Gestra KH Steam-Powered Condensate-Return Unit
BRAND : Gestra
Description
The condensate flows into the upright cylindrical tank, displacing the air through a solenoid valve. The tank is equipped with the compact level system type NRGS 11-1 / NRGS 16-1. As soon as the water level reaches the upper electrode tip the solenoid valve in the vent line is closed and simultaneously the solenoid valve in the booster-steam line (introduced from above into the tank) is opened. The flowing steam pushes the condensate via the condensate main into the condensate tank. The condensate level sinks and when the lower electrode tip emerges, the solenoid valve in the booster-steam line is closed and the solenoid valve in the vent line opened. The cycle repeats itself. Before entering the condensate-return unit the condensate is collected in a condensate header to be provided on site. This condensate header should be equipped with a vent. Condensate inlet and outlet are provided with GESTRA DISCO non-return valves type RK. The condensate-return unit is equipped with a pressure-gauge and the booster-steam line with a stop valve with characterized valve cone which permits the adjustment of the booster-steam pressure in accordance with the length of the condensate discharge line and the prevailing back pressure. As the condensate-return unit operates without a float it is unaffected by waterhammer. Continuous drainage of the booster-steam line upstream of the solenoid valve is ensured by a GESTRA steam trap.

Description
The condensate flows into the upright cylindrical tank,
displacing the air through a solenoid valve.
The tank is equipped with the compact level system type NRGS
11-1 / NRGS 16-1. As soon as the water level reaches the
upper electrode tip the solenoid valve in the vent line is closed
and simultaneously the solenoid valve in the booster-steam
line (introduced from above into the tank) is opened. The
flowing steam pushes the condensate via the condensate
main into the condensate tank. The condensate level sinks
and when the lower electrode tip emerges, the solenoid valve
in the booster-steam line is closed and the solenoid valve in
the vent line opened. The cycle repeats itself.
Before entering the condensate-return unit the condensate
is collected in a condensate header to be provided on site.
This condensate header should be equipped with a vent.
Condensate inlet and outlet are provided with GESTRA DISCO
non-return valves type RK. The condensate-return unit is
equipped with a pressure-gauge and the booster-steam line
with a stop valve with characterized valve cone which permits
the adjustment of the booster-steam pressure in accordance
with the length of the condensate discharge line and the
prevailing back pressure.
As the condensate-return unit operates without a float it is
unaffected by waterhammer.
Continuous drainage of the booster-steam line upstream
of the solenoid valve is ensured by a GESTRA steam trap.
The steam traps, non-return valves and compact systems
are described in separate data sheets.
