Welded Plate Heat Exchangers

VARALKA Welded Plate Heat Exchangers are light and compact and offer efficient heat transfer for a wide range of clean and dirty process duties. Hence these are now becoming first choice of process engineers for heating, cooling, condensation and evaporation of water, steam, gases vapours, and hydrocarbons, amines, glycols etc.

Varalka welded heat exchangers are made with thin and efficient heat transfer plates in different sizes, shapes, thickness, and corrugations. Baffles can be installed to enable a multi-pass design or modular design for high flow rates. As there is no gasket, there are no restrictions due to gasket materials.

These heat exchangers support high temperatures (upto 1000 ˚C) and large flow rates. Modules can be removed for easy mechanical cleaning. Small hold up volumes allow quick response time, fast cleaning, and hence high productivity.

Shell and Plate Heat Exchanger

Varalka Shell and Plate Heat Exchanger is a solution for a demanding working environment requiring high efficiency in a compact size. These welded heat exchangers combine the merits of shell and tube heat exchanger with advantages of conventional  plate heat exchangers, The Plate and Shell Heat Exchanger consists of corrugated circular metal plates that are welded together and installed into a pressure vessel to provide high heat transfer.
