Two plates are laser welded with each other and are called as a twin plate or cassette. These two cassettes when joined, from channel where other fluid flows.

These units are mostly used as evaporators or condensers, where the gaseous fluid Flows within the cassette and the other fluid flows through the gap formed by cassette.

These units are also used in application where primary fluid is not compatible with the regular gaskets.

The gasket material used is Nitrile rubber, EPDM, VITON and NEOPRENE as ring gasket.

The plate material used, based on process parameters and the fluid are diversified like, SS316, Titanium, and SMO 254 etc.

The PHE size in this range varies from 2 connection size to a maximum of 10 connection size.

Manufacturing is done by rolling two sheets around a centre core to form two concentric spiral passage. The sides are welded and forms two passage . one for hot and another for cold fluid.

• The plate gap is maintained by welded studs and this can be tailor made as per the requirement of the applications.
• Circular design
• Large surface to volume ratio and hence very compact
• Easy maintenance
• Counter current flow

As this single passage and this induce high shear stress and hence any particle in the passage that will be scrub away as they form. Hence reduces fouling, .

• For high viscosity fluid
• Fouling Liquids, Fibresm Sludges etc
• As solvent recoverycondenser in Pharma Industru

Coil type Prime surface heat exchangers finds various applications due to its versatile design. This can be tailor made to the needs of customer and their applications.

• Immersion heating and cooling
• Clamp-on vessels and storage tanks
• Heat recovery etc

The contact point inside plate gap is almost negligible.

• The plates contour move in parallel with each other and do not meet.
• This unit is unit in fluids, where either Viscosity is very high or % solid and fibrous material is very high. Free flow nature of plate help in passing of fibrous and highly viscous material without hindrance.
• The plates finish confirms to 3A standards.
• Plate gap range from 5 mm to 12 mm all throughout - Free flow.
• The gasket material used are Nitrile rubber, EPDM
• The plate material used, SS316 etc.
• The PHE size in this range varies from 4 connection size to a maximum of 14 connection

plate heat exchanger consists of corrugated plates fixed with gasket and these are mounted between fixed frame and movable frame , top and bottom carrying bar are used for hanging the plates in between frames and the ties rods are used for tightening to the required plate pack. fluids enter through the connections in the frame and are distributed in between plates. the fluids flow thorough alternate passages between plates by means of gasket arrangement.

• more than 50 sizes available with every size two to three plate pattern
