RFQ

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.

COMPONENTS OF PLATE HEAT EXCHANGER

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

FRAME A & FRAME B

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

Plate arrangement

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.
