・Strong on customized solutions
・Low maintenance cost due to easy access
・Compact high-efficiency heat exchanger (CHE)
・Design experience since 1961
We have prepared 2 or 3 types of spirals for each of the three series.
Type 1 has two concentric spiral channels, one for each fluid.
The spiral channels provide optimum heat transfer and flow conditions for a wide variety of fluids, while keeping the overall size to a minimum.
The fully countercurrent system(KSH-1) is able to exchange heat even if temperature difference is extremely close.
Spiral is very good at using with fluids that tend to cause fouling. Single channel geometry reduce the fouling, and it called “self-cleaning”
Self-cleaning means that when fouling occur in spiral channel, taking it away from. Because the entire flow have to pass through fouling section.
It means that velocity of fouling-section increase. So scrubbing effect will happen.
Spiral flow passage easily creates turbulent flow.
Optimum flow speed can be gained by selecting the most suitable spiral channel.
High Overall Heat Transfer Coefficient can be achieved.
Generally, when install the spiral type, to cut down maintenance cost.
Compare that with any other heat exchanger
SHE equipment volume is far compact comparing to Tubeler Heat Exchanger.
Plant space can be saved and plant initial cost can be saved.
