Plate Heat Exchangers

Precision Plate Heat Exchangers are proven to be reliable and highly efficient in heat exchange process. PHE are considered as a best solution for the heat exchange process. PHE can be used even in low temperature difference between the media. PHE are available in different sizes, material grades different plate configuration, different gasket material which makes the PHE suitable for various application. Its easy dismantle construction allows to add more plates in case if we want to increase the duty of PHE.

Construction

Pleat heat exchangers consists of series plate with gasket compressed together in a carbon steel frame. Plates are hanged on the carry bar and kept in line by a guiding bar. length of the carry bar, guiding bar and tightening bolts will change in different models.
