Suzhou Sehenstar Energy Technology Co., Ltd.

Model Number: SWS-#5832 Brand Name: SeHenStar Key Specifications/Special Features: SWS heat exchanger is used in heat transfer process of wastewater or other impurity fluid, consists of concentric thermo plates that are continuously cleaned with attached brushesContinuous cleaning of the plates ensures optimum effect from the heat exchanger, as the dirt is kept at a minimumBrushes make sure that particles do not burn onto the thermo plates which also has positive effect on the life of the productSWS heat exchanger is built as vessel and thus allows for heat exchange in situations, where the process fluid flows in an uneven steam or even stops for shorter or longer intervalsFeatures:Self-cleaning unit with brushes with an adjustable speed of rotationHighly efficient due to the movement of the brushes, which create better turbulence and thus increased efficiencyEasy to inspect
Available in various steel qualities
Variable volume of vessel and number of rings depending on the application

Applications:
Heat recovery in connection with swimming pools and the like
Cooling of waste water or sludge
Discharge air from paper machines
Chemical high-viscosity fluid heat transfer
And other fluids with heavy fiber content

Application examples:
One paper factory production process requires very large volume of water drawn from a river, in winter, incoming water is relatively cold, arriving at temperature of approx 5C
On other hand, factory production process wastewater temperature is up to 55C, which is much too high for the biological wastewater treatment to follow
Microorganisms die if the water is too hot
In such cases, best energy-saving solutions of using wastewater to heat incoming water while reducing emissions to below 30 degrees

Final SWS heat exchanger performance:
Heat output: 1mW
Flow rate (wastewater side) 65m3/H
Flow rate (cooling water side) 55m3/H
Pressure loss (wastewater side) 0.01 bar
Pressure loss (cooling water side) 0.40 bar
