TM Micro Turbines  

Mavel’s TM Modular Micro Turbine (“TM Turbine”) is designed for sites with low flow and low head conditions. Easily installed, the TM Turbine utilizes siphon technology to capture the energy of the water utilizing a Kaplan-type runner with four manually adjustable blades. The runner is connected to an asynchronous generator directly or by a belt drive. This allows for turbine and generator speeds to be optimized for the site condition. The TM Turbine does not require an enclosed powerhouse and can be installed directly on support brackets attached to the weir structure. Over the past twenty years, Mavel has installed over 65 TM Turbines at sites in Bulgaria, Czech Republic, Finland, Germany, Japan, Italy, Latvia, Poland, Slovakia, Slovenia, Ukraine and the USA.


The TM Turbine’s features include:

modular design
no powerhouse requirement
manual blade adjustment
siphon technology

robust construction
short delivery times
proven performance
