COMPONENT
Plate Heat Exchanger consists of the plate pack pressed together in a frame and sealed at their edges by a compressible gasket to from a series of interconnected narrow passages which fluids are pumped. The hot and cold fluids flow in alternate passages, and heat is transferred through the thin plates with relatively low thermal resistance.

 The main components of HEXA Plate Heat Exchanger:

FRAME
The frame enclosing the plate pack is held together with tightening bolts. It consists of a fixed frame, a loosed frame, a supporting column and guide bar.

Type of Frame:
         Frame A : Takes plate pack lengths up to 250 mm.
                            Number of Plates < 51 Plates
         Frame B : Suitable for long plate pack lengths
                            Number of Plates > 51 Plates

Material of Frame
         Stainless Steel
         Carbon Steel

 
COMPONENTS OF PLATE HEAT EXCHANGER
   
CONNECTIONS
connections for incoming and outgoing media are usually in the fixed frame of the plate heat exchanger. In the case of multi-pass flow, connections have to in the fixed frame and the loosed frame.
Type of Connections:
         UNION
         NIPPLE
         FLANGE
         Etc.

PLATE PACK
         The plate pack consists of series of plates, separated by gaskets. Alternate pairs are connected via ports forming two separate flow channels. Heat transfer between forming media streams, often in counter flow, occurs through the plates as a result of temperature difference between the liquids on the plate surface.
Type of Plate:
     1. The "W" plate
             higher degree of turbulence
             close temperature approaches
             higher pressure drops
     2. The "F" plate
              lower degree of turbulence
              larger temperature approaches
             lower pressure drops
     3. The "W&F" plate
           A combination of "W" and "F" plates is capable of generating a large number a            characteristic heat exchanger duties.
Material of plate
              Stainless steel AISI 316
              Stainless steel AISI 304

GASKET
         Gaskets on the plates ensure that the flow channels are securely sealed from each other. The gaskets also determine the direction of flow within the plate heat exchanger.
Type of Gasket:
              EPDM can withstand steam, hot water and weak acids.
              NBR performs very well in oils, glycols, hydrocarbons and alcohols.
              Viton is highly resistant to oxidizing acids, hydrocarbons and various             solvents.
