Endurance E-3120 & E-4660 Spring Tubes Upgrade

Endurance E-3120 Wind Turbine Spring Tubes Upgrade

A key part of the safety system on the Endurance E Series turbines is the blade spring tubes.

This is an essential part of the mechanism that pitches the blades to aerodynamically restrict rotor speed in the event of a brake failure.

DC21 are pleased to offer a Serenity Wind spring tube upgrade to all E-3120 and E-4660 models.

These spring tubes come with a 5 year insurance backed limited warranty.
