Introduction
Underground Modules are designed
to reduce environmental impact that
is not provided by traditional cabinet
installations or masonry structures.
This solution reduces noise pollution
and environmental impact, provides
protection against acts of vandalism or
accidents.
The module consists of two main parts:
• Metal underground container
• Gas control unit
The metal container is a non-pressurized
type with connections suitable for direct
welding to inlet and outlet piping.
The gas control unit is contained inside
the metal container, consisting of a
regulating line complete with by-pass
(MIR/ series excluded) assembled with
standard equipment.
The gas control unit is easily accessible
for maintenance or replacement.
