Jord was engaged to investigate and undertook a comprehensive noise abatement and process performance study to determine means of optimisation.

A combination of low noise cowlings, a modified fan design, upgrading of the drive transmission, a modified fan belt profile, low noise fans and fan tip seals were recommended and accepted.

Jord manufactured and supplied the components and supervised installation and commissioning.

As a result, the noise levels were reduced from 96 dBA to 81 dBA.  Thermal performance was increased and the life of these aging units was greatly extended.
