Description
Condensate recovery and return station – Standard version
Application:
Industrial installations, processing technology, plant manufacturing, etc.
Scope of applications
The condensate recovery and return station is used in steam systems and serves to return the accruing condensate for reuse.
The ARI condensate station is a compact installation premounted on a base frame and consists of high-quality individual components. The individual components of the centrifugal pump (shaft, impellers, distributors) are made of high-quality CrNi steel.
Recirculation protection is ensured through the installation of non-return valves. Maintenance in the operating status is enabled by stop valves installed upstream and downstream from the pumps.
Venting the receiver to the atmosphere ensures that the condensate feed is not hindered by back-pressure in the collecting tank. The temperature display is attached directly to the receiver (max. system temperature 95°C). The pumps are fitted on the pressure side with a control pressure gauge.
Operating principles
As it accrues the condensate is collected in the receiver of the condensate recovery and return station until a preset maximum level in the receiver is reached.
If the preset maximum level is exceeded one of the installed recirculating pumps comes into operation.
The condensate is pumped off until the minimum level required by the system is reached.
Pump controller (optional)
The pump controller works discontinuously.
This minimizes operating hours and energy consumption.
The switching instants (pump(s) on / pump(s) off / low water and high water alarm) are
preset.
The following signals and switches are integrated in the controller:
– Pump On / Off
– High water alarm (overflow)
– Low water alarm (water shortage)
The controller contains:
– Optical operating and fault displays for the pump(s)
– Operating device for manual / off / automatic mode on the control cabinet
– Regular, automatic lead pump changeover (if 2 pumps are used)
See the annex for the pump controller’s technical data “wiring diagram”
Level measuring as well (optional)
The level in the receiver is visualised by means of a sensor in the display.
Safety devices
The condensate station is designed for use with atmospheric pressure.
A vent to the atmosphere protects against operations with non-permissible pressure (vapour pipe).
