Plate Heat Exchanger Applications

Petroleum refining and petrochemical processes are going through drastic changes with inflation of petroleum price and global warming. Consequently, functional advancement of chemistry products have been modified to be on par with society, industries and environmental progress.
As such, focuses have been set in producing facilities and machineries that can:

- Energy and cost effectiveness
- Reduce carbon footprint
- Process precision and flexibility

HISAKA PHEs are ideal because:

(a). It is extremely safe to be used and manipulate
(b). Reduced carbon footprint
(c). Excellent heat performance
(d). Minimal thermal energy consumption

(e). Simple and quick machinery assembly
(f). Ease of modifying heat performances (by increasing or reducing the number of plates)
(g).  Reduced installation space



Papers are essential item in modern society. It was once predicted that paper will be eventually replaced with the evaluation of information technology, internet and television; yet, truth has indicated otherwise.
In pulp and paper industry, energy conservation is vital to ensure that papers can be produced with the least energy consumption and at the lowest possible cost to warrant the highest profit margin possible. Furthermore, with increasing environmental awareness from the local authorities, manufacturers are looking for high performing energy conservation systems that does not only provide competitive advantages, but also reduces on environmental stress.
Extensive research and developments have been conducted to ensure that all HISAKA Plate Heat Exchangers (PHEs):

1. Have high heat transfer efficiencies yet at a lower energy consumptions
2. Usable in biomass energy reproduction by recycling the energy produced from the pulps and paper productions

HISAKA's sincerities extended from providing the full range productions of high performance PHEs, to excellent after sales services and maintenance. As HISAKA's motto "Magokoro" explains - innovative technologies are sincerely delivered.



Parts of Plate Heat Exchanger

The heat transfer plates are thin sheets of corrosion resistant metals such as stainless steel or titanium and etc. that are press-formed with a corrugated pattern on their surfaces, and sealed with synthetic rubber gaskets in their groove, which seal the flow channel and direct the fluid into alternate channels.

Such plates are suspended, supported and aligned by guide bars, and tightened by bolts and nuts between fixed and movable frame.

The equipped can adjust the number of plates so as to meet the heat duty.



Heat Transfer Plates

Each heat transfer plate is corrugated to various patterns to increase its strength and heat transfer area. Furthermore, the corrugation creates high turbulence and thereby achieve high heat transfer coefficient. The plate is provided with passage hole on each corner. Each plate is tight-sealed with a gasket fitted in its peripheral groove.


Flow Channel

The plates are divided into A-plate and B-plate, and a passage is formed between these plates. The high temperature fluid flows alternately and in the opposite direction of the other fluid. Thus high efficient transfer of heat is achieved through these plates. A-plate when reversed would become B-plate. As such only one type of plate cab be used as A-plate and B-plate for most models.


Pass Design

With single- pass design, all of the connections are made on the fixed frame side only. This simplifies piping work and increases layout flexibility. With a multi-pass design, connections are located on both the S-frame (fixed-frame) and E-frame (movable-frame) sides making it necessary to remove and adjust the piping.
