Product Structure
GPHE Advantage (Compare with Tubular Heat Exchanger)
Plate heat exchanger consists of a series of corrugated metal plates which have 4 holes in the corner used for two kinds of liquid channel through. The metal plates are fixed in the frame which have fixed and movable plate on both sides and tightened by stud bolts. The gaskets on the plates obstruct the liquid channel and leading liquids flowing through their own ways inter actively to exchange heat. The quantity and size of the plates are determined by liquid amount, physical medium, pressure and temperature o the flow. The corrugated plate is not only improving the turbulence extent of the 110w but also forming supporting points to reduce the pressure difference among medias. All plates are linked to the upper guide bar and positioned by the lower guide bar. Their ends are posed to the supporting lever. Because of high efficiency, space and energy effective, simple maintenance, etc.
GPHE Features | |||||
High Heat Transfer Efficiency | When the media flowing through the plates in a lower Reynold number, it can create turbulence, moreover, the smooth plates is not easy to generate scaling, so that the system has very high heat transfer efficiency in general water-to-water heat exchange process, this system’s heat transfer efficiency can achieve as high as 5000w/㎡.k which is higher than tubular heat exchanger by 204 times | ||||
Due to high exchanging efficiency, the heat transfer temperature can be very low, it’s best for lower-heat energy recycle. Generally, the heat recovering rate of plate heat exchanger is up to 90%. | |||||
For plates can be organized for different courses, plate heat exchanger could be designed to its optimal point and to flexibly suit the heat load changes without changing the frame, rest is only need to changing the plate number to suit new conditions, | |||||
Low retention volume due to the small channel, therefor plate heat exchanger is good at controlling the temperature and reduce the weight of the devices, especially for heat sensitive material processing. | |||||
The space occupied by plate heat exchanger is less than others. Under the same conditions, the space of plate heat exchanger is 1/3 or ¼ of tubular heat exchanger and it doesn’t need extra room during maintenance. | |||||
The plate can be cleaned in site, due to there is no dead end on it. The arrangement of course channel, the inlet and outlet of the eclectic media of heat exchanging fixed on the constant plate. This design is helpful cause no need to knock down the channel during cleaning. | |||||

Sealing Principle
Gasket is adhered to the corrugated plate, designed as double channels sealed structure, with telltale hole. When media let out from the first sealed channel, it will go through the telltale hole, then leak problem can be solved before media mixed.
Fixation and Seal
The clip-on gasket divided the fixation and seal function, so when seal function is not working, the seal function will not be
effected.

BPHE Installation, Operation and Maintenance
BPHE Installation
Plate heat exchanger should be fixed vertically. If chose horizontal or tilt installation, it will not just cause a toboggan of heat transfer efficiency, but also phenomenon of icing and blockage when the exchanger is refrigerating.
Plate heat exchanger products with small pieces(≤ 30 pcs) of model number B3-014, B3-015, B3-020, B3-026 can be fixed directly on the pipe, and large piece of the above on the vibration damper plate, or fixed by riveted bolts, panel beating, bracket and in other ways. If there is a shock, shockproof connection should be used.
Unless in special condition, it shall ensure hot side medium is fed from the top and discharged from the bottom and cold side medium is fed from the bottom and discharged from the top as the heat exchanger is connected with system to guarantee good heat convection and avoiding improper connection.
When plate heat exchanger is connected to pipe in brazing type, first you should clean up the surface, remove the grease, brush in chlorate(or silver soldering flux), insert the copper pipe into the connection, and braze with silver brazing with more than 45% silver. When jointing, aim the flames at the pipes, the highest temperature is not more than 650℃, and the jointing time of the same joint should not be too long. In order to prevent inner from oxidizing, nitrogen should be filled in the heat exchanger.
When plate exchanger larger than B3-095, is connected pipe is brazing type, a wet cloth should be wrapped up in the interface to avoid high temperature. In order to limit heating zone, there should be an angle at the range of the pipe and joint (normally an angle of 30°), using tig or mig. In order to prevent inner from oxidizing, nitrogen should be filled in the heat exchanger.
BPHE Operation and Maintenance
Anti prevent clogging If foreign matters enter into the channel of the heat exchanger or the channel is seriously scaled, the blockage for channel will appear, when being used as evaporator, it will cause freezing and used as condenser, it will cause corrosion; both will damage the structure of heat exchanger and result in inner leakage. So it need to pay attention to the pressure loss change of medium before and after passing through heat exchanger, if pressure loss increases suddenly, it shall shut down to clean and maintain the heat exchanger in time, if necessary, the heat exchanger shall be replated to avoid greater losses.
Icing prevention
A. Use antifreeze when the vaporizing temperature is close to the freezing point of one side of liquid.
B. Prevent too little overfilling of refrigerant resulting in over-lower vaporizing temperature
C. Clean and maintain it at routine interval to prevent icing arising from blocking resulted from the scaling in heat exchanger pipes
D. implement soft treatment for water with higher hardness so that the icing is avoided as the heat exchanger pipes is blocked as a result of scaling.
E. Mount drainage devices and carry out evacuation treatment for non-service heat exchanger in such way that the icing is avoided inside the heat exchanger in such way that the icing is avoided inside the heat exchanger when the ambient temperature is too lower.
F. Mount and use the filter screen its mesh less than 1mm in such way the floccus, filaments and bigger sundries are prevented to entering the heat exchanger and the icing is avoided as a result of blocking inside the heat exchanger.
G. Mount water flowing switch for the purpose of guarantee of constant water flowing pre-, middle- and post-operation of compressor in order to prevent the hydraulic pump against shutting down emergently accidentally during in-processing system.
H. Mount low-voltage protection control switch to prevent against too lower suction pressure.
I. Mount protection controller for post expansion valve temperature, then shut off compressor when the post calve temperature is too lower.
J. Mount low-temperature protection controller for chilled water outlet for with cements of high temp-sensitivity.
K. Pay attention to avoiding the failure or delayed control of controller.
Corrosion prevention
A. In order to prevent corrosion heat exchanger against, if must be guaranteed that no affect of corrosion from the heat exchanger mounted and in-service environment as well as medium for exchanging heat on stainless steel metal and copper metal will take place(the content of chloride ion and sulfate ion in heat exchanging medium usually does not exceed 100mg/l)
B. Use the filter screen with mesh less than 1mm in such way the floccus, filaments and bigger sundries are prevented to entering the heat exchanger resulting in blocking.
C. Clean the scaling inside the heat exchanger in time.
D. Ensure that the system is in constant operation to prevent the plates of heat exchanger against strain corrosion resulted from the violent or frequent changes of pressure of system pipes.
E. The liquid into heat exchanger shall be fully drained when the system shuts down its operation and be in long-term non-service.
Cleaning
As for plate heat exchanger, the scaling will occur when the pressure drop increases during its operation. Clean the general oil scaling with cleaning agent; in case of serious scaling, clean it in reverse flow manner for 24 hours with chemicals nondestructive to stainless steel metal and copper metal)e.g. phosphoric acid with concentration of 5% or peroxide acid, mosquito acid, citrate, acetic acid, oxalic acid or other organic acids). When cleaning, control the flowing velocity of cleaning liquid by means of pump pressurizing and the optimum flowing velocity is 1.5-2 times of that of previous liquid. After completion of cleaning, wash the cleaning liquid in the system with plenty of cleaning water, prior to starting the system.
