\n Submerged mixer<\/span>\n
THS Submerged Mixer<\/h2>\n
The THS line is HIGRA's submerged mixing solution, designed for robust homogenization in tanks and ponds. With an axial rotor and high thrust diffuser, it creates a directed jet that recirculates the useful volume, promoting macro and micromixing with low energy consumption. In inclined arrangements, the jet describes a downward trajectory, sweeping the bottom and preventing sedimentation. Compatible with frequency inverters and with or without oxygen injection. <\/p>\n\n
