Supreme Air Separation for Commercial Systems
• Higher capacities than coalescing designs.
• Less pressure loss than coalescing designs, greatly reducing overall pump operation costs.
• ASME stamped.
• Patented tangential flow-through design maximizes air separation efficiency.
• Proven reliability – Rolairtrol has successfully increased system efficiencies for 40 years.
• Buffer tank ability – The Rolairtrol contributes to meeting the minimum loop volume.
• Backed by Bell & Gossett’s 90 years’ experience in hydronic, HVAC and plumbing systems.
Rolairtrol is a patented air separator with significant
advantages over all other types of air separators.
It removes air that commonly causes problems in
commercial hot and chilled water systems, and
provides air-free flow, improving system efficiency
and performance.
The Rolairtrol removes entrained air from the system
fluid through time-tested centrifugal action. It
provides maximum air separation efficiency through
a combination of centrifugal force and velocity
reduction. Unwanted air is separated by the
differences in density between air and water.
Its tangential design creates a whirlpool inside the
vessel, sending denser air-free water to the outer
section near the shell, while the separated air
migrates to the low-velocity center where it is drawn
to the air collector. The separated air is removed from
the system through the Hi-Capacity Air Vent in an air
elimination system, or directed to the compression
tank in an air control system.
A removable strainer is standard on the “R” model,
reducing the quantity of components required for
installation. The strainer has a free area of not less
than five times the cross sectional area of the flange
connection size. All debris that is collected within the
strainer can be removed from the vessel through the
blowdown connection on the bottom of the vessel.
In chilled water applications the Rolairtrol acts as a
buffer tank to increase the chilled water volume. The
increased water volume of the Rolairtrol improves
chiller water temperature control, stabilizing system
operation, and reducing compressor cycling
compared to chiller loops with insufficient water
volume.
Patented in 1951, the Rolairtrol has been the best
overall air separator in the commercial HVAC
market with respect to initial cost, effectiveness,
maintenance and operating cost for over 40 years.
