ARES PLATE HEAT EXCHANGER

Plate Heat Exchanger Introduction

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. Liquid flowing through the PHE channels experiences 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.

WORKING PRINCIPLE OF A PLATE HEAT EXCHANGER

A plate heat exchanger 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. In between front and rear frame, a number of plates are pressed together. When the plate pack is placed between two frames, it is tightened to minimum distance which results for the plate heat exchanger to worked under certain pressures.

 

The heat is transferred from one medium to another one 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.

STRUCTURE OF PHE PLATE

The one of the most important parts of the plate heat exchangers is the plate itself. The plates are pressed from various materials such as stainless steel to pure titanium with special design which creates turbulence to achieve highest heat transfer rates. The material of the plates depends on the medium passing through the plate heat exchanger. It is very important that the medium must be suitable for plate material otherwise, aggressive medium can damage the plates.

 

The plate thickness depends on the application and working pressure, which is usually between 0.4mm and 1mm. Thickness of the plate differs depending on the type of ARES Plate Heat Exchanger as well.

PHE GASKETS DESIGN

Each plate is equipped with a gasket which prevents the medium mixing with each other. Gasket material varies depending on the application, NBR and EPDM is the most commonly used throughout the world for plate heat exchangers. Some other material such as FKM, Silicone or other special material may be used.

 

ARES Plate Heat Exchanger uses hang on gasket type where glue is not used at all. The glueless application makes it very easy for service and re-gasketting of our plate heat exchangers.
