Gasket Plate Heat Exchangers

What is PHE?

Plate Heat Exchangers have been used in all kinds of industries as compact heat exchangers with maximum efficiency.
The Plate Heat Exchanger is a heat transfer equipment consisting of a pack of heat transfer plates, compressed by frames and tightening bolts. Heat transfer plates are made by pressing thin sheets of corrosion-resistant metal such as stainless steel or titanium, setting them with seal gaskets and hanging and piling them on the guide bar. Then, plates are tightened with bolts between the fixed frame and the movable frame.
Here, there is a certain 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.

Features and advantages

Our plate heat exchanger has excellent characteristics such as high-energy efficiency, compact size, easy maintenance, easy adjustment to capacity change, and relatively low capital investment.
Our wide range of sizes, plates, gasket materials, and add-ons allows you to flexibly and creatively design and configure according to the applications, from the simplest tasks to the most demanding performance and documentation requirements.

High Thermal Efficiency

The press-formed patterns provide a high heat transfer coefficient by a turbulence flow.

Lightweight and Smaller Footprint

Less weight and compact size can be realized by the thin heat transfer plates and the small holding volume.
These features provide simple installation work with low cost.

– Compressed thin heat transferring plates
– Limited fluid capacity
– Smaller heat transferring surface area

Quick Start-up

Smaller holding volume makes quick start-up of the process.
Limited fluid capacity per unit allows quick operation start up, and also possible to correspond to changes in operating conditions with high precision.

Easy maintenance

Simple Assembly and disassembly for inspection and maintenance by loosening the bolts and nuts.

Modular Construction and Design Flexibility

Flexibility to easily implement various thermal programs and future expansions/modifications.

Prevention of Liquid Inter-mixing

Gasket grooves protect it from direct contact with the liquid.
The double-seal gasket with drain avoids any mixing of the two liquids preventing performance deterioration in case of a gasket failure.

Plates & Special Plates

The plate pack is the active part of the heat exchanger where the heat exchange takes place.
Each heat transfer plate is a thin sheet of corrosion-resistant metal such as stainless steel or titanium.

The surface is corrugated to various patterns to increase its strength and surface area and the corrugation makes high turbulence which achieves a high heat 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.

Plate Element Types

Wave Corrugated Pattern

The wave-corrugated pattern is also known as the washboard pattern.
There are few points of metal contact between the plates, allowing liquids containing fibres and sludge to easily flow without clogging.

Herringbone Pattern

The “herringbone” pattern was named, as the V-shaped press grooves resemble the bones of a herring.
Pilling the V-shaped pressed plate and rotating it 180 degrees in an alternating pattern can create many contact points.
This ensures high-pressure resistance and the complicated flow path formed by the V-shaped press grooves delivers high heat transfer performance. Moreover, the thin plate reduces the heat transfer resistance, and all this results in a 3-5 times better heat transfer performance than the S&T heat exchanger.

Combining different types of herringbone can optimise this mixed arrangement and decrease the heat transfer area.
Thus, results in an optimal technical / economical solution.

Special Plates

Aside from the concept of an individual heat transfer plate, we also offer the following special plates with outstanding performance to meet more diverse and advanced requirements.

Gaskets  & Special Gaskets

Gaskets used in plate heat exchangers need durability to withstand a wide range of liquid qualities and temperature / pressure conditions.

Our original gaskets are manufactured under very strict quality control with the highest low material quality to support a wide variety of applications.

Combined with a careful gasket material selection, high performance and gasket durability can be expected.
