Structure of Plate Heat Exchager
Since we delivered our first domestically-produced device in 1953, HISAKA plate heat exchangers have been used in all kindsof industries as compact heat exchangers with maximum efficiency. In order to meet more diverse and more sophisticatedneeds, we have arranged a rich variety of models, from small models of 0.18 m2/unit to large models up to 3,400 m2/unit.

■ Basic Structure■ Heat Transfer Plate

Heat transfer plates are made bypressing thin sheets of corrosion-resistant metal such as stainless steel ortitanium, then set them with seal
gaskets and hang and pile them on theguide bar. Then, plates are tightenedwith bolts between the fixed frame andthe movable frame. Here, there is acertain gap between the heat transfer
plates that allows liquid to flow. The
liquid inlets and outlets are in the fixed
frame or the movable frame.

Each heat transfer plate is corrugated to various patterns toincrease its strength and surface area. Furthermore, thecorrugation makes high turbulence and thereby achieves highheat transfer coefficient. Portholes are formed in the plate's four
corners. The gasket is set into the groove around the plate edge
to seal in the fluid. (Refer to P7.)

Plate Element Types

Features■ High Performance■ Easy Maintenance

The plates are specially selected from various patterns so as to achieve optimum heat transfer area and cost effective heat

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 a highly
turbulent flow. This is one of thereasons why plate heat exchangers
have such a high heat transfer coefficient. In addition, this turbulent flow
also acts to prevent scales on theplate surface.

Loosening the tightening bolts allows for simple disassembly.
The heat transfer plates can be easily inspected visually, andcleaning is easy.

exchanger type for each requirement. These plates include the corrugated pattern EX and FX series, the herringbone pattern
RX, UX, LX, SX, and CX series, and the specific pattern GX and YX series.

■ Steam available as the heat source

The corrugated pattern is also called thewash board pattern. It has less metal
contact points between plates and allows
for even liquids with fiber or sludge contents
to flow easily without blockage. The FX
series was developed exclusively for foodapplication even beyond the conventional
corrugated pattern. (Refer to P16)

The use of a synthetic rubber gasket with a special composition
enables the use of steam as a heat source, that is, an operating
temperature range up to 180°C.

■ Minimal heat radiation■ Smaller Footprint
The lightweight and compact construction reduces theinstallation space to 1/3 and the weight to 1/10 of S&T (shell &tube heat exchangers), respectively. In addition, the lightweight
and thin heating plates and less liquid hold facilitate theinstallation work. The Plate Heat Exchanger can be disassembled
for cleaning without piping work, while the S&T heat exchanger
needs additional space for drawing out the tube bundle.

Heat radiation from plate pack is blocked by the gasket, with
only a minimal amount of heat radiation from the thin fin-shapededge. Also, as the front and rear of plate pack is connected to
the frame of each through an air layer, the heat radiation isminimal. Except in cases with an extremely small number ofplates, it is less than 1% of the heat exchange amount.

■ Short delivery time
We have a stock of plates in standard materials (SUS304 / 316
and TP270) and have standardized the construction to achieve
short delivery time. However, regarding special materials suchas high nickel alloy, NNCP, TP270-Pd, and the like, pleaseinquire.

■ Prevention of Liquid Inter-mixing
Special consideration is taken for the gasket so as to protect itfrom direct contact with theliquid. Furthermore, the gasket
is a double-seal type so as topermit liquid draining outside
the exchanger even in a case ofa liquid leak caused by its
deterioration.

■ Corrugated Pattern

The "herringbone" pattern was named as
the V-shaped press grooves resemble thebones of a herring. There are numerous
contact points by pilling the V-shapedpressed plates, turning them 180° in analternating pattern. This ensures highpressure resistance, and also the complex
flow channels formed by the V-shapedpress grooves get high heat transfer
performance. Furthermore, including thedecreased heat transfer resistance due tothe thinner plate results in heat transfer
performance three to five times higher
than that of S&T heat exchangers.
A herringbone pattern with a W-shapedpress groove is called a "double
herringbone" and is an improved versionof the V-shaped herringbone.
The"lightning
herringbone"isaherringbone for higher NTU duty.

Double herringbone

There are two types of herringbone pattern plates; one where
the V (W) angle is obtuse (H-plate), and one where it is acute(L-plate). Combining H-plates and L-plates can allow for three
types of different flow channels; H-H, H-L, and L-L. Our optimal
design method which combines plates, known as the "mixed
arrangement," can decrease the heat transfer area by approx.
25% compared to designs with a single plate.

Gaskets

Plate Heat Exchanger Lineup

Gaskets used in plate heat exchangers must have durability in various liquid qualities and temperature / pressure conditions.

Semi-welded Plate (WX)

Hisaka has prepared the following gasket materials in order to support a wide variety of applications.

Gasket for cassette interior(ring gasket)

Special material: FPM (fluororubber), silicon, PTFE cushion gasket

2. NEW-EPDM (N-EPDM)
Usually, EPDM gasket is selected either for hightemperature or aggressive fluid applications. Although
EPDM gaskets are high quality, rubber gaskets lose
elasticity as time passes. A cutting edge N-EPDM
gasket, newly developed by Hisaka, was introduced.
The N-EPDM gasket improves both the heat andchemical resistance. The life-time is two times higher
than conventional EPDM. Originally invented specificallyfor the CO2 chemical recovery process, the N-EPDM isuseful for other applications with many advantages.

❶ The dual wall design prevents any leaks from going farther
due to the air gap and the second plate. In case any one ofplates were to fail, the leak can be detected from outside
because of leaking through the gap of the plates.
❷ To prevent intermixing of the fluids, “Double seal gasket” (refer
to P6) system is used. Any leakage of fluids across the gasket
can be detected from the outside because the liquid escapesfrom the units.

■ Applications❶ Cooling of transformer oil, which might explode if mixed with thecooling water❷ Cooling of lubrication or hydraulic oil, which can damage therotator or hydraulic equipment if mixed with the cooling water❸ Heating / cooling of food processing, where there must be no
mixing of foreign materials in the product❹ Heating / cooling of fuel oil (marine gas oil: MGO) where fatigue
breakdown due to highly frequent pulsation❺ Heating / cooling in bio-process where the process fluid may
cause environmental pollution❻ Heating / cooling between fluids where mixing can cause asudden chemical reaction or generate environmental pollutants
It is normally necessary to install two heat exchangers where it isdangerous if fluid A and fluid B are mixed. However, with the dual
wall plate, this is possible with just one unit.

Fluid A

Fluid A▲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 E xchangers can beapplied in a wider variety of applications than before
due to the chemical resistance and the durability ofPTFE. Due to the elastic core of the TCG gasket, it
does not require strong tightening torque during theassembly of the unit. Thus, it reduces the risks of platedeformation by over tightening. A TCG gasket can beused for one side only, if the noncorrosive fluid is
running in the other side where a conventional gasket
can be used.

The above compares the sealing performance of the conventional EPDM and the
NEW-EPDM. The NEW-EPDM can realize a better heat resistance compared to theconventional EPDM and achieves long time operation.

These plate gaskets do not need glue. The slit-in gasket
is especially recommended for those applications
where frequent replacement of the gasket is required.
Further, without the glue, glue odor is reduced. The
slit-in type gasket is suitable for applications such as
water treatment or food processing.
(D-plate gaskets and distance piece gaskets use glue.
Also, some plates do not support slit-in gaskets.)

Cleaning In Place (CIP)

Disassembly and cleaning a PHE makes it possible to remove hardscale and clogging matters and to recover performance to nearly
the same level as new. However, if disassembly and cleaning are notpossible, HISAKA offers CIP using "Plate-Clean" at customers' site.
Before scaling, CIP with Plate-Clean can restore performance byremoving scale through washing and dissolving. This is effective in
prolonging the disassembly cleaning cycle of the PHE. This iseffective for extending the disassembly cleaning cycle of plate heatexchangers.

SEA WATER APPLICATIONS
A reliable solution for
Sea water Application deliveredby professional manufacturer of plate heat exchangers.
When sea water is utilized with plate heat exchanger, the adherence of marine organisms, algae, shellfish, and dust in sea water
into the plate heat exchanger and cause clogging, increased pressure drop, decreased flow rate, and insufficient performance.
Therefore, stable long-term operation of plate heat exchangers can be achieved by taking anti-fouling measures to prevent
adhesion of marine organisms and anti-debris measures to prevent clogging due to foreign materials in sea water.

By inserting an inner strainer into the port hole of the plate heat exchanger,
foreign materials such as sea water dust and algae is removed. During operationof the plate heat exchanger, the sea water inlet and outlet are reversed byoperating the valve to reverse the normal sea water flow, thereby blowing out
foreign materials accumulated in the inner strainer.

Foreign materials in
sea water are removedby the element, andthe filtered sea waterflows out from inside
to outside of element
and is delivered to theplate heat exchanger.

■ Structure
Punching metal elements remove foreign materials such as algae, shellfish, and dust
in sea water.
By switching the sea water flow direction in the element with a butterfly valve, foreignmaterials in the sea water accumulated in the element are discharged byback-flushing.
■ Features❶Use of cylindrical punching metal allows a lager filtration area.
❷Back-flushing is automatically performed using the differential pressure and timer
setting.
❸Back-flushing requires 10% of the flow rate of sea water required for normal
operation, allowing back-flushing to be performed during normal operation.
❹The element can be opened and cleaned without removing the main pipe during
maintenance.

HCS series Cyclone type strainer■ Features❶Use of cylindrical punching metal allows a lager filtration area.
❷Cyclone flow reduces adhesion of foreign materials on the element due to its
self-cleaning effect.
❸Since the drive unit is only the discharge valve, the risk of drive failure du todamage or foreign materials adherence is reduced.
❹The element can be opened and cleaned without removing the main pipe during
maintenance.

Foreign materials in the
inner strainer are
discharged by switching
the valve to switch thenormal flow to theback-flushing flow.

After installation

Fungi and juvenile shells are killed when the environmental temperature rises
due to the circulation of hot water, and even mussels, which are highly
heat-resistant, are killed in 10 minutes at 45°C and in a few seconds at 50°C.
Using this effect, 60°C hot water is kept in the plate heat exchanger for acertain period of time to prevent fouling by marine organisms.

■ Features
This is an environmentally friendly and pollution-free antifoulingtreatment, as no chemicals are used, eliminating the need forchemical control.

Operation flow

Easy

The required utilities are water, compressed air, steam, and electricity
only, and there is no need for concentration control or replenishment
processing required for chemical injection.

Economical

Regular cleaning leads to reduction of disassembly andcleaning work, which can reduce downtime of operation.

Ecology

By sea water is flown from the contact direction of the shell body, a cyclone flow is
generated outside the punching metal element, and foreign materials in sea water
are removed by centrifugal force.
Foreign materials accumulated in the shell are discharged by opening the discharge
valve.
Approximately 10% of the total flow rate can be discharged at all times and it can be
improved the operating performance of discharging foreign materials.
