All-welded Plate Type Heat Exchanger “XP Series”
XP Series are all-welded plate type heat
exchangers with our unique heat transfer pattern and flow structure.
Our heat exchangers have both the distinctive features of plate type heat exchangers (high performance and compactness) and also similar characteristics to the shell and tube type (high pressure resistance).
The XP series technology has been advanced through the research and development of Ocean Thermal Energy Conversion systems.
XP plate type heat exchangers can be applied to not only power generation but to various industrial uses such as pre-heaters, coolers, condensers, etc.
- Low-pressure Loss / High Heat Transfer Efficiency
The XP Series has a unique plate pattern and structure that decreases unnecessary turbulence of flow, which does not relate to heat transfer performance and actualized low-pressure loss. The pressure loss of the XP Series is smaller than general purpose PHEs under the same flow rate conditions, this makes it possible to design for faster flow than general purpose PHEs and still fulfill the specified allowable pressure loss.
Compared to other heat exchangers such as the shell and tube type, the heat transfer performance of the XP Series is very high, allowing for overwhelming compactness.
- Space Saving
The XP Series heat exchangers are extremely compact compared with general purpose PHEs and shell and tube type heat exchangers under the same operating conditions, which saves on installation space.
For example, compared to shell and tube type heat exchangers, the heat transfer performance is drastically improved. When applying XP Series you can expect not only space savings but also reductions in construction, plumbing, and maintenance costs. Xenesys has an established history of reducing the number of required units for its customers.
- High Pressure Resistance and Maintenance
XP Series are joined by welding heat transfer plates so that there is no leakage of fluid under high-pressure conditions such as 4MPa. The XP Series combines characteristics of PHEs and shell and tube type heat exchangers. As for maintenance, there is no need for large-scale gasket replacement, but only cleaning by chemical solution and high-pressure washing. Workloads such as fieldstripping, plate cleaning, reassembly will be decreased dramatically and parts replacement cost will be almost negligible.
・High Flexibility in Heat Transfer Plates.
Through our unique press technology we can offer eight (8) different plate sizes from small to large in the same heat-transfer pattern.
・Low Pinch Temperature
Compared with tube and shell type heat exchangers, pinch temperature is low. Profitability will improve through the increase in the amount of evaporation and condensation or the increase in the production of chemicals under the same operating conditions.
Pressure loss in the heat exchanger will be reduced (by approximately 1/3 compared to general purpose PHEs), so lower power pumps can be utilized.
・ Services for Design and Evaluation
At Xenesys we maintain our own experimental equipment such as boilers, refrigerators, etc, and at the Imari Plant we have performed in-house performance tests for the XP series under various conditions. Utilizing our equipment, we can offer performance confirmation tests and performance evaluation services conducted under conditions simulating your working environment.
