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.
