Shopping for a new heat exchanger? You have come to
the right place. Here you can learn about the different types of
exchangers and then order one by
calling one of the many reviewed manufacturers and retailers of heat
exchangers.
Electric Pump Package
As steam enters the exchanger, there will always be a positive pressure
on the inlet side of the trap, allowing condensate to flow through to
the pump receiver. If a vacuum should arise inside the exchanger, then
the vacuum breaker will remove the vacuum by introducing atmospheric air
into the exchanger. With the steam trap installed 15" below the
exchanger, this will give a 1/2 psi hydraulic head before the trap,
creating the differential pressure required to drain condensate from the
exchanger.
Electric condensate pumps offer a number of advantages that often make them the preferred choice among engineers: Engineers are familiar with their operation and ease of maintenance. There are many different options available to meet custom requirements
o Iron or steel receivers are available
o Relatively small units with low profile equate to smaller required installation space
o A wide range of sizes are available,
catering to diverse applications
o They can deliver large capacities over wide ranges of back pressures
o They can accept condensate flow during the pumping cycle.
