Precision Cooling
For Business-Critical Continuity
Liebert DS models incorporate an automatic self-tensioning
motor base which keeps constant tension on belts while
maintaining good sheave and pulley alignment.
As part of the improved air delivery system, Liebert
developed a new belt offering for the DS. This improved
belt design increases belt life and reduces belt dust.
Key Features
Cord tensile strength 18% stronger
than a conventional belt, which
provides greater strength and
superior stretch resistance.
100% neoprene rubber compound
increases belt strength while
reducing belt wear and improving
flexibility.
Belt temperature runs cooler with
better heat dissipation, improving
belt life.
Liebert belts are machined,
matched and tagged as a set
for optimal life performance.
Belt design and material reduce
belt dust.
Polyester cords maintain
extreme belt load and
shock without stretching.
Four fabric plies top and
bottom relieve stress on
load-carrying cords for
added flexibility.
100% neoprene rubber
compound supports cords,
dissipates heat and provides
oil, heat and ozone resistance.
Raw-edge belt sidewalls grip
pulleys better to minimize belt
slip, noise and drive vibration.
