Repair of Chill / Heat Transfer Rolls
Thermal rollers (aka “Chill Rolls” or “Heat Transfer Rolls”) represent the top tier in roller technology. They are required to maintain a precise temperature consistently across the entire rollface, often under harsh conditions, while also providing an unblemished smooth face finish.
Occasionally, over a long lifespan, one of these elements breaks down. That’s a good time to call Menges Roller.
We offer a wide variety of repair and maintenance services for thermal rolls, from shell replacement and refinishing to inner-cavity acid flushing, as well as journal repair or replacement.We can even restore your current roller to like-new condition or re-engineer it to perform for a new application.
We can repair or replace the coating or cylindrically grind and re-plate with whatever finish you require. We also repair leaking or clogged rolls, as well as put new journals on existing
Repair & Maintenance Services for Thermal Rollers
This steel-shelled chill roll is being cylindrically ground
in-house and will be re-plated in mirror- finish chrome.
This is a common service for chill rolls, and is often
combined with a regularly scheduled acid flushing
One of our key specialties is larger, longer rolls. This applies
to new fabrication projects as well as refurbishing existing
rolls. Over 20 feet long, this double-shelled heat transfer roll
is being cylindrically ground to a low Ra after being plated.
Especially for rolls that have never been acid flushed, the interior cavity can become clogged, reducing fluid flow and offering poor thermal transfer. The Menges Roller team can rebuild these poor-performing rolls by removing
the outer shell, fabricating new baffles and components, then installing a completely new outer shell. Plating,
such as chrome or nickel is then applied.
With this process, the roll will perform like new and represents about a 40% savings versus the cost of
fabricating a completely new roll.
Never Acid Flushed:
This large double-shelled roll was never acid flushed.
This resulted in deposit buildup, low fluid flow, and poor
thermal conductivity, which affected the customer’s
product quality. An inner-shell rebuild was then required.
The inner shell was reground and balanced, new spiral
baffles were installed, and here the roll awaits its new
outer shell. Regular acid flushing would have prevented
this extensive rebuild. However, once finished, it will
perform like new.
Acid Flushing - An Important Maintenance Procedure
Chill & heat-transfer rollers that are not performing optimally may be clogged with a variety of compounds, including rust, calcium deposits, congealed chemicals and hardened particulate matter. This can severely affect the roll’s performance, significantly decreasing its thermal conductivity. Pumps and machine accessories could also potentially be damaged.
But Menges Roller can help.
We offer a unique acid flushing service that breaks-
