Helical ribbon impeller

for agitators

PRIMIX manufactures and supplies products that vastly improve the heat transfer in heat exchangers. Pipe heat exchangers are applied in the industry for cooling or heating products, however, with a viscous product the heat exchanging ability of this type of heat exchanger can deteriorate significantly and therefore usage becomes uneconomical. By using mixer element strands the capacity of these systems can be improved. PRIMIX manufactures mixer element strands but also twisted tapes or ribbons. -CheckFor increasing the system heat transfer capacity -CheckMixer element strands from 4 mm diameter -CheckTwisted tape up to 100 mm diameter Mixer element strands When cooling or heating highly viscous products, the risk of tunnel effects is high. Because of the formation of a boundary layer, the product near the inner wall almost comes to a stand still; the consequence is that the heat transfer is restricted. There is a real chance that because of fouling the exchanger will continue to clog up with product. Due to the occurring differences in speed, there will also be a large residence time spread. By applying PRIMIX mixer elements strands, the resulting boundary layer is reduced to a minimum; the result is that the stationary boundary layer is broken and there is a continuous replenishment and addition of new product, which will have a positive effect on the heat transfer. Also, the residence time spread will be better because the mixing improves. By using PRIMIX mixer elements strands the system pressure drop becomes larger; your feed pump must be suited for this naturally. Heat transfer improvements of 40 % with respect to an empty pipe are no exception.
