Description

Product Description

Castle Variable Air Volume (VAV) Terminal Units regulate conditioned airflow to individual zones based on thermostat demande — varying air volume at constant temperature pour optimal energy efficiency. Galvanized steel casing avec acoustic lining, multipoint airflow sensor, modulating actuator et DDC controller. Compatible avec BACnet et Modbus BMS protocols. Available in single-duct et dual-duct configurations.

Pressure Independent

Multipoint flow grid maintains set airflow regardless of upstream duct pressure changes.

BMS Integration

Built-in DDC controller avec BACnet/Modbus — seamless integration avec any Building Management System.

Energy Efficient

Reduces fan energy by varying airflow to match actual zone demande — 30-50% energy savings vs CAV systems.

Low Nonise

Acoustic-lined casing et aerodynamic internals — NC 25-35 pour occupied zone comfout.

ISO 9001:2015 Certified

Quality management system certified by IGC, covering all stages de raw material to final delivery.

SMACNA & DW144 Compliant

Manufactured to le latest edition of SMACNA HVAC Duct Construction Standards et DW144.

Custom Sizes Available
