Vertical Shell in opposite directions. These are used for liquid-liquid, condensing and gas cooling applications. Units are usually mounted vertically when condensing vapour and mounted horizontally when handling high concentrations of solids.
Vertical Shell is in spiral flow and the other in a cross flow. Vertical Shell passages are welded at each side for this type of spiral heat exchanger.
Vertical Shell can be used for liquid-liquid applications if one liquid has a considerably greater flow rate than the other. Vertical Shell design is that of a condenser, and is usually mounted vertically.
Vertical Shell type of flow is suitable for handling low density gas, which passes through the cross flow, avoiding pressure loss.It is designed to cater for the sub-cooling of both condensate and non-condensables. The coolant moves in a spiral and leaves via the top. Hot gases that enter leave as condensate via the bottom outlet.
