Key Components of a Plate Heat Exchanger
- Plates: The core element. Typically made of stainless steel, titanium, or other alloys resistant to corrosion and high temperatures. The pattern and number of plates determine the heat transfer capacity.
- Gaskets: Seals the plates and defines the flow channels. They are usually made from synthetic polymers (like NBR, EPDM, Viton) chosen for their compatibility with the fluids and operating temperatures.
- Frame Plate (Head): The fixed end of the frame that holds the stack together.
- Pressure Plate (Follow Plate): The movable end of the frame. When tightened, it compresses the plate pack.
- Carrying Bar & Guide Bar: Support the plates and ensure they are aligned correctly during assembly.
- Tightening Bolts: Large bolts that compress the entire plate pack between the frame and pressure plates.
