Plate Heat Exchangers
Efficient Heat Transfer For Every Industry
The Tranter gasketed plate heat exchanger is designed to provide maximum efficiency in transferring heat from one liquid to another or from steam to liquid. It consists of a series of gasketed, embossed metal plates arranged alternately and bolted together between end frames to form channels through which hot and cold media flow. The hot fluid flows on one side of the plate while the cold fluid flows on the other, with the plate itself providing the most effective means to transfer heat from one fluid to the other. Gaskets on the plates seal the channels and provide flow direction.
As liquids flow counter-currently through the channels between the plates, the cold liquid becomes warmer and the hot liquid cooler. Most units are designed for a one-pass/one-pass flow arrangement, resulting in all nozzles being installed on the stationary end frame, which facilitates simpler piping arrangements and easier disassembly.
Due to its high efficiency, the plate heat exchanger unit can handle temperature approaches of less than 1°C. It also offers “U” values in excess of 1,500 Btu/hr ft2 °F, which is significantly greater than other exchangers, due to the unique turbulence created by its corrugated plates, which eliminates stagnant areas in liquid flow and promotes maximum heat transfer. This translates to a less expensive and more compact heat exchanger.
The unit’s velocity profile and induced turbulence causes dirty product deposits to be continually removed from the heat transfer surface during operation, thereby reducing fouling. Effective use of the plate’s turbulence can be made with in-place cleaning, which allows backflushing water or pumping cleaning solutions into the unit without disassembling. Units can also be taken apart for cleaning the plate surfaces. Plates can be electropolished to make cleaning easier, either manually or in-place.
