Each chamber has a submerge tube heater at the bottom, and one condenser on the second chamber. The generated steam on the first chamber is used to warm-up the second stage heater. The condensation produced inside the heater tubes is recovered via one steam trap by the distillate water pump.
Distilling plants were designed to operate with waste heat from diesel engines jacket cooling water, any how the units can operate with other heat sources, like steam or combination of both systems. The distillate water produced is a very high quality product with salt content in distillate less than 2ppm.of NaCl.
