Plate Heat Exchanger
Plate Heat Exchanger
CONSTRUCTION OF A TYPICAL PLATE HEAT EXCHANGER
Plate heat exchanger is a most versatile heat transfer device and a preferred choice for a wide variety of applications. The heat exchangers are constructed on a modular concept and in a wide variety of plate and sealing materials. As a result of this concept and by using a mix-n-match technique, plate heat exchangers can be easily adapted to meet different requirements of the heat transfer, satisfactorily. The heat exchangers can be easily inspected and cleaned ensuring specified heat transfer for the lifetime of Heat Exchanger.

Gasketed Plate Heat Exchangers
Most common and versatile heat exchanger! Available in variety plate & sealing materials. Ideal choice for:
- Hydraulic and Lube Oil Cooling
- Closed Cooling Water Circuits
- Heat Recovery Applications
- HVAC Applications
- Various Applications in Chemical Industry
Brazed Plate Heat Exchangers
Brazed PHE is constructed as a plate assembly of corrugated plates and vacuum brazed. Brazing joint is formed at all contact points between the plate and filler material — copper. Commonly used
for following applications:
- Oil Coolers
- Evaporators and condensers for Chillers
- Air dryers
- Cascade Systems
Semi Welded Plate Heat Exchangers
Semi welded PHEs are an optimum solution in applications where gaskets are not compatible with one of the media.
Our semi-welded PHEs are assembled with thermowave laser welded modules. These are useful for applications such as:
- Ammonia condensers and evaporators
- Sulphuric Acid cooling
- Vapour Condensors
Spares & Service
All plate heat exchangers require maintenance at some point. Gaskets are replaced periodically and for some special applications plates may also need to be replaced.
VARALKA provides trained service engineers to assess the heat exchangers to restore them to its optimum functionality. We also stock replacement plates and gaskets for all leading plate heat exchangers manufacturers — Alfa Laval, Tranter, APV , GEA, Sondex.
