Turney Center
Correctional Facility, TN
Although the original specification
called for a Bell & Gossett product,
the contractor installed a
competitor’s unit. Within the
first year of its installation, the
facility started to experience air
lock and heat transfer difficulties.
The original air separator device
was enhanced with a coalescing
medium to increase its efficiency
but it just couldn’t get the air out
properly. The competitor’s unit was
taken out and it was replaced with a
Bell & Gossett RL-8. The system is
now operating properly with no air
problems. The facility has operated
without air problems for over
10 years.
