External Structure The heat transfer plates are thin sheets of corrosion resistant metal such as stainless steel or titanium that are press-formed with a corrugated pattern on the surface and sealed with synthetic rubber gaskets, which seals the flow channel and directs the fluid into alternate channels. Such plates are suspended, supported and aligned by guide bars and tightened by bolts between a fixed and a movable frame. The equipment can adjust the number of plates so as to meet the heat duty.

Flow of Fluid and Heat Exchange Mechanism Heat transfer A and B-plates are of identical pattern. One simply turned upside-down becomes to the other so as to obtain a dif-ferent flow channel by the gasket line. Further, by the start plate (D-plate) having its portholes with double seal gaskets and the blind last plate (E-plate), the construction is such that the fluids do not directly contact the frames.

Heat Transfer Plates

FEATURES

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.

The plates are divided into A-plate and B-plate, and a pas-sage 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 can be used as A-plate and B-plate for most models.

Flow Channel

With single-pass design, all of the connections are made on the fixed frame side only. This simplifies piping work and in-creases layout flexibility. With a multi-pass design, connec-

tions are located on both the S-Frame (fixed-frame) and E-Frame (movable-frame) sides making it necessary to remove and adjust the piping.

Pass Design

Prevention of Liquid Inter-mixingSpecial 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 deteri-oration.

Easy MaintenanceThe plate heat exchanger can be easily opened for inspec-tion and maintenance by loosening the tightening bolts and nuts. Assembly and opening of the unit are also easily per-formed.

Steam Available as Heat SourceThe use of synthetic rubber gasket of special composition permits to use steam as heat source, i.e operating tempera-ture range up to 180C maximum.

Less Installation SpaceThe lightweight and compact construction saves the installa-tion space to 1/4 and the weight to 1/3 of shell & tube heat exchanger respectively. In addition, lightweight and thin heat-ing 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 addi-tional space for drawing out the tube bundle.

Two fluids temperaturedifference 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 approach the temperature difference be-tween hot and cold fluids up to 1C and less.

Wide Application RangeCapability range : 0.1m3/h to 5,000m3/hOperating pressure : 4.0MPaG max.Operating temperature : 180C max.Surface area : 0.18m2/unit to 2,500m2/unitPlate materials : Stainless steel, Titanium,

High Nickel alloy, NickelOther materials : Conforming to the Japanese and in

ternational standards as applicable.Gasket materials : NBR, EPDM, IIR, FPM, Silicone,

TCG, etc.

High PerformanceThe overall heat transfer co-efficient (U-value) ranges from 4,000 to 9,000 W/m2C in water application, since the plate corrugation provides high turbulent flow. This is one of the reasons why plate heat exchanger performs so high heat transfer coefficient. In addition, this turbulent flow also acts to prevent scales from the plate surface.

PLATE GASKET

The plates are specially selected from various patterns so as to achieve optimum area and cost effective heat exchanger for each-unit. These plates can be classified into three patterns, namely.1. Herringbone pattern such as LX-, UX-, RX-, WX-, and SX-series2. Wash board pattern such as EX-series3. Special wave pattern such as GX-, and YX-series

1. Herringbone patternThe herringbone design in LX-series has corrugations with pitch which is rough and deep. In SX-series, the pitch is fine and shallow, hence LX-series are used in application where low NTU is required, and SX-series are best suited for high NTU applica-tion. UX/RX-series is in between LX-series and SX-series.

Even in the same series, the heat transfer characteristic is different due to plate pattern angle. H plate is suited to high NTU, while L plate to low NTU. When the plates corrugated in H plate and L plate can be mixed together in a unit, intermediate ther-mal characteristics can be achieved.

NTU of 1.5 and less is generally referred to as low NTU, and 3.0 and above is considered as high NTU

SX-seriesUX / RX-seriesLX-series

2. Wash board patternAs this type of plate gas less metal contact, it is normally ap-plied to fluids containing fibers, particles or sludge. We have EX-series.

3. Special patternYX plate is used exclusively for vapor condensation. (See Page 14)GX plate is developed for heat transfer of fluids containing much slurry or high viscosity liquids. (See Page 15)

H plate L plate Mixed arrangement

1. Versatile gasketHISAKA Plate Heat Exchanger is used in almost all process in-dustries, as such the gaskets are specifically selected based on the operating condition. A wide range of gaskets are avail-able such as NBR, EPDM, IIR, FPM, Silicon, etc.Special Hisaka (S-1) glue shall be applied for bonding

2. Glue-free gasket slit-in typeThese plate gaskets do not need adhesive. The slit-in gasket is especially recommended for those applications where fre-quent replacement of the gasket is required. Further, without the adhesives, adhesive odor is reduced. This slit-in type gasket is suitable for such as water treatment Food applica-tion.

3. PTFE Cushion Gasket (TCG)Through our own development, HISAKA has pioneered PTFE Cushion Gaskets for the Plate Heat Exchanger. It is normally used in applications where conventional synthetic rubber would have limitations due to the corrosiveness of the fluid being handled. With this new development, the Plate Heat Exchangers can be applied in much wider field than before due to the chemical resistance and the durability of PTFE.Special double adhesive tape shall be applied for bonding

Features1. Excellent chemical resistance against most chemical especially

organic solvent.2. Due to the elastic core of the TCG gasket, it does not require

strong tightening torque during the assembly of the unit. Thus re-ducing the risks of plate deformation due to over tightening.

3. TCG gasket can be used for one side only, if the non-corrosive fluid is running in the other side where conventional gasket can be used.

SEMI WELDED PLATE CONDENSING PLATE

FEATURES

High heat transfer coefficient owing to uniform distribution of flow to entire heat transfer is by special plate pattern. A couple of plates are laser welded with o-ring at port holes between the plates, thus semi-welded plate heat exchanger can be used for higher pressure compare to conventional Plate Heat Exchanger.

ADVANTAGES

1. High pressure resistance is about 2 to 3 times higher than all gasket type heat exchanger.

2. Save maintenance cost.3. Chemical resistance TCG o-ring and synthetic rubber are se-

lectively used.4. Nozzle pitch dimensions of semi-welded plate heat exchan-

ger are same to those of following plate heat exchangers.WX-10 and RX-10WX-50 and RX-50WX-90 and UX-90Therefore, RX-10, RX-50, UX-90 can be replaced to WX ser-ies without changing location of connection pipes.

5. Different from full welded plate heat exchanger, Semi-wel-ded plate heat exchanger can be easily added plates to in-crease capacity.

6. Semi-welded plates heat exchanger can be disassembled and done easy maintenance against full welded plate heat exchanger.

FEATURES

YX type heat exchanger is specially designed for condenser to provide high condensing performance in characteristic formed various material plates.This characteristic YX shape is enable to be light and com-pact construction and it has the heat transfer performance of 2 to 3 times as high as conventional S&T heat exchanger.

ADVANTAGES

1. Heat Transfer coefficient is about 2 times as high as that of shell & tube heat exchager. The condensing surface is al-ways secured and the heat transfer coefficient is improved because condensate is immediately drained out.

2. To achieve much less vapor pressure drop than the conven-tional Plate type Heat Exchanger, special consideration of plate characteristic is taken in contribution.

3. Cooling water consumption is about half of S&T heat exchan-ger.

4. The use of TCG gasket is selectively used and it expands the application to wide field.

5. Easy change of condensing capacity by increase or reduc-ing the number of plates.

6. Because of inlet and out let connections at the same side, YX type can be applied not only an total condenser but also to partial condenser.

GX-20

Decreasing the plate thickness due to severe erosion corrosionCracking at the gasket groove Heat exchanger Seawater inlet port hole Wood chips, seaweeds and shellfish are blocking the flow channel, and causing poor fiow in the unit.

FEATURES

GX-21 provides 10mm channel space both for hot and cold sides, so that heat recovery can be performed between hot and cold slurry. GX-22 plate is made by reversing and upside down GX-21 plates.Mixed plate arrangement of GX-21 and GX-22 is named GX-23. It gives the widest channel spacing (20mm) at one side, which is available for large size particles.GX plates have wider depth, larger corrugation pitch and less metal contact points, comparing to conventional plates.

ADVANTAGES

1. Easy to flow throughout between plates.2. GX series provides the widest channel spacing.3. Mixed plates arrangement gives three types of channel spac-

ing.4. It is better performance for slurry, sludge and crystal con-

taining liquid.5. Electrolytic polishing selectively used for food application.

In order to extend the lifetime of the plate heat exchanger, it is important to watch changes in conditions. Frequently observed faults and causes are summarized below. If those faults are detected, please contact us and inform manufacturing number of the unit.
