Less space required
It requires less space but supplies more area of heat exchange. No extra space being required for maintenance. The plate heat exchanger (PHE) only asks for 30% of a space and one-fifth to one-tenth of an area of those of the tubular heat exchanger (THE).?
Light weight
Owing to its small frame and overall size, the weight is reduced by 50%.
High heat transfer coefficient
Owing to high turbulent flow of fluids in PHE, heat transfer coefficient of PHE is 3-5 times more than that of THE.
Easy assembling, dismantling and maintenance. It is easy to increase or decrease heat transfer area.
Because of non-welding structure of PHE, it is easy to dismantle, clean, replace, increase or decrease the number of plates. This offers more flexibility.
Lower scale sludge.
Smooth plate surface and high turbulent flow cause less scale sludge. Its heat resistance coefficient is only 1/5 of THE.
Prevent mixture of two media fluids
When media fluids leak out from the sealed gasket, only one way is passable from the drain channels to the outside. This keeps fluids from mixing.
High heat recovery efficiency
Counter-current flow for high heat transfer efficiency reduces the temperature difference between end ports which can be up to 1℃. Heat recovery efficiency can reach 95%.
Less remained fluids
It is 80% less than that of THE.
Economic investment
Under the condition of same materials, investment in the PHE is 50% lower than that in THE.
