PTM is a highly-specialised manufacturer, we combine many years of experience with high technology. The result is a submersible mixer for the toughest applications – The PHANTOM. The PHANTOM is the product of our extensive application know-how in the biogas industry and provides a comprehensive solution for your biogas plant. Naturally, the propellers of submersible mixers in biogas plants are subject to high wear. For this reason, the Phantom is equipped with a monolithic propeller made of a high-performance plastic. Clearly superior to both conventional metallic as well as glass-fibre materials, it delivers the required boost, highly efficient and reliably, even over a long period of use.
