Oliver Twinsafe, a UK manufacturer
of specialist pipeline valves, has
upgraded its production facilities
with the installation of a selfcontained
Enviraclean blast room
with abrasive recovery system and
high-performance sound insulation
from Hodge Clemco.

The blast room is located beneath
a canopy outside the factory beside
the production area, so is convenient
to use while avoiding any potential
problems of noise or dust within the
building. It is 4m long x 3m wide x
2.5m high and has double access
doors at one end to accommodate
larger components.Modular doubleskinned
panels with an acoustic
lining have been used for the
construction, which reduces the
noise that can be heard outside.
Doors are interlocked to prevent
entry while blasting is in progress,
and walls are lined with rubber
curtains to reduce abrasion. Air inlet
ducts and exhaust air outlets have
been positioned to ensure effective
cross-draught ventilation in order to
provide good visibility for operators.
