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




The most efficient mixer for biogas applications where turbulence generation combined with high thrust is required.

The Phantom 1000 is used mainly for mixing the substrate, for eradicating or preventing floating layers, as well as for breaking up sinking layers.

It is the ideal complement to the Phantom 2500 in fermenters.
