Applications

The Graphite heat exchangers are suitable for applications that require andling of corrosive liquids and gases

Typical applications include:

Main features

Great versatality

HIGH RELIABILITY

Unequalled heat transfer performance

CONSTRUCTION The graphite impregnated block is permenantly compressed between cast iron clamping plates,with tie bolts passing through the lugs at the corners.There are series of parallel holes between opposing faces for the passage of process and service fluids.The headers are made of cast iron.Other coatings can be done ont the header according to the corrosive nature of the fluids. A variety of multi-pass arrangements can be accomodated by incorporating partitions inside of the headers.

Split or graduated multipass arrangements can also be supplied.By using multi-pass headers,velocity of the process and service fluids can be adjusted to the most economic figure. This gives a close approximation to close counter current flow,which is paricularly useful for for heating or cooling fluids or heat recovery duties.With the cross flow principle and using graphite headers on both sides of the block,the heat exhanger can handle corrosive fluid.     Gaskets are only used between the graphite block and the removable headers; any leakage is to atmosphere where it is immediately detectable.Contamination of the process fluid by the service fluid is impossible.

Features:

• Heating corrosive fluids with steam gases or hot fluids.
• Cooling corrosive fluids with other cold water, brine or other fluids
• Condensing vapours or gases
  • Proprietary impregnations
  • Multiple header arrangements
  • Interchangeable headers
  • Rugged Construction
  • Highly resistant to thermal shock
  • Takes overloads since all graphite is kept under compression
  • No cemented parts
  • Only fine grain graphite is used

  through effective baffle arrangement.

  • Optimum velocity can be obtained all along heat exchange path

  Compact construction

  • Large surface area in small volume
• Process and service fluid holes drilled in a solid block of Graphite

  Models from 0.7 M² to 50 M²

  Applications:

  Liquid/Liquid heat transfer.Suitable for cooling and heating of gases and condensing of vapours where heat transfer coefficient on one side is low.

  Design Conditions:

  Maximum design pressure:6 bar gauge(75 PSIG)

  Test Pressure: 12 bar gauge(112.5 PSIG)

  Design temperature: varies according to the type of graphite used in the construction of the block(maximum 400C with graphite).
