All-welded Plate Type Heat Exchanger

Product Catalog

Xenesys Inc., the worldwide leader in the OTEC power generation field, presents a totally new heat exchanger structure combining tube-type with plate-type

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, Ocean Thermal Energy Conversion.
Since they have an all welded structure, it is possible to use them under difficult operating conditions such as high temperature and pressure and with fluids that are not compatible with gaskets. The new concept of these heat exchangers is to combine the features of both tube-type, which is tough and used for wide range of applications, and plate-type, which is small and compact yet high performance.
By adopting our uniquely developed box structure(R), 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.

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. heat-transfer efficiency. Also, the occurrence and progression of scale contamination by stagnation will be inhibited due Downsizing reduces not only equipment initial cost but installation cost. to no flow reversal. Since the position and size of the nozzle can be set freely, unnecessary pressure loss at the fluid inlet / outlet can be minimized.

We manufacture a very wide range of heat exchangers with a size of 5 to 450 m2 from 2000 ton small press and mold. Combining the length and the number of the heat transfer plates enables us to design flow velocity of fluid for determining heat transfer performance, and by combining with the degree of freedom of Maintenance Cost Savings 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.
