ERVC Circular variable air flow regulators with servomotor LMV-D3MP
Description
These regulators are used to control and maintain the amount of air in VAV systems.
Characteristics
-Galvanised steel sheet casing; -Dynamic Δp probe to measure and maintain the air flow rate according to the room demand; -Galvanised steel damper with sealing gaskets; -Operating range between 20 and 1500 Pa; -Flow rate adjustment and control by means of a linearised motor controller; -Self-generated and radiated noise tests according to the EN ISO 3741 Standard; -Damper tightness test performed according to the EN 1751 Standard. -VAV-COMPACT, AC/DC 24 V, MP-Bus, IP54 LMV-D3-M (5nm) (Standard)
Notes
For correct pressure readings and for a flow rate tolerance of 5%, a straight duct with a length equal to 2/3 times the regulator diameter must be provided upstream. Otherwise, the air flow rate may vary between 10% and 20% from the calibrated value.
Models
- ERVC single casing.
- ERVC-I double casing.
