| RLP 100: Pneumatic air-volume controller
How energy efficiency is improved
Enables the demand-led volume flow control of fume cupboards, laboratory rooms and clean rooms.
Areas of application
Specially designed for volume flow control equipment in VAV installations. In combination with a highly accurate, static differential pressure transmitter and a pneumatic damper drive, it is possible to control laboratory fume cupboards, laboratory rooms and room pressures.
Properties
- ATEX certification for use in Zone 1 potentially explosive areas
- Conformity tested as per EN 13463-1 and EN 1127-1 (Ex II 2 G T6)
- Control of constant, switchable or variable air volumes
- Highly accurate, static differential pressure sensor with large measuring range (1 to 160 Pa)
- Controller front panel is printed with circuit diagram for rapid identification of function
- Glass-fibre-reinforced thermoplastic housing suitable for wall or top-hat rail mounting (rail EN 60715)
- Compressed-air connections with Rp 1/8" female thread
- Special measuring connection for recording the volume flow with M4 connector
- Low-pressure connections in form of stepped nipples for flexible plastic hose (internal Ø 4 and 6 mm)
- Complies with directive 97/23/EC Art. 3.3 on pressure equipment
Technical description
- Supply pressure 1.3 bar ± 0.1
