Construction Principle of Design :

The Graphite Impregnated Block is Permanently 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 Not The Header According To The Corrosive Nature of The Fluids. A Variety of Multi-Pass Arrangements Can Be Accommodated 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 Particularly Useful 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 Exchanger 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.
