Made with high efficiency, heat resistance, and pressure resistance features. HISAKA full welded plate heat exchanger is able to replace shell and tube heat exchangers on various applications which were impossible for a gasket plate heat exchanger.
Product Features
High transfer coefficient due to its special corrugation plate pattern.
Support high-temperature application up to 350°C.
Gaskets only apply for side cover, thus very low OPEX.
Option for multi-pass design by installing baffle to obtain performance close to counter-current flow.
Welded Plates expand the limits of plate heat exchangers
Welded plate heat exchangers offer higher heat resistance and pressure resistance to support under severe conditions of 350 C and 3.5 MPaG
Welded plate heat exchanger comes with a variety of plate gaps and flexible design to support a wide range of applications.
How do you clean a welded plate heat exchanger?
Disassembly Cleaning with Water Jets
Removing the side cover plates allows for easy cleaning. After disassembling, the water jet cleaning can remove the scales and the internal foreign material affixed to the heat transfer plates, restoring performance to almost that of a new product.
As the plate pack consists of heat transfer plates welded on two sides in an alternating pattern for a cross flow structure, cleaning fluid can flow through the plate gaps open on both sides to wash away scales inside the plate gaps and affixed foreign material.
Also, the option for using the hinge type side cover makes maintenance even easier.
Cleaning in place (CIP)
Hisaka offers CIP using Plate-Clean at the customer’s site if disassembly and cleaning are not possible. Before scaling, CIP with Plate-Clean can restore performance by removing scale through washing and dissolving. This is effective in prolonging the maintenance period of the PHE.
Fully Welded Plate Heat Exchanger Working Principle
How Does a Fully Welded Plate Heat Exchanger Work?
Heat transfer occurs when there's a temperature difference between two mediums. A fully welded heat exchanger utilizes crossflow on the heat transfer section between two different temperature fluids (high & low). With fully welded, better efficiency and lower heat loss can be achieved. More so, it is also free of gasket maintenance.

Comparison Table
Product Name
Fully Welded Plate Heat Exchanger
Shell and Tube Heat Exchanger
Size
Compact and light, due to the design of heat transfer plate.
Made with a bundle of heat transfer tubes that is contained inside a cylindrical shell.
Cost
Fully welded heat exchanger is built with compact structure, thus it is smaller in size, where lesser material is required to build.
Bigger in size which required more materials to build, yet bigger footprint required.
Performance
Heat transfer coefficient is around 2,500 W/m².K
Heat transfer coefficient is around 1,500 W/m².K
Maintenance
Can be clean with just a small crane to lift the door covers and water jet cleaning can be applied to the plate.
Due to its design and size, extra lifting, manpower and dismantling work is required for maintenance.
HISAKA Free Flow series with corrugated plate design provides high heat transfer while minimizing clogging issues.
Advantages:
Maximum of 25mm gap per Free Flow channel.
High-pressure resistance by combining corrugation contact points and spot weldings.
Optimum cleaning access for free flow side.
Highly effective condenser.
HXEU Condenser
Multi-purpose HXE model utilized embossed plate type that connected 2 plates to create a channel. One side is free from metal contact that will allow Free Flow Fluid such as vapor and gas to flow smoothly for condensation process.
Advantages:
Reducing thermal stress - Plate pack only welded on 1-side of the wall.
Suitable application for high-temperature difference between hot and cold side.
Both utility and vapor sides can be cleaned easily.
Plate cassette can be easily replaced or repaired if damage occurred.
Maximum of free flow gap up to 40mm.
Can opt for "Sight Glass" to monitor the inside condition of the unit.
