PHE3

The PHE was invented by Dr Richard Seligman in 1923 and revolutionized methods of indirect Heating and Cooling of fluids. The PHE is probably the most efficient liquid to liquid heat exchanger available today.

 

The PHE consists of a series of thin, corrugated alloy plates which are gasketed together in a carbon steel frame to create an arrangement of parallel flow channels. Ports at each corner of the plates act as the headers and the gaskets direct the fluid flow as well as provide the primary seal for the system. One fluid in the odd numbered channels and the second in the even.

 

It has a major advantage over a conventional Heat Exchanger in that the liquids spread out over the Plate. This facilitates the transfer of Heat, and greatly increases the speed of the temperature change. It is not as common to see PHEs due to the fact that they need well-scales gaskets to prevent the liquids from escaping, although modern manufacturing processes have made them feasible.

 

In a PHE plates are generally arranged in such a way that it forms channels of hot and cold liquid alternately. Due to corrugations in the plate, high turbulent flow increases the heat transfer rate. 

 

As compared to Shell & Tube Heat Exchanger, PHE can give approach of 1°C whereas Shell & Tube Heat Exchanger gives approach up to 5°C.  For the same amount of Heat Exchange the size of the PHE is less, because of the large Heat Transfer area afforded by the plates (the large area through which heat can travel).

Expansion of the Heat transfer area is possible in PHE. Due to the above reasons PHE are used for the better and controlled Heat transfer.

 

Some of the big players in the PHE business are :

Alfa Laval - APV - GEA - Vicarb -  Sondex - Pasilac - Schmidt Bretten - Tranter / Swep

 

 

The main advantages of PHE are:

 

• High Heat Transfer Coefficient with low surface areas
• Compact design, does not need much space
• Small temperature differences are possible between the fluids
• High versatility, the design allows for fast and easy rearranging of the plates as operating
   or process conditions change
• Movable pressure plates allow easy access to the plates for cleaning
• Low investment costs
• High corrosion resistance
• A plate exchanger contains only low quantities of fluids
• Easy to service

PHE



Reconditioning of PHE demands a high level of experience and expertise

 

Our principals are equipped and staffed by experts to provide you with unrivalled of service.

Their teams work to a carefully planned and rigorously enforced regime to maximize quality and customer satisfaction at every stage:

• Gaskets are removed in a liquid bath
• Plates are degreased,de-scaled and passivated in heated baths
• 100% dye penetrated check
• Plates are high –pressured washed using an automated system
• Every plate is individually inspected and passed prior to shipment

 

 

3. POLLUX Business can supply you with:

• Complete fully refurbished and/or New Units of PHE (Titanium Plates in a very wide range)

 

  Our Servicing Package consists of the following steps :

   

   Frame Handling

  Cleaning

  Dye Penetrant Testing  

  Regasketing
