What is gasket in plate heat exchanger?

In a gasketed plate heat exchanger, the plates are fitted with elastomeric gaskets which seal the channels and direct the fluids into alternate channels. The plate pack is assembled between a frame plate and a pressure plate, and compressed by tightening bolts fitted between these plates.

What is plate evaporator?

Plate Evaporator is a type of evaporator in which a thin film of liquid is passed and flows between the plates for the process of evaporation. The Plate Evaporators are also known as the gasketed plate and frame evaporators.

What are the parts of plate heat exchanger?

A PHE consists of a pack of thin rectangular plates with portholes, through which two fluid streams flow, where heat transfer takes place. Other components are a frame plate (fixed plate), a pressure plate (movable plate), upper and lower bars and screws for compressing the pack of plates (Figure 2).

Where is plate type heat exchanger used?

The plate heat exchanger (PHE) is a specialized design well suited to transferring heat between medium- and low-pressure fluids. Welded, semi-welded and brazed heat exchangers are used for heat exchange between high-pressure fluids or where a more compact product is required.

What are the advantages of plate heat exchanger?

Advantages of Plate Heat Exchangers; A lower cost option wherever stainless steel is required. Higher operating pressure capabilities. Higher temperature capabilities. Ideal for small district heating, beverage cooling, food and pharmaceutical production and low duty oil cooling applications.

Where are plate heat exchangers used?

Some of the applications where this high efficiency is evident when using the Graham Brazed or Gasketed Plate Heat Exchangers are:

• Water heaters.
• Cooling tower isolation.
• Free cooling.
• Waste heat recovery.
• Heat pump isolation.
• Thermal (ice) storage systems.
