Available in two versions:
GRT70 = 70 WATT (for CSN 1 ÷ 5)
GRT120 = 120 WATT (for CSN 6 ÷ 12)
DESCRIPTION
The CSN waterproof enclosure is
designed for the piloting of diaphragm
valves type VEM, and is available in the
following models:
• CSN 5: from 1 to 5 solenoid pilots
• CSN 8: from 6 to 8 solenoid pilots
• CSN 12: from 9 to 12 solenoid pilots
The CSN enclosure is IP67 approved.
Each solenoid pilot, energised in
sequence, commands a corresponding
VEM type diaphragm valve, by way
of O.D. 8 mm pneumatic tube being
less than 2 metres in length. The CSN
enclosures are supplied complete with
fixing brackets. The common terminal
is pre-wired. The CSN solenoid base
is manufactured from extruded
aluminium, while the cover is in
diecast aluminium, both anodised’ for
protection against aggressive agents.
The CSN enclosure features a common
exhaust port, located on the underside
of the unit. The exhaust is open to the
atmosphere and can be piped or muted
with a silencer. For low-temperature
applications, enclosures are available
with a thermostatically controlled
heating device model “GRT” that keeps
the internal temperature at + 4°C.
The GRT is available in two models:
• GRT 70: for CSN 5
• GRT 120: for CSN 8 and CSN 12.
The CSN Enclosure conforms to ATEX II
3D Extc IIIC T100° C DC IP67.
