All-welded Plate Type Heat Exchanger“XP Series”
XP Series are all-welded plate type heat exchanger.
It is compact comparing with shell & tube type and endures high pressure comparing
with gasket type PHE.
No need for complicated gasket replacement work between the plates.
It is developed and commercialized applying for the knowledge and technique skilled
by research and development of Ocean Thermal Energy Conversion system.
It can be applied to not only power generation use but also various industrial uses.
- Low Pressure Loss / High Heat Transfer Efficiency
XP Series achieved low pressure loss, due to plate pattern and structure to decrease the unnecessary flow turbulence that does not relate with heat transfer performance. Thus, it enables to apply to high flow velocity, and furthermore, down-size the heat transfer area by high heat transfer performance.
- Space Saving
XP series are remarkably compact and saves installation space compared to shell & tube type and gasket type PHE. (Under the same operating conditions) Compared to shell & tube type, performance will advance remarkably, so it is not only space saving but also number of heat exchangers needed will be reduced drastically in some cases. In that case, construction cost and facility maintenance cost will be reduced drastically.
- High Pressure Resistance and Maintenance
All-welded (Fully-welded) structure ensures no leakage of liquid, gas, or any fluids even under high pressure conditions such as 4MPa. The maintenance cost associated with gasket replacement can be reduced significantly, for gaskets are not used between the plates in our PHEs. To clean inside of our PHEs, we offer to use CIP equipment and special chemical solution.
・High flexibility in plate size
We can offer different sizes, from small to large, of various heat transfer plates, by means of our patented press
・ Pinch temperature is small
Compared with tube & shell type, pinch temperature is low. Profitability will improve by the increase of amount
of evaporation and condensation and the increase of the production such as chemicals, under the same operating
・ Downsizing the pumps
Pressure loss is about 2/3 of that of conventional PHE, so it is possible to downsize and reduce the volume
of adopting pump.
・ Services for designing and evaluation
We can offer technical services such as performance confirmation test, simulating special circumstances.
Please do not hesitate to consult us.
