HISAKA PHEs are Specially Made to be Well Suited for the Oil Palm Industry, Especially for Refinery and Hydrogenation Processes.

• The Mechanism of efficient heat transfer 

• Hot Fluid (e.g RBD) and cold fluid (e.g CPO) are flowed through the four specified portholes at the four corners of each heat transfer plate. These heat transfer plates are made of press-formed thin sheets of metal with a high corrosion resistance (e.g. stainless steel or titanium). One plate can be used in two ways: either as an A-plate or by, turning it upside down, as a B-plate. Plate channels are formed between these heat transfer plates. The hot fluid flows in the opposite direction to that of the cold fluid, and heat transfer is performed.

• A heat transfer plate has various corrugations and grooves for mechanical strength and its increased heat transfer area. The plate, with corrugations and spherical bumps on the surface, is designed to induce turbulence of the fluids in the plate channels, and therefore to achieve a very high heat transfer coeficient and the most efficient heat transfer. A gasket mounted in the peripheral groove of the plate to seal the fluid in.      

• Features

Prevention of liquid inter-mixing 

Special consideration is taken into the gasket so as to protect  it from direct attack by liquid. Furthermore, the gasket is of double-seal type so as to permit liquid draining outside the exchanger even in a case of liquid leak caused by its deterioration.

Easy change of performance 

According to change of the treating capacity, the heat transfer surface area can be incremented/de-cremented by unscrewing the plate clamping bolts and increasing or reducing the number of plates.

Steam available  as heat source 

The use of synthetic rubber gasket  of special composition permits to use steam as heat source, i.e. operating temperature range up to 180ºC maximum.

Less installation space

The lightweight and compact construction reduces the installation space and the weight to 1/4 and 1/3 of shell & tube heat exchanger respectively. In addition, lightweight and thin heating plate with less liquidhold facilitates the installation work. The Plate Heat Exchanger can be disassembled for cleaning without piping work, while the shell & tube heat needs a additional space for drawing out the tube bundle. 

High performance 

The overall heat transfer co-efficient (U-value) ranges from 4,000 to 9,000 W(m2·°C) in water application, since the plate corrugation provides high turbulent flow. This is one of the reasons why plate heat exchanger is so high heat transfer coefficient. In addition, this turbulent flow also acts to prevent scales from the plate surface.

Two fluids temperature difference up to its extremely close

The construction which permits heat exchanging in perfect counter-current flow with very high heat transfer efficiency makes it possible to utilize the temperature difference between hot fluid and cold fluid up to 1ºC and less.
