Shipbuilding Industry steam heater oil cooler plate heat exchanger plates gaskets EPDM/NBR material DX20DM
Plate Heat Exchanger Construction
The main principle of plate type heat exchangers(PHEs) is to allow the cross-flow of two fluids over a larger surface area. Plate heat exchangers have high thermal efficiency since the hot fluid flows downwards and the cold fluid flows upwards over large exposed plates. Compared to a typical tube type heat exchanger, a PHE has serveral times higher heat transfer efficiency due to cross-flow and the corrugations in the the plates increase turbulence and reduce the Reynolds number(Re).

Plate Heat Exchanger Features
(1) High Heat Transfer Coefficients
MC Plate Heat Exchangers provide high rates of heat transfer, due to the turbulence inducing shape of the plates. The special gasket configuration of the plates prevents any mixing of the media being processed. In the port area both fluids are separated by double gaskets. Additional safety is ensured by the leakage gap.
(2) Saving the installation space
Since the heat transfer efficiency is high, only 2-30% installation space is required comparing to the same capacity of the multi-tubular heat exchanger.
(3) Low contamination
Strong turbulent flow formed by the bump in flow way and short staying time of the fluid inside the heat exchanger will result in getting the effect to avoid scale adhesion.
Convenient disassembling and assembling. Cleaning is easy to handle the contamination in an efficient way.
(4) Minimum heat loss
Heat is emitted in the side of the plate type heat exchanger and because the space is not much required the heat loss can be minimized due to less heat generation volume even when insulation or heat insulating materials are not used.
(5) Applicability & standardization
All the components or parts are standardized and the compatiblility of the parts is good. Plate number can be increased or decreased depending on the change of the capacity. Cleaning or replacement is easy when the plate or gasket is worn out.
