Following the successful RIGHT CHEMISTRY
installation and trial of a TLV
Euro Engineering steam
pressure reducing system at its
Sturminster Newton site two
years ago, linen hire and
laundry specialist Johnsons
Stalbridge Linen Services has
installed seven additional
systems at three more sites.

Each of the four laundries
uses steam for roller ironers,
through which linen is passed
for drying and ironing. Steam
is generated at approximately
10 bar, which is ideal to heat
the ironers to the temperature
required for cotton-based
linen products.However, in
recent years more syntheticbased
linen products
necessitated a reduction in
steam pressure to approximately
6 to 8 bar to give
them the lower temperature
required for these materials.

TLV engineers recommended
the combined valve,
trap and separator
arrangement of its CV-COS
coupled with a pressure
sensor and controller on the
steam branch line
immediately before the roller
ironer. The CV-COS
automatically controls
pressure, temperature or the
flow rate of steam; and
removes condensate at a
separation efficiency rate up
to 98%. The electropneumatic
pressure reducing
valve adds a convenient
control function to a range
that already combines a
pressure reducing valve,
separator and steam trap in
one compact unit.

The specification is said to
save space, simplify system
layout, piping and maintenance,
and eliminate the risk of
damage and incorrect
adjustment.
