Selection and installation of the
insulation
Selecting the appropriate insulation depends on
the operating method, the installation temperature,
the dimensions and the location of the vessel.
Typically recommended insulation materials are
ProRox
®
wraps (mats) and ProRox
®
flexible and
semi rigid boards (slabs) like the SL 920
NA
,
SL 930
NA
and ENERWRAP
®
MA 960
NA
.
Since vessels are often located outdoors, it is
important to select insulation with a low thermal
conductivity and excellent water repellent
properties. The insulation is usually fastened to
the cylindrical vessels with steel straps. These
should be made from stainless steel and should
be closed with butterfly nuts or quick release
fasteners. The strap measurements and intervals
for cylindrical objects shown in the table on the
next page have proved useful in many projects.
