PTM - The manufacturer

For heavy duty mixers in biogas plants


As a highly specialised manufacturer, we bring many years of experience together with state-of-the-art technology. The result is a submersible mixer for the most challenging situations - the PHANTOM.

The PHANTOM is the product of our in-depth application knowledge in the biogas sector, and provides a comprehensive solution for your biogas plant. The PHANTOM combines the utmost efficiency and maximum durability in one product for the first time. Well-thought out and tested down to the last detail, a shielded mechanical seal in tandem execution provides for reliable sealing, for example. The motor with high reserve also resists even increased temperatures without a problem, providing a solution to the challenges posed by high-fibre and high-viscosity media.

Propellers in submersible mixers in biogas plants naturally sustain a lot of wear. This is why the PHANTOM is equipped with a monolithic propeller made of a high-performance plastic. Clearly superior to both conventional metallic and also glass-fibre materials, it delivers the required high level of efficiency and reliability even over a long period of use.

PHANTOM - our goal is your success!

1000 | 1400 | 2500




A hybrid mixer for biogas applications which fills the hydraulic gap between the slow running 2500 and the faster running Phantom 1000. Thanks to its high thrust forces it can therefore contribute to the formation of a global tank flow in biogas plants.

At the same time, however, the propeller, which has been designed by hydraulics experts, also generates the turbulences required to prevent floating layers. This mixer is extremely versatile over a wide range of applications. For example fast runners with motors up to 18.5 kW can be replaced by a Phantom 1400 with 7.5 kW nominal output without thrust force losses, enabling energy costs to be reduced by up to 60%.

A change of mixers can usually be made on the existing installation set. As the Phantom 1400 acts as a flow accelerator as well as a source of turbulence with lower energy consumption, it can be used as the sole mixer in fermenters for example in 75kW biogas plants.
