Description
Condensate
Discharge
Unit
1
PowerTrap
Removes steam condensate
consumed by the heat
exchanger to produce hot water.
・
The PowerTrap has both a
steam trap function, and a
pump function for discharging
condensate even when there is
very little pressure from the
heat exchanger side.
・
The silencing bush reduces the
sound of water hammer
generated by flash steam and
cold condensate in contact.

Blowdown Valve
Heat Exchanger
Unit
6
Heat Exchanger
Produces hot water by
exchanging heat from steam
supplied by the steam supply
unit to water.
・
The flow sensor stops supplying
steam when the water flow rate
becomes equal to or lower than
the controllable flow rate.

Steam Inlet Valve
Supplies the required amount
of dry steam for the water
temperature to become the set
temperature.
・
Two types of control valves are
available, pneumatic or electric.
(Electric type: Air supply is not
necessary, control response is
delayed compared to
pneumatic type).
・
Separator incorporated in the
control valve separates and
removes condensate in the
steam piping.

Receiver Unit
12
Condensate Receiver
Stores steam condensate
temporarily while the
PowerTrap
discharges condensate.
・
The air vent for steam removes
air in the steam piping during
initial operation.

Pressure Reducing
Valve
Supplies motive steam to the
PowerTrap for the pump
operation.
・
Pressure reducing valve (15)
adjusts the pressure of the
motive steam for the PowerTrap.
・
Pressure gauge (19) indicates
the source pressure of the
steam.
・
Pressure gauge (20) indicates
the steam pressure to be
supplied to the PowerTrap.
