ERVS Single duct vav box in galvanised steel.
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).
Models
- ERVS single casing.
- ERVS-I double casing.
On demand
- VAV-Compact, AC/DC 24 V, Bacnet MS/TP, Modbus RTU, MP-Bus, IP54 LMV-D3-MOD (5Nm);
- VAV-Compact, AC/DC 24 V, KNX (S-Mode), IP54 LMV-D3-KNX (5Nm).
Accessories
Water or electric reheat coil (prices on request).
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.
