All welded Plate Type Heat Exchanger “ XP Plate” Merit
“XP Plate” are all welded plate type heat exchangers that do not need gaskets and
were uniquely developed in aiming for the realization of the ultimate renewable Energy-Saving
energy, Ocean Thermal Energy Conversion.
Newly developed for evaporation and condensation for small temperature difference
Since they have an all welded structure, it is possible to use them under difficult power generation, high performance and compact XP units can be installed in a small
operating conditions such as high temperature and pressure and with fluids that are space around distillation towers. It works with the thermosiphone method for its
not compatible with gaskets. The new concept of these heat exchangers is to simple one-path flow and low pressure loss. We can provide high level design from
combine the features of both tube-type, which is tough and used for wide range of extensive experiment data accumulated over many years.
applications, and plate-type, which is small and compact yet high performance.
By adopting our uniquely developed box structure ®, the inlet and outlet of the fluid
can be set to the optimum size according to the volume of the fluid at a desired
position, realizing a simple and ideal streamline completely different from
conventional products. This makes it possible to use fluids that have been difficult
to use, such as fluids which clog due to contained solids, highly viscous fluids, and
gas bodies that have large volumes and high flow rates.
Flow structure completely different from conventional products
Space Saving and Cost Savings
We resolved a problem in the conventional plate-type heat exchanges where narrow parts caused clogging and pressure
loss. By lining rectangle-shaped long heat transfer plates vertically, we can achieve a simple counter flow and the best Significant space saving can be achieved by utilizing XPs compact characteristics.

to no flow reversal. Since the position and size of the nozzle can be set freely, unnecessary pressure loss at the fluid inlet

the nozzle layout, various kinds of heat exchangers having various flow patterns can be provided.
Compared with tube-type, the “wall shear force” of the plate-type is larger, which reduces contamination. “Wall shear force”
is comparable to a “self-cleaning action.” The force the heat-transfer surface receives from the passing fluid prevents the
plate from becoming contaminated.
XP plate can be designed for a higher flow rate than other products under allowable pressure loss conditions. XP plate’s
structure is optimum for this innovation in technology; increasing the speed of the fluid to increase the "wall shear
force“ allows the "self-cleaning action" and will extend maintenance intervals to the maximum.
