Gelan produced plate heat exchanger, heat transfer efficiency significantly improved, high pressure, corrosion resistance, compact structure, small size, stable operation, disassembly 69 times without leakage, long service life, applicable to a wider range of working conditions, more stable operation.
Plate heat exchanger is one of the most basic heat transfer devices whose design allows for good conduction of thermal energy between two fluids to take place efficiently. The apparatus is presented in the form of several thin plates that take the shape of channels by being placed one above the other where fluids flow across to exchange heat.
Working Principle:
1. Fluid Heat Transfer: One fluid enters the plate heat exchanger through the inlet, flows along one channel of a stack of plates. The other fluid flows along the sides of, or over top of these plates. Compressed by the other fluid, in the opposite direction, this setup allows for the transfer of heat from hot fluid to cold fluid without mixing the two liquids together.
2. Increased Heat Transfer Area: The plates are corrugated in design, which enhances the surface area for heat transfer. This increases the strength of the force convection done by the fluid and also adds to the effectiveness of the plate heat exchanger regarding heat transfer efficiency.
3. Heat Conduction: The plates are closely packed to maximize the transfer of heat between the fluids. This arrangement also enables convective heat transfer. Therefore, the overall heat transfer efficiency would be improved in the plate heat exchanger.
4. Reversible Operation: The plate heat exchangers are reversible, and thereby, allow the two fluids to transfer heat without mixing. This process of reversibility will enhance the efficiency and allow a heat transfer process that is efficient.
These seal the plates using gaskets with great efficiency and are easily breakable in case their maintenance or cleaning is required. They are highly efficient and thus commonly used in heating, ventilation, air conditioning, refrigeration, and food processing.
Brazed PHEs are permanently sealed and are smaller and more compact in size compared to gasketed exchangers. In applications where high pressure and temperatures are found, Brazed PHEs are applicable. These can be best applied in hydraulic systems or refrigeration circuits.
Welded plate heat exchangers are perfectly applicable when the conditions are high pressure and temperature. Gaskets are replaced by welding the plates together, so it is leakage-proof for different applications like petrochemical processing.
● ISO and ASME Compliance: Manufactured based on ISO and ASME standards so that the CE and FDA are highly obtained in order to achieve excellent quality of manufacture up to 80% without having a high failure rate, hence little or no maintenance cost.
● Precision Engineering: Gelan has 415 international-grade plate and gasket molds and 31 CNC precision machines which are able to produce high quantities in both standard and custom applications. The gaskets are very tough, withstanding up to 69 disassemblies without leakage, far above the national requirements.
● High Heat Transfer Coefficient: The scientifically designed corrugated plate structure leads to turbulence at low fluid velocities. Risk of scal-ing is at a minimum and a heat transfer coefficient of 3500 to 7000 W/m²·°C can be achieved.
● Low Pressure Loss: Optimised corner hole design and streamlined flow paths provide low pressure drop. Pressure loss is reduced and, therefore, the overall system efficiency is increased in the plate heat exchanger.
● High Pressure Resistance: Reinforced plate gaskets and the precision-molded corrugated surfaces ensure that the Gelan plate heat exchangers could bear pressures of up to 2.5 MPa.
● Extended Service Life: The gaskets are of quality and from world-renowned manufacturers that prevent corrosion, and their non-stick pad structure guarantees uniform tensile strength for long durability in a Gelan plate heat exchanger.
● Reliable and Leak-Free Operation: For reliable and leak-free operation Gelan’s two-channel sealing structure carries minimal deformation and has a high resilience, which means that the aging of gasket is slow. The two-channel sealing structure of Gelan assures reliable sealing and seals off any leakage in a plate heat exchanger.
Please note that the final cost depends on the customized service you require, the specifications of the raw materials used, the relevant national laws, and the distance of transportation. Take the example of booking a tall container of products:

Plate heat exchanger is widely used in bath, medicine, food, husbandry, paper, textile, mining, petroleum, metallurgical heat and other industries, can be used for heating, cooling condensation, bacterial disinfection, waste heat recovery and other large, small and medium-sized a variety of working conditions.
A plate heat exchanger is a heat exchange device in which heat is transferred from one fluid to the other without their mixing. Constructed from stacks of a number of thin plates, narrow channels are formed for passing fluids through them; with these, moving fluids create a direct transfer of heat between the hot fluid and the cooler fluid. This way, it ensures effective heat exchange in minimal space and material.
A plate heat exchanger differs from a shell-and-tube heat exchanger due to its lower weight, easier construction and cleaning, easier maintenance, and efficiency in heat transfer more than shell-and-tube heat exchangers.
Due to the superior quality of Gelan’s gaskets as well as the rigid construction, maintenance intervals are stretched to such an extent that gaskets in GEA plate heat exchangers resist up to 69 disassemblies without leakage.
Yes, a plate heat exchanger may operate at temperatures up to 250°C, although it is again dependent on the particular gasket material used.
Gelan reinforces gaskets, and precise processing of molds with the use of high-grade materials enables plate heat exchangers to have long service life and corrosion and pressure stress resistance.
