N.E.T. have specialised in the repair and maintenance of Allspeed Kopp variators  for over 30 years.
 Our engineers have been formally trained by the gearbox manufacturer ensuring all our repairs are
done to their own exact standards.

The Allspeed Kopp is a very simply designed variator using cones & drive balls to transmit power
from the input to the output via two pressure devices.

Modern technology demands the ability to change speeds frequently,
 whether by manual methods or automatic control systems.

The Allspeeds Variator is ideally suited to these requirements,
as the control mechanism is light, positive and extremely accurate.
 Predetermined speeds can be quickly selected and accurately maintained.

The unit is also totally enclosed and therefore
suitable for use in dusty or wet environments or
in hazardous locations demanding explosion proof work.

The Kopp variator offers all the benefits of similarly designed friction variators, but with the added
advantage of a step less speed variation of 9:1.
This means the output speed ranges from one third to three times the speed limit.
Allspeeds Variators offer speed ranges from 11:1 variation and input powers 0.18kW to 25kW.
