VTHR range
The VTHR (Vertical Tubular Hydro) range by Leroy-Somer is perfectly calibrated for small hyd
The Leroy-Somer Vertical Tubular Hydro Range has been designed for small hydro plants looking for compact & reliable equipment.
Balanced construction
The steel welded construction of the tubular reinforces the overall structure, and together with the flat brackets design guarantees a compact, stable product.
As a result, all VTHR products Balancing Class is G1 according to ISO 1940.
Controlled Performance
The VTHR products have been optimized for the specific constraints of small hydro environments.
- Close monitoring of speed and heating through built-in sensors
- The D510C digital AVR allows for precise fine-tuning of operational parameters
- Vibration sensing can also be included as an option
Clever commissioning
At your request, the alternator can be fitted with a special device that facilitates uplifting operations. This simple approach was first introduced by Leroy-Somer and allows to put the alternator in vertical position with just one lifting device.
