Plate-Fin Heat Exchanger,
"SUMALEX®"

Our heat exchangers composes of corrugated fin and separation plate which are stacked and brazed. Comparing to the other type of heat exchangers, by enlarged heat transfer area , this type of heat exchanger becomes more compact and lighter. We can produce from large to small heat exchanger, and take flexible material choices, such as aluminum alloy, and stainless steel etc.

Structure

SPP's plate-fin heat exchanger "SUMALEX®" is made by stacking brazing sheet (flat plate) and corrugated fin (wavy plate). Each layer is individual passage.

Features

Plate-fin heat exchanger "SUMALEX®" has the following features;

1Light weight, Compact, and High thermal performance, comparing to the other type of heat exchangers.

Comparing to the other type of heat exchangers, if plate-fin type is applied, your heat exchanger can achieve compact and light weight in general, because heat transfer area is enlarged and heat transfer area per volume becomes large. Especially, in case of gas-gas heat exchange process, heat exchanger which is designed by enlarged heat transfer area becomes significantly compact and light weight.

Model case: Comparison between "Shell & Tube" and "Plate-fin"

In comparison with Shell & Tube heat exchangers, the following benefits are expected for our Plate-fin heat exchangers;

Smaller installation space.
Simplification of support structure for heat exchanger
Reduction in power consumption of compressor

	Shell & Tube	Plate-Fin
Gas outlet temperature	40°C (Cooling water 32℃)	34°C (Cooling water 32℃)
Main unit dimension	400Ø×2400	350×440×900
Main unit volume	0.30m³	0.14m³

Temperature difference : 2 ℃: Running cost improvement: 1%; Heat Exchanger volume reduction:60%

2Best selection from various fin type.

For accommodating various customer requests, we assort about 300 kinds of corrugated fin, and offer most suitable selection for customer specification.

Fin shape

Plain type
Perforated type
Herringbone type
Louvered type
Serrated type

Fin dimension

	Min.	Max.
Height H	2mm	25mm
Pitch P	0.9mm	8.5mm
Thickness t	0.1mm	0.6mm

3Multi fluid heat exchange

Due to structure of plate-fin type, multi fluid heat exchange is possible. You can reduce piping and installation space. (Up to 15 fluid possible)

Passage arrangement - 4 fluid counter flow

4Superior air-tightness / durability

Corrugated fins are all brazed with brazing sheets, and configure integrated structure. They are not only for enlarging heat transfer area, but for withstanding high internal pressure, and provide superior durability. Production with this our original brazing technology and argon-arc-welding provides sound mechanical reliability and air-tightness.
