Condensate Return Stations<br />
Description<br />
The condensate recovery units are designed to handle hot<br />
condensate, which is commonly returned for use as boiler<br />
feedwater. They can handle high quantities at 98°C with<br />
pump delivery heads up to 30 - 35 meters. A unit comprises<br />
three main parts - receiver, pump/pumps and control panel.<br />
Standards<br />
This product fully complies with the requirements of the<br />
European Machinery Directive 98/37/EC, European Low<br />
Voltage Directive 72 / 73 / EEC and European Electromagnetic<br />
Compatibility Devices Directive 89/336/ EEC.<br />
This product is not a pressurized vessel and therefore<br />
does not need to comply with the European Pressure<br />
Directive 97/23/EC.<br />
• Receivers are manufactured of mild steel or SS<br />
304/316. All sizes are fitted with adequately sized vent,<br />
overflow, drain and inlet connections flanged to PN16 or<br />
screwed. A water level gauge and control is provided.<br />
• Pumps are designed for operation under conditions of<br />
low NPSH to handle hot condensate with the minimum<br />
of flooded suction. They are directly coupled to motors<br />
having class F insulation (class B temperature rise) and<br />
motor enclosure rating IP54 minimum.<br />
• Control: Receivers are fitted with solid state level<br />
control’s which provides on / off cascade pump operation.<br />
The control panel incorporates electrical equipment<br />
suitable for 400 volt, 3 phase, 50 Hz, 4 wire supply.<br />
Control equipment is installed in a pre-wired IP54 rated<br />
metal enclosure. Connections for BMS interface are<br />
provided to monitor pump run or tripped condition.<br />
• Pump fitting: The motor and pumps are mounted<br />
under the receiver with over size suction inlet pipework<br />
and isolation valves. The pump discharge outlet is fitted<br />
with a non return valve and a pressure gauge.<br />

Pressure Reducing Stations<br />
It is more efficient and economic to<br />
produce steam at high pressures<br />
ready for delivery through the distribution<br />
system. This may mean that the<br />
pressure needs to be reduced prior to<br />
the point of use or for different parts<br />
of the system. A reliable method of<br />
providing pressure reduction is to use<br />
a pilot operated pressure reducing<br />
valve station.<br />
Every pressure reducing station is<br />
custom designed according to<br />
required steam flows and pressures.<br />
