Circulation Soft Water Cooling System ( air-water cooler)


Mode GPKL-II circulation soft water cooling system adopts closed cooling tower structure. Cooling soft water is flow in sealed water tank and cooling pipes. The inner circulation soft water is cooled by overhead fan and water-spray method using the principle absorbing heat when evaporation. The spray water circulate inside and closed cooling tower`s heat dissipation pipe, spray-water spray at pipes` surface through spray system, some heat is taken by dissipation and soft water temperature inside the pipe go down accordingly. The cut board stops water in hot air and un-evaporated water, make them flow through PVC heat exchange layer, the water in the layer is down by air, then temperature goes sown and fall down to the bottom of the tower.

Apply range: 60 kW –1200 kW induction heating power supply.




  • Energy saving: Low investment, small volume, compact frame, convenient installation, easy transfer and without any investment on building cooling pool and cooling tower.

  • Water saving: Water saving 95% compared with directly water supply cooler.

  • Electricity saving: Electricity saving above 90% compared with compressor cooling mode.

  • System adopts sealed soft water circulation, no scale, no jam.

  • Excellent material, advanced manufacture technics, high heat dissipation efficiency. The equipments dissipation parts adopts high quality of brass & aluminum compound pipe with advanced manufacture technics, brass outer pipe connects hydrophile aluminum platinum fin board in expanding joint mode. Such structure has very large heat dissipation area, high dissipation efficiency, its dissipation ability is far more better than pure aluminum pipe, steel pipe and steel & aluminum fin board.

  • Best cooling effect due to wind cooling and spray water complex cooling mode. Low temperature in winter, single air cooling can meet production demand, no need to run spray; high temperature in summer, also high water temperature, wind cooling plus spray mode can be used which guarantee some key parts wont damage due to over high water temperature in summer  such as SCR, capacitor, reactor, induction coil etc. Therefore prolong using life-span of equipment.
