| ASV115CF152: VAV compact controller
How energy efficiency is improved
Provides demand-led control of the air volume to optimise energy consumption in ventilation systems. Differential pressures up to 1 Pacan be controlled, providing very small volume flows with extremely low duct pressures and energy consumption.
Areas of application
Controlling the exhaust air from fume cupboards, and controlling supply and exhaust air in laboratories, clean rooms, wards or operatingtheatres in conjunction with a volume flow box.
Features
- Static differential pressure recording based on the capacitive method of measurement
- Can be used in areas with dirty or contaminated exhaust air.
- High-precision measurement of differential pressures with ranges of up to 300 Pa
- Calibrated version available for pharmaceutical applications
- Variable running times from 3 to 15 s for fast control loops
- Brushless DC motor provides the lowest possible energy consumption and a long service life
- Electronic/mechanical torque cut-off for safe operation
- Extremely simple installation due to self-centring shaft 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 and SLC (SAUTER Local Communication) protocol
- Extremely easy to parameterise using the SAUTER CASE VAV software
