ARES Plate Heat Exchanger

Plate heat exchanger (PHE) is a type of heat exchanger that uses metal plates sealed with gaskets to transfer heat between a hot fluid with a cold fluid. It consists of a frame, which consists of a front cover, rear (movable) parts, carrying bar, guiding bar, and a number of tie bolts depending on the type of the plate heat exchanger.

The heat is transferred from one medium to another through plates, which have been pressed. The hot and cold medium flows through between each of the plate and then they exchange their heat without mixing each other. Liquid flowing through the PHE channels experience turbulent flow at low velocities producing high heat transfer efficiency and low fouling which results in smaller and a compact unit. A PHE has wide industrial applications especially in HVAC, oil and gas, power generation, edible oil etc.

Plate Heat Exchanger Structure

Plate Structure

The heat transfer plates are mainly produced from SS304, SS316, SMO, Hastelloy or Titanium material, 0.5 mm – 1 mm plate sheets. In general, there are two types of plate for each model which are thermally long and thermally short plates. The difference between them is that the wide and narrow angle on the herringbone pattern.

Thermally Long Plates:

  • High turbulence output
  • Close temperature approach (LMTD: 1°C)
  • High pressure loss

Thermally Short Plates:

  • Low turbulence output
  • Low heat transfer value
  • Low pressure loss

Gasket Types

Gaskets are among most critical element of the plate heat exchanger. Depending on the temperature and fluid type the material of the gaskets may vary. The most common type of gaskets are NBR and EPDM gaskets. For different applications there are other specific types of gaskets such as Viton and Silicone. The contamination or mixing of the two fluids are prevented by using the following gaskets system. Only one side of the gasket has contact with the fluid and the other side has contact with the atmosphere. Therefore, in any case of leakage the fluid runs outside of the plate heat exchanger rather than mixing with the other fluid.

Gasket TypeMaximum Working Temperature
NBR120 °C – 140 °C
EPDM140 °C – 160 °C
Viton180 °C – 200 °C

PHE Series

AWG Series – Wide Gap Plates

AWG Series consists of only wide gap plates. Compare to A Series plates, AWG plates have 5.5 mm to 12 mm plate gap which makes them easier to use in applications where contamination in the fluid is high.

ASW Series – Semi Welded Plates

A cassette contains two plates laser welded together. The advantage of this method is; one side has a welded plate channel and the other side has a traditional plate channel with gaskets. On the welded side, there are two specially produced corner hole gaskets creating the sealing between two cassettes. Thus, the gasket exposure to the fluid is reduced to a minimum on welded side.

ADP Series – Double Wall Plates

Two plates lair-welded together to ensure safety. For applications such as pharmaceutical industry, food & beverage, district heating, cooling of transformer oil, etc, where it is crucial that medium are not mixed.
