The <strong>Spirax</strong> <strong>Sarco</strong> units (Strainers,<br />
Float & Thermostatic Steam Traps with<br />
SLR feature, Sight Glass, Air Reservoir<br />
with Air Vent) provides for the best<br />
drainage of condensate and noncondensibles<br />
from rotating cylinders.<br />

The steam traps are often located at<br />
one end for ease of maintenance,<br />
with long pipes connecting them to<br />
the drainage points. If steam-locking<br />
is a problem in these long pipes,<br />
then a Float / Thermostatic steam<br />
trap with a steam-lock release is the<br />
best selection. The beds should be<br />
air vented at points remote from the<br />
steam entry. Steam s<strong>up</strong>ply lines to<br />
ironers should be drained, ideally<br />
using a separator.<br />
