharge capacity is
higher because of medium temperature and density.
For the hot condensate the discharge capacity is
lower because of medium temperature and density.
