Double Wall Plate Type Heat Exchanger

Double Wall PHEs are a compact solution to conventionally used double wall shell and tubes and double coils. 
 The double plates offer maximum safety against intermixing of the two fluids in the plate type heat exchanger. The double plates are constructed by laser welding 2 identical plates around the ports. Thin air gap between the plates ensures that if any one of the two fluids would leak through the first plate it would leak to atmosphere and would be visible outside.Some Applications of Double Wall PHEs are:
 Transformer Oil Cooling
Water contamination in transformer oil can result in severe damage to the transformer and can result in plant shutdowns.

Lube Oil Cooling
Oil mixing with the cooling medium (sea, lake, river or cooling tower water), can cause severe damage to the environment. Also, if the cooling medium mixes with the oil, serious damage can be caused to the equipment being cooled.

Quench Oil Cooling
Water mixing with quench oil can cause a steam explosion.

Chemical Processes
Intermixing of process media can create accelerated corrosion, an explosion, undesirable chemical reactions or contamination. Example:  Accelerated corrosion results in chlorated hydrocarbons intermix with water to produce hydrochloric acid.

Food and Pharma Processes
Product intermixing with the other media may contaminate final product.

Semi-Welded Plate Type Heat Exchangers
In the past no satisfying solution was available for using gasketed plate heat exchangers for special process conditions or aggressive media. The limitation was always the gasket material.

Semi-welded units overcome this limitation! These are as flexible as gasketed heat exchangers while enhancing the application range for PHEs for use with aggressive fluids and gases, such as ammonia or aggressive process chemicals where suitable elastomers are not available to act as a sealant between the plates. In the case of ammonia refrigeration, the reduced hold up volume results in significant additional savings.

This type of heat exchanger uses a unique approach. Alternating channels are laser welded. Aggressive media (for example Ammonia) flows in the welded channels. Non-aggressive media (like brine or water) passes through gasketed channels. Despite partial welded construction, the unit can easily be disassembled to replace gaskets or to take care of other maintenance.

Like all VARALKA products, they are also highly efficient, reliable, and easy to operate and maintain.

Applications of Semi-Welded PHEs
  • Ammonia Evaporators - DX or Flooded
  • Ammonia Condensers
  • Ammonia De-superheaters, Economisers
  • Oil Coolers
  • Sulphuric Acid Coolers

TypePlate, Heat Recovery

Welded Heat Exchangers
Productivity improvements is an ongoing agenda for industries world-wide. Heat Recovery and Solvents Recovery can be useful tool in this objective. Equipments to recover waste heat or solvents help in sustainable development as well as increased efficiency of processes.

Varalka welded heat exchangers offer a solution! Gas Gas Heat Exchangers can be used for Exhaust Gas Heat Recovery, Waste Heat Recovery Heat Exchangers and Solvent Recovery. These are all metal construction with plates welded to each other by laser welding. These heat exchangers can be used to transfer heat from Gas to Gasor fromGas to Liquid.
