ASV115CF132: Compact volumeflow controller standard

How energy efficiency is improved
Provides demand-led control of the air volume to optimise energy consumption in ventilation systems. Differential pressures of up to 1 Pa can be controlled, providing very small volume flows with extremely low duct pressures and energy consumption.

Areas of application
Controlling supply and exhaust air in, for example, offices, conference rooms or hotel rooms in conjunction with a volume flow box or a damper and a flow probe.

Features

• Static measurement of differential pressure based on the capacitive method
• Can be used in areas with dirty or contaminated exhaust air
• High-precision measurement of differential pressures with ranges of up to 300 Pa
• Variable running times from 30 to 120 seconds
• Brushless DC motor provides the lowest possible energy consumption and a long service life
• Electronic torque cut-off for safe operation
• Easy to fit due to self-centring spindle adaptor
• Transmission can be disengaged for manual adjustment and positioning of the damper
• Power cable 0.5 m long, 10×0.32 mm², fixed to housing
• Can easily be combined with RLE150F100 or NRT300
• Fail-safe control for critical applications
• RS-485 bus interface for up to 31 subscribers in a segment with SLC (SAUTER Local Communication) protocol
• Easy to parameterise using the SAUTER CASE VAV software
• Constant air volume control using parameterisable inputs
