CHC590 Rotary heat exchanger solves the problems inherent in the heat exchange with liquids loaded with fluid and solid pollutions, specific features of the heat exchanger include the capacity of working without filters with especially highly polluted liquids with solid and chemical load of all types. Mainly used in textile wet process machine fabric washing phase.

Working Theory

feed the hot polluted water in the heat exchanger and then drainage, make the supply fresh water become hot water , and then feed the hot water in the washing chamber and padder for spraying fabric, make washing chamber water temperature rise, then save steam comsumption.


Ÿ  Compact structure, small space occupied

Ÿ  All SS304 material, 3mm thickness chamber sheet, impeller 1.5mm thickness

Ÿ  A central axle formed by a set of shaft-mounted fixed disks, fresh water flows inside the disks in a labyrinth circuit, the axle is submerged in a tank which constitutes the polluted water circuit and

which allows the passage of polluted water outside the impeller, the central axle is driven continuously by a small motor that generates turbulence which has two well defined purposes: increasing the efficiency of the heat exchanger whilst keeping the polluted water passage sections  as wide as possible.

the generation of a water flow departing from the centre of the axle and travelling towards the outside of the impeller which washes the exchanger to keep it clean.

Ÿ  Self-cleaning properties thus assuring the elimination of sealing and stoppages.

Ÿ  Thermo-meter temperature display both entry and exit of polluted water and fresh water .

Technical parameters

Overall size: ~3700mm×740mm×720mm. Fresh water entry and exit dia.50mm Polluted water entry and exit dia.100mm Exchange area: 21m2

Fresh water capacity:180L Polluted water capacity:1000L Exchange efficiency: 70~80% Design capacity: 4~8ton/hr Working pressure:0.3MP

Return of investment

One set CHC590 heat exchanger can meet 5~8 pcs washing chamber water supply, 4 months can take back the machine cost(calculated on the basis of 20hr/day,20working days/month; steam price 20usd/ton.)
