-
Plate edges are slit to width after welding and
coined to provide a rounded edge which enhances paint adhesion, precludes
moisture accumulation and inhibits corrosion.
-
Trantech welded header radiators are 100%
self-draining.
-
The slotted header of welded Flexoplate®
radiators is 3-1/2, 4 or 5 O.D. steel tubing which provides
strength for a self-supporting assembly. The area of the header slots is
maximized to provide a full flow of oil through the rippled plates.
-
During the plate-to-header welding operation,
the insides of the radiators are purged with an inert gas to eliminate weld
scale.
-
Demountable radiators are fixtured as a
completed assembly for accurate positioning of the mounting flanges.
-
All Trantech radiators are available with a
demountable option.
-
Trantech radiators are 100% leak tested.
-
IHR radiators are chemically cleaned internally
and externally, and then power phosphatized to enhance paint adhesion and
corrosion resistance.
-
Welded header radiators are painted internally
with epoxy primer to ensure cleanliness and to enhance corrosion resistance.
-
Typical external paint coverage will include an
ultra durable polyester powder coating which meets requirements of ANSI
C-57.12.28 with respect to adhesion, salt fog, humidity, Q.U.V and Taber
abrasion.
