The XE Vertical heat Exchanger is a revolutionary steam control system designed for implementation in larger facilities that depend on Steam/Water heating systems. Its unique characteristics reduce greenhouse emissions because the system consumes less fuel and reduces the wasteful emission of flash steam. It also reduces operation costs and facility carbon footprint, while boasting a lower installation cost than other systems currently being installed.
The XE steam exchanger systems are available in multiple sizes:
Units can be duplexed for higher capacity and redundancy. High efficiency operation on steam pressures up to 175 psig.
The XE design extracts extra energy from condensate by using the lower part of the heat exchanger as a water to water exchanger. This simple design also eliminates the wasteful flash steam venting that is typical of other designs because of the lower outbound condensate temperature.
In this simplified diagram, straight 100 psi steam fills the unit, except for the bottom 20 percent. The condensate there is being cooled by the entering 160F return water. The unit is sized to cool the condensate to 200F, so it doesn’t flash.
The primary control valve is at the bottom of the heat exchanger, and adjusts the amount of flooding to meet the heat demand. Often times a pump is not needed to lift the condensate, because unlike a modulated steam unit, 100 psi is pushing the condensate.
The major difference between conventional and XE designs is the use of a control valve on the outlet that allows condensate to flood the lower portion of the heat exchanger.
